 About Lumafield:&nbsp;
 
 
 
 
 
 
 Lumafield was founded in 2019 to upgrade manufacturing.
 
 
 
 
 
 We are engineers with deep experience across the product development cycle, from initial ideas to shipping hardware, across industries and specializations, who became frustrated by the cost and complexity of modern manufacturing. So we decided to upgrade it.
 
 
 
 
 
 Engineers make million-dollar decisions every day, and they need tools that give them the greatest possible insight into their products. By offering unprecedented visibility into products, as well as AI-driven tools that highlight problems and generate quantitative data, Lumafield promises to revolutionize the way complex products are created, manufactured, and used across industries. We started with industrial CT scanning, which for us was the most valuable but underutilized tool in the manufacturing toolbox, enabling us to rapidly inspect essential components non-destructively.
 
 
 
 
 
 We rebuilt the whole system, from X-ray capture, to computer vision analysis, to web-based collaboration, to the entire business model, making the most advanced manufacturing tech more accessible to every industry. Our company, like our platform, is designed for upgrades. We&rsquo;re building for greater intelligence, autonomy, and speed. For deeper vision, operational excellence, and powerful insights. And then we'll upgrade it all again.
 
 
 
 
 
 Lumafield is headquartered in Cambridge, MA, and has an office in San Francisco, CA.

 Who We Are
 
 
 Notion is the collaborative AI workspace where teams and agents think together. We're building one place where your knowledge, projects, meetings, and AI tools live side by side, so work is faster, clearer, and less fragmented. Millions of individuals, small teams, and large companies run their work on Notion.
 
 
 Notinos (our employees) are customer zero in bringing this future of work to life. We care about craft, building things that last, and the belief that great work is still fundamentally human. Our goal isn&rsquo;t to ship the next feature. Each and every team of Notinos is working to set the standard for how humans work together in the AI era. From building a business&rsquo;s system of record to making and managing AI agents to automating away the busy work, we care deeply about giving our customers more time for their life&rsquo;s work.
 
 
 
 About The Role
 
 
 
 As an engineer at Notion, you&rsquo;ll help shape core user experiences and accelerate how people discover value in Notion. You'll tackle meaningful challenges with increasing autonomy, crafting code that millions of users will experience. You'll take ownership of projects that matter, make critical technical decisions, and contribute your unique perspective to our product vision. Working alongside passionate experts across design, product, and data, you'll help shape the future of how people work.
 
 
 We&rsquo;re hiring new grad engineers to join us across several teams at Notion. Your recruiter will partner with you to find the team that best aligns with your interests and where you can make the highest impact.
 
 
 What You'll Achieve
 
 
 <ul>
 <li>
 You'll work with others to plan, shape, and build new product features from start to finish: through conception, research, implementation, and maintenance. For example, you might work on driving adoption, by instrumenting key onboarding moments and iterating on activation flows.
 </li>
 <li>
 You'll help improve performance and reliability, or polish existing features. For example, you might update our spell checker to sync dictionaries across browsers or improve search to index file attachments.
 </li>
 <li>
 You'll build internal tools to support simplicity and productivity for the whole team. This might include writing a script to import user feedback into Notion.
 
 
 </li>
 </ul>
 
 Qualifications
 
 
 
 <ul>
 <li>
 Pursuing a bachelor's or master&rsquo;s degree in computer science, engineering, or another related field. Must be able to start full-time prior to July 27, 2026.

 Working towards a proficiency of one or more programming languages such as TypeScript, Node.js, or Python.
 
 
 </li>
 </ul>
 Skills You'll Need to Bring
 
 
 <ul>
 <li>
 Impact-driven approach to technology: You see technologies as tools to achieve user impact rather than ends in themselves. You care more about building successful systems that solve real problems than about using specific tech stacks or following trends.
 </li>
 <ul>
 <li>
 You stay current with the latest tools like Codex, Claude Code, and other AI-assisted development environments. You're pragmatic about choosing the right tool for the job, focusing on what delivers the most value to users.
 </li>
 </ul>
 <li>
 Thoughtful problem-solving: For you, problem-solving starts with a clear and accurate understanding of the context. You can decompose tricky problems and work towards a clean solution, by yourself or with teammates. You're comfortable asking for help when you get stuck. You think about the implications of what you're building and how it will impact real people's lives.
 </li>
 <li>
 Own the outcome: You own your work, communicating clearly about progress and blockers. You don't wait for instructions for every step but rather show initiative in identifying what needs to be done and driving projects forward. You ask questions when needed while independently finding solutions to problems.
 </li>
 <li>
 Team player: For you, work isn't a solo endeavor. You enjoy collaborating cross-functionally to accomplish shared goals, and you care about learning, growing, and helping others to do the same.
 </li>
 <li>
 Passion for web applications: You can work with others to build and maintain quality user interfaces for a big audience, using Web technologies like HTML, CSS, JavaScript, and a modern UI framework like React.
 </li>
 <li>
 Familiarity with backend systems: You understand how parts of a system fit together&mdash;from the user interface to the data model. Familiarity with database systems like Postgres, MySQL or MongoDB is a plus.
 
 </li>
 </ul>
 Nice to Haves
 
 
 <ul>
 <li>
 You have experience with any part of our technology stack: React, TypeScript, Node.js, Postgres, and Elasticsearch.
 </li>
 <li>
 You&rsquo;re a builder who finds joy in building software solutions for yourself or others.
 </li>
 <li>
 You care about the interaction between technology and society, the ways in which they inform each other, and our responsibility as technologists to be conscious of that relationship.
 </li>
 <li>
 You've heard of computing pioneers like Ada Lovelace, Douglas Engelbart, Alan Kay, and others&mdash;and understand why we're big fans of their work.
 
 
 </li>
 </ul>
 Notion is committed to providing highly competitive cash compensation, equity, and benefits. The compensation offered for this role will be based on multiple factors such as location, the role&rsquo;s scope and complexity, and the candidate&rsquo;s experience and expertise, and may vary from the range provided below.

 By clicking &ldquo;Submit Application&rdquo;, I understand and agree that Notion and its affiliates and subsidiaries will collect and process my information in accordance with Notion&rsquo;s Global Recruiting Privacy Policy.
 
 
 A Note on AI
 
 
 You don&rsquo;t need deep AI expertise for every role, but we do expect every Notino to be intellectually curious, drawn to tinkering and discovery, and excited to use AI as a real collaborator in their work. For some roles, AI fluency is a core requirement &mdash; when that&rsquo;s the case, we'll say so explicitly in the qualifications. People who thrive here don&rsquo;t treat AI as a novelty. They use it to think better, and make their work easier for others to build on.

 Putting care and intention into every task, striving for excellence, and taking deep ownership of the quality and outcome of your work. Craftsmanship means never settling for &ldquo;just fine.&rdquo; We sweat the details because details compound. Whether it&rsquo;s a product feature, an internal doc, or a sales call &mdash; we treat it as a reflection of our standards. We aim to deliver jaw-dropping customer experiences by being curious, meticulous, and proud of what we build &mdash; even when nobody&rsquo;s watching.
 
 
 
 
 We are &ldquo;majos&rdquo;
 
 
 
 
 Be friendly &amp; have fun with your coworkers. Always be genuine &amp; honest, but kind. &ldquo;Majo&rdquo; is our way of saying: be a good human. Be approachable, helpful, and warm. We&rsquo;re building something ambitious, and it&rsquo;s easier (and more fun) when we enjoy the ride together. We give feedback with kindness, challenge each other with respect, and celebrate wins together without ego.
 
 
 
 
 Urgency with Focus
 
 
 
 
 Create the highest impact in the shortest amount of time. Move fast, but in the right direction. We operate with speed because time is our most limited resource. But speed without focus is chaos. We prioritize ruthlessly, act decisively, and stay aligned. We aim for high leverage: the biggest results from the simplest, smartest actions. We&rsquo;re running a high-speed marathon &mdash; not a sprint with no strategy.
 
 
 
 
 Talent Density and Meritocracy
 
 
 
 
 Hire only people who can raise the average; &lsquo;exceptional performance is the passing grade.&rsquo; Ability trumps seniority. We believe the best teams are built on talent density &mdash; every hire should raise the bar. We reward contribution, not titles or tenure. We give ownership to those who earn it, and we all hold each other to a high standard. A-players want to work with other A-players &mdash; that&rsquo;s how we win.
 
 
 
 
 First-Principles Thinking
 
 
 
 
 Strip a problem to physics-level facts, ignore industry dogma, rebuild the solution from scratch. We don&rsquo;t copy-paste solutions. We go back to basics, ask why things are the way they are, and rebuild from the ground up if needed. This mindset pushes us to innovate, challenge stale assumptions, and move faster than incumbents. It&rsquo;s how we build what others think is impossible

Software Engineer - Full-Stack

Alembic Pharmaceuticals Ltd

<div><h2 class="jobSectionHeader">The Context</h2>
Hi, I'm Logan, and I lead Talent at Alembic. I came to Alembic because the founders believe what I believe: investing in people is how you build the company, not a cost of building it. Done right, that buys three things, in order &mdash; a team that demands excellence, work that carries daily personal meaning, and a real shot at generational wealth for the people who build it. I haven't often found all three in one place.
Here's my situation, plainly: we have 20+ funded open roles, 16 of them technical &mdash; research engineers implementing causal mathematics in CUDA and C++, SREs running one of the fastest private supercomputers in the world, backend and data engineers scaling a platform that Fortune 100 companies use to make multimillion-dollar decisions. The company just raised a $145M Series B and expects to roughly double in the next year. Right now, the team responsible for all of that hiring is small. You would be the unlock.
I'll tell you how we work, because it's the best predictor of whether you'll want this job. We run structured hiring &mdash; scorecards before searches, calibrated loops, feedback in 48 hours &mdash; because hiring is too important for gut feel. We treat speed as our advantage against bigger brands: attention, time, and effort are things we can out-invest. Our operating loop is Learn Build Share Repeat, and we publish our work &mdash; including the materials we used to write this very listing. And we are AI-native, in the practical sense: we experiment with new tools constantly and expect each other to keep hunting for a better way. If you read that list and felt something click, keep reading.
One more thing worth saying: we wrote our hiring playbook down before we wrote this job ad, and we're sharing it openly here.<h2 class="jobSectionHeader">
About Us</h2>
Alembic is the pioneering Causal AI platform. We help the world's largest enterprises move past correlation to prove what actually drives business outcomes &mdash; the question marketing and growth teams have never been able to answer with confidence. Fortune 100 companies including Nvidia, Delta Air Lines, and Mars use Alembic to make multimillion-dollar decisions on trusted, causal evidence.
We're backed by a $145M Series B from WndrCo (founded by Jeffrey Katzenberg), Jensen Huang, Joe Montana, Prysm Capital, and Accenture. Our models run on our own NVIDIA DGX SuperPOD built on Grace Blackwell infrastructure &mdash; one of the fastest private supercomputers in the world. (We've melted GPUs getting here.)<h2 class="jobSectionHeader">
The Role</h2>
Your mission: own and close our priority technical searches, so that a team of top-decile engineers can keep shipping causal AI for Fortune 100 customers.
You'll carry 6&ndash;8 technical searches full-cycle &mdash; backend, infrastructure/SRE, and data engineering &mdash; partnering directly with engineering leadership. This is a carry-the-searches-yourself role with real authority over how they're run, not a coordination job and not a management job.
Success in the first six months looks like:<ul><li>
You know the business cold. You can pitch Alembic &mdash; causal AI versus correlation, our customers, our infrastructure &mdash; credibly to a senior engineer, in your own words.</li><li>
You own calibrated scorecards and live pipelines on every search you carry, and hiring managers trust your judgment enough that your push-back changes how searches are run.</li><li>
You've closed multiple technical hires at our bar &mdash; including candidates who had other offers.</li><li>
Searches you run move fast: structured loops, same-week feedback, weeks not months from first screen to offer.</li></ul><h2 class="jobSectionHeader">
What Will Help You Succeed</h2><ul><li>
5+ years of full-cycle technical recruiting &mdash; software, infrastructure, or ML &mdash; at companies with a genuinely high bar.</li><li>
A closer's track record. You can tell us, specifically, about candidates you won against stronger brands, and how.</li><li>
You learn businesses fast and sell them fluently. Recruiting is marketing and sales, and you treat it that way.</li><li>
A consultative spine: you push back on hiring teams rather than push weak candidates, and you have the evidence-based arguments to do it well.</li><li>
High content-to-word ratio. You speak and write plainly, honestly, and proactively. Zero fluff.</li><li>
Urgency and meticulous detail at the same time &mdash; you don't trade one for the other.</li><li>
Data proficiency: you diagnose your funnels by root cause, not anecdote.</li><li>
An AI-native practice: you regularly experiment with new tools and methods, and you're constantly looking for alpha.</li></ul><h2 class="jobSectionHeader">
This role is probably not for you if:</h2><ul><li>
You need a coordinator, a sourcer, and an ops layer behind you before you can move.</li><li>
You measure your work in activity &mdash; submittals, screens, calls &mdash; rather than hires and quality.</li><li>
You're ready to manage a team rather than carry searches personally. (That path can open here; it isn't where this starts.)</li><li>
Five days a week in our San Francisco office isn't workable for you. We're in the room with the engineers we hire for, and it matters.</li><li>
You see AI tooling as a threat or a gimmick rather than daily practice.</li></ul><h2 class="jobSectionHeader">
Why You Might Be Excited About Alembic</h2><ul><li>
Your work is the company's bottleneck-breaker: 19 funded searches stand between Alembic and its next chapter. Few recruiting seats anywhere have this much concentrated leverage.</li><li>
A hiring system worth joining: Structured hiring, scorecards, batch review, real candidate-experience standards &mdash; you're inheriting a thoughtful machine and making it better, not cleaning up a mess.</li><li>
A story engineers actually want to hear: Causal AI for the Fortune 100, mathematics implemented on a private supercomputer. You'll never have to sell vapor.</li><li>
AI-native by design: We'll fund your experiments. The recruiter-as-creator era is here, and this team intends to be evidence of it.</li><li>
Series B momentum, real ownership: Meaningful equity at a Series B company that's raised $145M, with proven product-market fit and Fortune 100 traction &mdash; and a talent function you'll help build as the org doubles.</li></ul><h2 class="jobSectionHeader">
Why You Might Not Be Excited</h2><ul><li>
We're building the talent function while running it. You'll define process, not inherit it.</li><li>
Brevity is strength here &mdash; feedback is direct, meetings are short, and writing matters. If you prefer a softer communication culture, this will feel sharp.</li><li>
Priorities shift as we grow. We have real paying customers and a playbook, and we still move at startup speed at Series B scale.</li></ul><h2 class="jobSectionHeader">
How to Apply</h2>
Take your time with your application. We will review every application after the deadline (Wed July 15, 9:00 PM PT) and speak with a shortlist based on what you submit. There are no prizes for applying first, and no advantage gained by messaging the team &mdash; please put your energy into the application itself.
Compensation Range: $125K - $160K</div>
