Role<h1 class="jobSectionHeader">
Who this role is for</h1>
This role is for an experienced product engineer who wants real ownership, real leverage, and real impact.
You have already shipped meaningful products and systems. You are comfortable taking responsibility for outcomes, not just execution. You care deeply about product quality, system design, and user experience, and you want your decisions to shape the direction of what gets built.
You thrive in environments with ambiguity. You are energized by loosely defined problems and take initiative to clarify goals, explore constraints, and drive toward strong solutions. You are trusted to make technical and product tradeoffs independently and to mentor others by example.
You enjoy working across the stack and across disciplines. You move fluidly between backend systems, frontend interfaces, and product decisions. You want to help define how a product is built, not just implement tickets.
This is not a role for someone who wants narrow scope or heavy process. It is for someone who wants to operate as a force multiplier.<h2 class="jobSectionHeader">
What you will do</h2>
You will own complex, high impact product work end to end, from early problem framing through production and iteration.
You will:<ul><li>
Lead the design and implementation of user facing features across frontend and backend using TypeScript, React, Tailwind, and Postgres</li><li>
Translate ambiguous product goals into clear technical plans and shipped outcomes</li><li>
Partner closely with product and design to shape roadmap decisions and execution strategy</li><li>
Talk directly with users to understand workflows, pain points, and opportunities</li><li> 
Drive fast iteration loops using feedback, data, and firsthand product usage</li><li>
Raise the quality bar through thoughtful system design, testing, and code review</li><li>
Identify and resolve structural issues that slow the team or degrade product quality</li><li>
Mentor junior engineers through pairing, feedback, and setting strong technical examples</li><li>
Contribute to a culture of ownership, clarity, and high standards</li></ul> 
You will be expected to move fast while thinking holistically, choosing solutions that scale with the product and team rather than optimizing for short term convenience.
How you will be successful
Your success will be measured by:<ul><li>
End to end ownership 
You take responsibility for important product areas, drive decisions, and reliably deliver high quality features without heavy oversight.</li><li> 
Technical and product leadership 
You make sound architectural and product tradeoffs, improve system quality over time, and elevate the thinking of those around you.</li><li> 
Shipped product impact 
Your work measurably improves user experience, product depth, reliability, and development velocity.</li></ul><h1 class="jobSectionHeader"> 
Required background</h1>
Strong candidates typically have:<ul><li>
Several years of experience building and shipping production software</li><li>
A strong technical foundation from a CS program or equivalent real world experience</li><li>
Experience owning significant product or system areas end to end</li><li>
Deep comfort with TypeScript and modern frontend development</li><li>
Solid backend fundamentals including data modeling, APIs, and system design</li><li>
Strong debugging skills and the ability to reason through complex systems</li><li>
Clear written and verbal communication</li><li>
A demonstrated ability to learn new domains quickly and apply them in practice</li><li>
Experience operating in fast paced environments with high ownership</li></ul><h1 class="jobSectionHeader"> 
Nice to have</h1><ul><li>
Experience at an early stage or high growth startup</li><li>
Experience collaborating deeply with design and product partners</li><li>
A track record of mentoring or leading other engineers</li><li>
Personal projects or writing that demonstrate taste and initiative</li><li>
Interests beyond engineering such as design, writing, economics, or philosophy</li></ul><h1 class="jobSectionHeader"> 
Why this role matters</h1>
We are building ambitious products at the intersection of AI and modern software. Doing that well requires senior product engineers who can think clearly, learn continuously, and ship with conviction.
In this role, you will have outsized influence on the product, the codebase, and the team. You will work on problems that matter, help shape how we build, and play a key role in defining the future of the company.
In all roles 
We look for:
Intense. Ship fast. Cycles are hours, not weeks. Hard to outwork.

 The Role
 
 
 
 We're seeking a full-stack Software Engineer to work on the development of our patient, partner, and company web applications. This role is crucial in creating intuitive, efficient, and responsive user interfaces that will directly impact our users' experience and our platform's success.
 
 
 As a key part of our engineering team, you will build high-performance, scalable, and accessible user interfaces that use AI to serve diverse user groups including rare disease patients, healthcare providers, researchers, and our internal teams.
 
 
 You will join a team that highly leverages the latest AI coding assistants (e.g. Cursor, Claude Code, Codex, etc.) to implement features at very high velocity.
 
 
 Your work will be at the heart of our mission, translating complex health data and research findings into user-friendly interfaces that empower patients, facilitate groundbreaking research, and streamline our internal operations.
 
 
 
 Who You Are
 
 
 
 You&rsquo;re a builder and problem-solver who thrives in fast-paced, innovative environments. You&rsquo;ve worked on consumer or data-rich products, enjoy end-to-end ownership, and collaborate closely with teammates to ship real value. You&rsquo;re comfortable diving into your strengths (frontend, backend, or full-stack) and curious about how AI can improve the experiences we deliver for patients, providers, researchers, and internal teams.
 
 
 You will likely be a fit if you have
 
 
 <ul>
 <li>
 0-3 years of professional software engineering experience with a track record of launching user-facing features or services.
 </li>
 <li>
 Strength in one or more of the following:
 </li>
 <li>
 Frontend: JavaScript/TypeScript with a modern framework (e.g., React/Vue), semantic HTML/CSS, accessibility, and performance for data-heavy UIs.
 </li>
 <li>
 Product Engineering: Strong product sense and UX instincts; you use user needs, data, and experiments to guide decisions and iterate quickly.
 </li>
 <li>
 Working knowledge of performance, scalability, and security fundamentals appropriate to your layer (e.g., web perf, API efficiency, data modeling, auth).
 </li>
 <li>
 Experience with testing (e.g., Jest, React Testing Library, Cypress, PyTest) and comfort with code reviews and iterative development.
 
 
 </li>
 </ul>
 You will receive bonus points if you have
 
 
 <ul>
 <li>
 Experience with frontend state management (e.g., Redux, MobX, Recoil) or a backend framework (e.g., Express, FastAPI, Spring, Fiber).
 </li>
 <li>
 Familiarity with CI/CD pipelines and modern build tooling.
 </li>
 <li>
 Proficiency with databases (SQL or NoSQL) and writing simple queries to inform product decisions.
 </li>
 <li>
 Experience with analytics/experimentation and/or accessibility best practices.
 </li>
 <li>
 Exposure to cloud infrastructure (AWS/GCP/Azure), containers, and observability is a plus.
 
 
 </li>
 </ul>
