Senior Full Stack Engineer

Europe's defense industrial base cannot respond at the speed modern conflict requires. Legacy suppliers operate on month-long timelines. 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.You'll build the customer-facing portal and factory operating system features that connect our customers to our factory. When a critical defense program needs parts by next week, your code is how they get them.As 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.Based at our HQ in Zurich (Oerlikon), you'll build:Customer Portal: CAD upload, automated quoting, order management, secure document exchange, real-time production tracking.Factory OS (ERP/MES): Job scheduling, work order management, operator interfaces, production dashboards, quality workflows.Note: You do not need defense or manufacturing experience to excel in this role.5+ years of experience as a software engineer with a proven track record of shipping production-ready applications.Technical Excellence: Strong command of TypeScript, React, and modern backend patterns (Go, Python, or Rust).
