Eleos Technologies

<div><div>About us</div>
<div></div>
<div>Eleos Technologies is a growing 12-year-old company building communication software for truck drivers and field workers.</div>
<div></div>
<div>We&rsquo;re helping a diverse mix of customers, from mom and pop operations to thousand-truck fleets, improve how they communicate with their employees by tackling information overload, reducing phone calls, and eliminating obsolete technologies. As we help fleets develop better tools, we aspire to be known for our innovation, reliability, and ability to make a difference for them and their drivers.</div>
<div></div>
<div>Our engineering team has been 100% distributed since day one. This means we&rsquo;re tooled up to handle product, architectural, technical, and ops work all from home or remote. You won&rsquo;t miss out on office conversations, and you won&rsquo;t have to learn to drive a telepresence robot.</div>
<div></div>
<div>We began life as a bootstrapped startup, which allowed us to focus on building products our customers love. Today, we're part of the Knight-Swift family, which has allowed us to keep our focus and the freedom to build the best products we can for the transportation industry. We offer robust healthcare (dental, medical, vision), paid time off, and a generous equipment budget.</div><div></div><div><br>
<h2 class="jobSectionHeader"><b>
About the role</b></h2>
<p>
Our app is more than the usual &quot;CRUD and chat&quot;: in addition to industry-leading truck navigation and planning tools, we&rsquo;ve got advanced algorithms for identifying the best and safest vehicle route, document scanning, and more&mdash;all on the device.</p>
<p>
As a senior member of our iOS team, you&rsquo;ll get to leave your mark across the app&rsquo;s architecture, UI, and all the way down to the database and network guts. You&rsquo;ll work directly with peers who maintain our Android app and the server systems that provide our customers with a stable API and handle user data synchronization.</p>
<p>
Tens of thousands of people across the country rely on our app to do their jobs, and we take quality seriously. We have an automated acceptance test suite we run in a cloud-hosted provider, plus a great dedicated QA team responsible for manual testing and helping reproduce issues reported from the field. You&rsquo;ll write automated tests for the code you write and work to both share and expand your skills around automated testing. We have CI that produces builds for the whole team to try within a few minutes of a commit or pull request being opened and a similar process for cutting release-ready builds for distribution, so you can generally stay focused on the work you love and not Xcode toil.</p>
</div>
<h3 class="jobSectionHeader"><b>About you</b></h3><div>
<p>
We're looking for a senior engineer who can help maintain, evolve, and improve our iOS app, which is the single pane through which about half of our users experience our core product. (The other half use Android!)</p>
<p>
We&rsquo;re looking for a product-minded engineer who wants to understand the problem behind the requirement, not just implement the requested solution. You&rsquo;ll partner closely with members of the team to refine ideas, identify edge cases, and suggest approaches that may not have been apparent when the work was originally defined.</p>
<p>
You should be comfortable asking thoughtful questions, respectfully challenging assumptions, and presenting technical tradeoffs in a way that helps the team make better decisions. We value engineers who take ownership of the outcome, not just the completion of the ticket, and who remain involved through testing and real world feedback.</p>
<p>
You should be extremely comfortable working with Xcode, implementing and evolving user interfaces with both UIKit and SwiftUI, managing network requests and model state, and persisting to disk using Core Data or SQLite. You should have experience working with both Swift and Objective-C, as we have a mixture of both. (We write almost all new code in Swift, but as a small team, we&rsquo;re in no hurry to rewrite battle-tested Objective-C portions of the app until there&rsquo;s a compelling reason to do so.)</p>
<p>
We'll work together and pair often to get you ramped up, and the nature of our product means you'll continue to work closely with the whole team to move it forward even as you settle in. We'd like someone who's both ready to teach others (you'll know things we don't!) and learn from co-workers in a fun, productive, and respectful environment.</p>
<p>
You must live in the United States to be eligible for this role.</p>
</div><h3 class="jobSectionHeader"><b>
Key skills</b></h3><div>
<ul><li>4+ years professional experience building or maintaining a shipping native iOS app in some mixture of Swift and Objective-C, including ownership of substantial features or technical systems</li>
<li>Ability to turn product requirements into technical and UX options</li>
<li>A collaborative mindset and willingness to respectfully challenge requirements and surface overlooked edge cases and recommend simpler or more valuable solutions</li>
<li>Strong ownership instincts that follows the work from planning, implementation, to ongoing support once released</li>
<li>Experience writing UI automation tests</li>
<li>Ability to diagnose nondeterministic failures involving async behavior, networking, and differences between simulators and real devices</li>
<li>Effectively use Xcode&rsquo;s Instruments suite to diagnose and fix bottlenecks, UI hitches, and memory leaks</li>
<li>Experience diagnosing issues using crash reporting, logging, analytics, and CI or automated test output</li>
<li>Able to balance human- and LLM-driven software development workflows and bring experience, judgement, and curiosity to the process while retaining ownership of the output and results</li>
<li>The ability to quickly convey ideas, opinions, and technical details in written English</li>
<li>Able to work 9-5 Eastern, Central, or Mountain Time, to facilitate real time collaboration when needed</li>
</ul></div><h3 class="jobSectionHeader"><b>Not requirements, but things to mention if they apply to you</b></h3><div>

Senior Full Stack JavaScript Engineer

Mill

<div><div><p>Mill is a waste prevention technology company reimagining what it means to eliminate waste, starting with food. We build smart systems and infrastructure for homes, businesses, and municipalities that transform food scraps from landfill-bound waste into valuable resources, including chicken feed. Tens of thousands of Mill's residential food recyclers are already helping households divert millions of pounds of food scraps every year, paving the way for our upcoming launch of Mill Commercial&mdash;the industry's first end-to-end solution for managing, understanding, and preventing food waste in commercial environments (e.g. grocery, restaurants, food services). At Mill, we are passionate about building easy-to-use, beautifully designed technologies that keep food in the food system and out of landfills.</p></div><p>
We are seeking a highly skilled Senior Full Stack Engineer to join our engineering team. This is an individual contributor technical leadership role reporting to the Director of Software Engineering. You will drive the technical direction of your project area and write high-quality code across the stack, while mentoring engineers around you.</p>
<p>
We've moved away from a frontend/backend split at Mill: every engineer here works full stack, typically leaning toward one side based on strength and interest, and teams are organized around projects rather than layers of the stack. You'll likely anchor on a given project for a sustained stretch &mdash; enough to build real depth and avoid constant context-switching &mdash; with real opportunities to rotate onto new projects and parts of the codebase over time.</p>
<p>
AI-assisted development is core to how we build software, not a peripheral tool. We expect fluency with tools like Claude Code as part of your daily workflow, and as a senior level engineer, a role in raising the bar for how the team uses them.</p>
<h2 class="jobSectionHeader"><b>
Key Responsibilities</b></h2>
<p><b>
Technical Leadership</b></p>
<div>
<ul><li>Lead the technical design and execution of full-stack web applications, ensuring alignment with business objectives and technical standards</li></ul>
<ul><li>Design and implement scalable, secure, and efficient full-stack solutions</li></ul>
<ul><li>Own estimates and technical delivery plans and surface risks early</li></ul>
</div>
<p><b>Development and Implementation</b></p>
<div>
<ul><li>Craft elegant, documented, and sustainable code spanning our full web stack, remaining ready to provide support for our native mobile environment when required</li></ul>
<ul><li>Develop and optimize API and user interfaces</li></ul>
<ul><li>Use AI-assisted development tools fluently as a standard part of how you write, review, and ship code</li></ul>
</div>
<p><b>Team Collaboration</b></p>
<div>
<ul><li>Mentor junior engineers, fostering a culture of continuous learning and improvement.</li></ul>
<ul><li>Conduct code reviews and provide constructive feedback to maintain high coding standards.</li></ul>

</div><h2 class="jobSectionHeader"><b>Required Qualifications</b></h2>
<ul><li>5+ years of professional experience in software development with a focus on full-stack development</li>
<li>Deep experience with modern frontend frameworks (e.g. React, Vue, Angular, or SvelteKit) &mdash; we use SvelteKit at Mill but recognize that strong React/Vue/Angular experience is highly transferable, especially with AI-assisted tooling, so prior SvelteKit experience is preferred but not required</li>
<li>Strong backend experience with TypeScript/Node.js; comfort with serverless architectures (e.g. AWS Lambda)</li>
<li>Solid understanding of SQL and NoSQL database systems</li>
<li>Experience with cloud platforms (we run AWS) and modern deployment workflows</li>
<li>Fluency with AI-assisted development workflows (e.g. Claude Code, Copilot) as a genuine part of your day-to-day practice &mdash; not occasional or exploratory use</li>
<li>Strong software architecture fundamentals (e.g. microservices, serverless)</li>
<li>Excellent problem-solving and debugging skills</li>
</ul><h2 class="jobSectionHeader"><b>Preferred Qualifications</b></h2>
<ul><li>Experience with our specific stack: SvelteKit (web, deployed on Vercel), React Native (mobile), AWS Lambda with CDK (TypeScript) and Middy</li>
<li>Familiarity with DevOps practices and infrastructure as code (e.g. Terraform, CDK)</li>
<li>Strong understanding of security best practices in web development</li>
<li>Prior experience working at a hardware company, particularly collaborating with firmware teams &mdash; we build physical devices, not just software, and comfort working alongside hardware/firmware engineers is a plus</li>
</ul><h2 class="jobSectionHeader"><b>Key Attributes</b></h2>
<ul><li>Strong communication and interpersonal skills &mdash; especially the ability to partner closely with product without owning the roadmap</li>
<li>Comfortable holding technical ownership of a project over a sustained period, while staying energized by the opportunity to rotate onto new problems periodically</li>
<li>Proactive, self-driven, and eager to take ownership of projects</li>
<li>Passion for mentoring and developing engineering talent</li>

Senior Full Stack Engineer

Mindrift

<div>
 <em>
  Please submit your CV in English and indicate your level of English proficiency.
  <br/>
  <br/>
 </em>
 Mindrift connects specialists with project-based AI opportunities for leading tech companies, focused on testing, evaluating, and improving AI systems. Participation is project-based, not permanent employment.What this opportunity involves:
 <br/>
 <br/>
 We're building a dataset to evaluate AI coding agents - how well a model handles real-world developer tasks.
 <br/>
 <br/>
 You'll create challenging tasks and evaluation criteria within realistic simulated environments:
 <br/>
 <br/>
 <ul>
  <li>
   Build realistic developer environments - a virtual company with codebase, infrastructure, and context (tickets, docs, conversations) that forms a believable development history
  </li>
  <li>
   Design tasks from intermediate states of these environments - craft the prompt, define what "solved" means, and ensure the task is solvable by an AI agent
  </li>
  <li>
   Write tests that verify agent solutions - accept all valid approaches and reject incorrect ones, neither too strict nor too lenient
  </li>
  <li>
   Iterate on tasks and tests based on QA feedback - review agent solutions, analyze failures, and refine until the evaluation is fair and robust
   <br/>
   <br/>
  </li>
 </ul>
 <strong>
  What this is NOT:
  <br/>
  <br/>
 </strong>
 <ul>
  <li>
   Not data labeling
  </li>
  <li>
   Not prompt engineering
  </li>
  <li>
   Not writing code from scratch - the agent writes most of the code; you guide and evaluate
   <br/>
   <br/>
  </li>
 </ul>
 <strong>
  What we look for:
  <br/>
  <br/>
 </strong>
 <ul>
  <li>
   8+ years in software development
  </li>
  <li>
   Core stack: Python (FastAPI), JavaScript/TypeScript (React), Docker, Postgres, Kafka, Redis
  </li>
  <li>
   Experience writing tests (functional, integration)
  </li>
  <li>
   English proficiency - B2+
   <br/>
   <br/>
  </li>
 </ul>
 <strong>
  Why this is hard:
  <br/>
  <br/>
 </strong>
 Frontier models are already good at coding. Creating a task that genuinely challenges the best models is non-trivial. You need to deeply understand where models fail and what scenarios reveal the difference between a good and a bad solution. Tasks have many valid solutions - writing tests that accept all correct solutions and reject incorrect ones is harder than it sounds.
