ph3Overview /h3pEurope's defense industrial base cannot respond at the speed modern conflict requires.

When a critical defense program needs parts by next week, your code is how they get them. /ph3The Role /h3pAs a Senior Full Stack Engineer on our Platform team, you'll own development of our customer portal and ERP/MES systems — the interface between our Manufacturing Intelligence stack and the humans who use it.

You'll architect features from customer CAD upload to real-time order tracking to operator work instructions. /ppBased at our HQ in Zurich (Oerlikon), you'll build: /pullibCustomer Portal: /b CAD upload, automated quoting, order management, secure document exchange, real-time production tracking. /lilibFactory OS (ERP/MES): /b Job scheduling, work order management, operator interfaces, production dashboards, quality workflows. /liliemNote: You do not need defense or manufacturing experience to excel in this role. /em /li /ulh3What We're Looking For /h3ullib5+ years of experience /b as a software engineer with a proven track record of shipping production-ready applications. /lilibTechnical Excellence: /b Strong command of TypeScript, React, and modern backend patterns (Go, Python, or Rust).

Your work runs on real hardware from day one. /lilibThe Team: /b "Special Forces" model. Tribal knowledge is retiring. Supply chains are fragile.

SAEKI is building the operating system for autonomous factories — the infrastructure that lets Europe manufacture mission-critical components at software speed. /ppYou'll build the customer-facing portal and factory operating system features that connect our customers to our factory.

Comfortable with PostgreSQL optimization and API design. /lilibEnd-to-End Ownership: /b You own features from database schema to API design to frontend implementation.

You thrive in the "chaos-to-order" phase of a startup. /lilibOn-site: /b Ability to work in-person at our HQ in Zurich, Switzerland. /li /ulh3What we're not looking for /h3p- Engineers who only work on frontend or only work on backend. You must be comfortable across the full stack.br/- People who need detailed specs before they start building.

You'll work directly with users and define the solution yourself.br/- Developers who ship code and move on. You own the outcome — not just the PR.br/- Engineers who are uncomfortable with ambiguity or rapidly changing priorities. /ph3What we offer /h3ullibMission: /b Rebuild the industrial sovereignty of the West.

Your work directly enables the production of mission-critical hardware for defense and space. /lilibTotal Ownership: /b High-stakes autonomy in your domain.

You own both the problems and the solutions — and have the authority to execute. /lilibThe Environment: /b Access to a 5,000m² state-of-the-art facility featuring 5-axis CNCs, industrial robots, and industrial 3D printers. Everyone senior, everyone ships. No politics, no bureaucracy.

Hybrid options available where applicable. /li /ulh3Apply /h3ullibResume: /b Focus on systems you've built and owned. /lilibGitHub/Portfolio: /b Show us work you're proud of — code, machines, or production systems. /lilibCover letter: /b Why this mission? Why now? What would you build first? /li /ul /p #J-18808-Ljbffr
