Kayzen is accessible through our APIs and user interface.</p>
<p><b>
The Team</b></p>
<p>
The Console team owns the user-facing applications and interfaces that power the Kayzen platform &mdash; from our self-serve campaign management dashboard and real-time reporting suite to internal tooling used by our managed service teams. We work closely with product managers, designers, backend engineers, and data teams to deliver seamless, high-performance experiences. We are responsible for some of the most impactful work at Kayzen, including:</p>
<ul>
<li>&quot;The Console&quot; which is the face of Kayzen we are very proud of.</li>
<li>Complex features which surface a lot of backend infrastructure via console</li>
<li>Almost 100% uptime with very well planned &amp; executed project management</li>
</ul>
<p><i>Sounds interesting. Isn't it?</i></p>
<p><b>
About the Role</b></p>
<p>
We are looking for a coding-first <b>Fullstack Engineer</b> who thrives on turning complex product requirements into high-performance UIs. You should be comfortable working across the stack, contributing to architecture discussions, and be an early adopter of AI-assisted engineering (e.g., Claude Code, Cursor, Copilot) in your daily coding workflow. This role is a strong individual contributor position with room to grow into deeper technical ownership over time.</p>
<p><b>
Responsibilities</b></p>
<ul>
<li>Core responsibilities</li>
<li><ul><li>Design, build, and maintain high-quality features across the Fullstack stack, from UI to API integration</li>
<li>Write clean, well-tested, production-ready code and actively participate in code reviews</li>
<li>Collaborate closely with Product, Design, QA, and Backend teams to deliver cohesive, user-centric features</li>
<li>Contribute to technical decisions around architecture, tooling, and best practices within the team</li>
<li>Take ownership of features end to end, from planning through deployment and monitoring</li>
</ul></li><li>Hands-on AI Implementation</li>
<li><ul><li>Integrate AI-powered coding agents and automated LLM-based testing into your daily development cycle</li>
<li>Contribute to building 'AI-First' UI patterns, working alongside the LLM Platform team on generative, prompt-driven interfaces</li>
<li>Stay current with emerging AI-assisted development tools and bring relevant ones back to the team</li>
</ul></li><li>Project &amp; Execution Management</li>
<li><ul><li>Break down assigned product requirements into clear, actionable engineering tasks</li>
<li>Deliver work reliably within sprint commitments, flagging blockers or scope changes early</li>
<li>Balance new feature delivery with addressing technical debt in the codebase you work on</li>
</ul></li>
</ul><p><b>Requirements</b></p>
<h4 class="jobSectionHeader"><b>
Fullstack Technical Excellence (Core Focus)</b></h4>
<ul><li>5+ years of professional Fullstack development experience with modern JavaScript/TypeScript</li>
<li>Solid expertise in at least one major framework (React, Angular, or Vue) and its ecosystem</li>
<li>Strong understanding of HTML5, CSS3, responsive design, and cross-browser compatibility</li>
<li>Experience building data-heavy UIs, ideally including real-time data visualization</li>
<li>Good grasp of Fullstack performance optimization, including bundle size, rendering, lazy loading, and caching strategies</li>
<li>Experience with state management patterns (Redux, MobX, Zustand, or similar)</li>
<li>Working knowledge of Fullstack testing methodologies, unit, integration, and end-to-end (Jest, Cypress, Playwright, or similar)</li>
<li>Comfortable working with design systems and shared component libraries</li>
<li>Experience using AI-assisted development tools (e.g., Claude Code) to boost engineering productivity</li>
</ul><h4 class="jobSectionHeader"><b>Engineering Maturity</b></h4>

<li>Ability to give and receive constructive feedback through code reviews</li>
<li>Good communication skills, able to explain technical decisions clearly to teammates and stakeholders</li>

<li>Comfortable with ambiguity and rapid change in a fast-paced environment</li>
<li>Thinking in terms of leverage and reuse, not one-off solutions</li>
<li>Pragmatic about trade-offs between perfectionism and speed of delivery</li>
</ul><h4 class="jobSectionHeader"><b>Less About</b></h4>
<ul><li>Developers who prefer working in isolation on narrowly scoped tickets without engaging with the wider product context. We need someone who wants to understand the &quot;why&quot; behind the work and contribute ideas, not just execute tasks.</li>
</ul><h4 class="jobSectionHeader"><b>Nice to Have</b></h4>
<ul><li>Familiarity with ad-tech, real-time bidding platforms, or high-traffic data products</li>

<ul>
<li>Exceptional career growth and learning opportunity</li>

 <br/>
 <br/>
 As a Software Product Engineer, you'll join a focused, deeply skilled team to help build and extend our European open-core integration infrastructure. This includes Hydris: our integrate once, deploy everywhere, open source orchestration plane. Hydris, and its growing ecosystem of partner integrations, are where heterogeneous real-world systems like radars, AIS receivers, mesh radios, satellite feeds, AI analytics, and C2 platforms become one coherent picture, in conditions that are bandwidth-constrained, intermittently connected, and unforgiving.
 <br/>
 <br/>
 <strong>
  What You'll Do
  <br/>
  <br/>
 </strong>
 This role is broad by design. You'll be trusted to take problems end to end: talk to users, shape what gets built, write the code, ship it, see how it performs, and decide what comes next. Day to day that means core engine work on Hydris in Go and TypeScript, extending it with features that genuinely move the field, and helping grow the ecosystem of certified integrations. It also means collaborating across our tech org and helping build and extend our integrated, software-defined customer solutions. And it means setting technical standards: how we test distributed behavior, how we version protocols, and how we keep an API-first product backward compatible.
 <br/>
 <br/>
 <strong>
  Who This Is For
  <br/>
  <br/>
 </strong>
 You build software systems. You've shipped real products that people rely on, and you can show them to us. You care about building the right thing the right way, and about seeing it through. You want to travel when needed or possible, to be with the user, to understand their needs, and build directly to those. And you do your best work where the decisions are meaningful and the problems are challenging. This is a role that will demand the excellence you challenge others to show in their own work and conduct.
 <br/>
 <br/>
 <strong>
  How You Work
  <br/>
  <br/>
 </strong>
 <ul>
  <li>
   Self-starting. You don't wait for a perfectly scoped task; your default is to try something and learn from it.
  </li>
  <li>
   Deeply curious. You'll go down the rabbit hole and come back with something the rest of us didn't know we needed.
  </li>
  <li>
   Builder first. You'd often rather have a rough thing in someone's hands this week than a perfect plan for next quarter.
  </li>
  <li>
   Standard-setting. You join a team to raise its bar. People tend to work a little differently because you're in the room.
   <br/>

   Taken new products from concept to scaling in-market, and lived with the weight of users, edge cases, and keeping it healthy under load.
  </li>
  <li>
   Worked across the full surface: product sense, design instinct, full-stack, deployments, the documentation that empowers other developers, and the long-term maintenance of what you build.
  </li>
  <li>
   Made calls under uncertainty with incomplete information, and owned the outcomes, good and bad.
  </li>
  <li>
   Earned the respect of engineers you respect. The best people you've worked with would take your call.

  <li>
   Built a deep, principled, and broadly applicable skill set through substantial work and study.
