About this job

<p><strong>As a Pirate</strong></p> <p>We’re not looking for a software engineer who works through tickets. We’re looking for someone who can identify, board, and take over a merchant vessel in record time, and who leaves behind a ship where every knot is flawless. AI now handles much of the design, prototyping, and coding. What matters is building fast without leaving chaos behind. Concretely:</p> <ul> <li>Design thinking — you understand the actual problem before writing a single line of code</li> <li>Rapid prototyping with AI — you don’t treat modern AI tools as a novelty but as a core part of your workflow, going from idea to working prototype in hours instead of weeks</li> <li>Agentic coding with a firm hand — you let agents code for you, but you keep them on a short leash: strict architecture guidelines, clean design patterns, no sprawl</li> <li>Speed with foresight — you build fast, but you’re already thinking two releases ahead. Every important design decision is documented and traceable, even when you built at sprint speed</li> </ul> <p><strong>As an Architect</strong></p> <p>Once the vessel is taken, you take command. Now structure matters more than speed.</p> <ul> <li>Software & feature blueprinting — the plan exists before the building starts</li> <li>Systems engineering — you think in systems, not isolated components</li> <li>Software engineering design patterns — core toolkit, not bonus knowledge</li> <li>Architecture design — you make and own the big decisions, and you know when a microservice earns its keep and when it's just overhead</li> <li>Cloud-native product architecture — you design products for the cloud, not applications that happen to run there</li> <li>Code reviews — held to a high standard, but constructive</li> <li>Extreme attention to structure — loose ends are not a minor offense to you</li> <li>Broad foundation across databases, data structures, storage, cloud functions, and infrastructure as code — you choose deliberately, not out of habit</li> </ul> <h2>Tasks</h2> <p>The work itself, concretely:</p> <ul> <li>Building and maintaining AI agentic workflows — on industry-standard frameworks, with the same architectural discipline you would apply to any other production system</li> <li>Building and maintaining data processing pipelines — ingestion, transformation and enrichment of customer data: reliable, observable, and safe to reprocess</li> <li>Shipping features end to end — the <strong>React</strong> screen, the <strong>Python</strong> service behind it, and the <strong>AWS</strong> infrastructure it runs on</li> <li>Making quality measurable — evaluation sets, tracing, and budgets for latency and cost, so a regression is caught by us and not by a customer</li> <li>Integrating with our customers’ systems — real business data from real enterprise landscapes, rarely clean and never twice the same</li> </ul> <h2>Requirements</h2> <ul> <li>Multiple years of experience as a software engineer, ideally with ownership of architecture decisions</li> <li>Practical, current experience with AI-assisted development (not just “tried it once”)</li> <li>Understanding of cloud native architecture, ideally on AWS</li> <li>End-to-end reach — ideally you are at home in the frontend, the backend and the infrastructure, and can take a feature all the way to production without handing it over at every boundary</li> <li>The rare combination: high speed AND high structural discipline</li> <li>Strong communication skills to explain and defend architecture decisions — including to agents that “wanted to solve it differently”</li> </ul> <h2>Benefits</h2> <p>✨ Shape and own the technical architecture as the company scales</p> <p>✨ Work within a modern, AI-driven engineering setup</p> <p>✨ High level of autonomy and real impact from day one</p> <p>✨ Dynamic, entrepreneurial environment with room to grow</p> <p>Send us resume / portfolio / GitHub / an example of a project you recently built using an AI-assisted workflow</p> <p><strong><em>No cover letter needed. Just show us you can board and clean up.</em></strong></p><p>Find more <a href="https://www.arbeitnow.ch/english-speaking-jobs">English Speaking Jobs in Switzerland</a> on Arbeitnow</a>
