Senior full stack engineer

SAEKI — Rebuilding Europe’s industrial backboneEurope'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 program needs parts by next week, your code is how they get them.The RoleAs 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 new HQ in Zurich (Oerlikon), you’ll build:Customer Portal:CAD uploadAutomated quotesOrder managementSecure document exchangeReal‑time trackingFactory OS (ERP/MES):Job schedulingWork order managementOperator interfacesProduction trackingQuality workflowsNote: You do not need defense or manufacturing experience to excel in this role.What You’ll DoBuild and ship customer portal features that defense customers rely on for mission‑critical partsArchitect ERP/MES functionality that operators use to run Factory ONE in GermanySpend time in the factory understanding how your interfaces work under production pressure, then improve themOwn features end‑to‑end – from database schema to API design to frontend implementationWork directly with customers, CAM programmers, and operators to understand their workflowsWhat We’re Looking For5+ years of experience as a software engineer, with a proven track record of shipping production‑ready applicationsTechnical Excellence: Strong command of Type Script, React, and modern backend patterns.
