Principal Engineer / Engineering Lead — Agentic AI

ppAre you a deeply hands-on senior engineer who wants to own the technical core of a frontier AI product — architecting, reviewing and shipping code, not just running a team? /ppOur client is a fast-growing Zurich-based B2B AI software company and Microsoft partner, building agentic AI that executes business processes end-to-end — software agents that don't just assist, but carry work through to a finished, human-approved result.

As they scale the platform, they're bringing in a very senior engineering leader to take operational and technical ownership of the product — effectively much of what a CTO owns, with the freedom to stay hands-on. /ph3What you'll own /h3ulliEnd-to-end architecture of an agentic platform on Azure, and the critical engineering decisions behind it /liliDesign and orchestration of multi-agent systems and artefact generation across the product /liliProduction-grade reliability — evaluation, regression and observability, so agent behaviour is measurable and dependable /liliBackend services on Azure, plus contributions to the React/TypeScript front-end (including approval/audit UI) /liliEngineering standards (code review, CI, modular AI components, connectors) — raising the bar across a small, high-calibre team /liliThis is a hands-on individual-contributor / tech-lead role.

People management is deliberately secondary: you architect, review and code. /li /ulh3What you bring /h3ulliSubstantial software engineering experience at senior / staff / principal level, with a track record of building and operating production systems /liliHands-on experience with production AI / agent systems — real users, real traffic, real failure modes (chat wrappers alone aren't enough) /liliExperience designing and orchestrating multi-agent systems /liliFluency with modern AI/agent tooling — orchestration frameworks, evaluation pipelines, MCP-style connectors, Azure AI Foundry /liliEnglish fluent (working language); German a plus, not a must /li /ulh3Why this role /h3ulliA frontier mission — a genuine autonomous-execution platform, not a chatbot wrapper /liliCTO-level scope and ownership of the technical core, without title politics /liliMeaningful equity participation for strong

profiles — real upside, not a token /liliA strong Microsoft / Azure foundation and ecosystem to build on /liliDirect access to the founders and leadership, short decision paths, fast execution /liliA small, high-calibre team where your decisions matter — central Zurich location by the lake; international, English-speaking /li /ul /p
