<h1>Role Summary</h1>
<p>We are hiring a <strong>Senior Python Developer</strong> to lead design and implementation across a <strong>stateful, workflow-driven platform built in Python</strong>. This role requires strong backend engineering fundamentals and the ability to work confidently across <strong>application logic, APIs, integrations, asynchronous processing, state management, testing, and production architecture</strong>.</p>
<p>You will work on a platform that combines:</p>
<ul class="simple">
<li>Python services and core runtime design</li>
<li>FastAPI-style HTTP APIs and callback endpoints</li>
<li>Redis-backed state and workflow persistence</li>
<li>Async external-provider integrations and retry handling</li>
<li>Multi-channel messaging backends</li>
<li>LLM-assisted workflow components</li>
<li>End-to-end testing of orchestration, contracts, and recovery paths</li>
</ul>
<p>This is a <strong>senior hands-on engineering role</strong>. We expect <strong>clear technical judgment, strong ownership, and pragmatic architectural decision-making</strong> without unnecessary complexity.</p>
</div>
<div class="section" id="responsibilities">
<h1>Responsibilities</h1>
<ul class="simple">
<li>Design, implement, and maintain <strong>production-grade Python services and runtime components</strong></li>
<li>Own complex backend features <strong>end to end</strong>, from domain modeling through rollout and regression coverage</li>
<li>Build and evolve <strong>stateful workflow systems, orchestration layers, and asynchronous processing</strong></li>
<li>Integrate with third-party APIs and external service providers in a <strong>reliable, observable, and fault-tolerant way</strong></li>
<li>Improve system correctness around <strong>retries, idempotency, error handling, and distributed state transitions</strong></li>
<li>Contribute across the stack including <strong>APIs, integrations, contracts, and tooling</strong></li>
<li>Write <strong>high-signal tests</strong> covering unit, integration, contract, and recovery scenarios</li>
<li>Review code rigorously and raise the bar for <strong>design clarity, maintainability, and runtime safety</strong></li>
<li>Collaborate with stakeholders to turn <strong>ambiguous requirements into robust implementation plans</strong></li>
</ul>

<p>We value engineers who are:</p>
<ul class="simple">
<li><strong>rigorous</strong></li>
<li><strong>pragmatic</strong></li>
<li><strong>comfortable with ownership</strong></li>
<li><strong>concise in communication</strong></li>
<li><strong>capable of handling both systems thinking and implementation detail</strong></li>

<p>If you are strongest only in <strong>isolated backend CRUD development</strong> and do not enjoy <strong>stateful systems, integrations, or workflow complexity</strong>, this role is likely not the right fit.</p>
