Jobbeschreibung

Overview

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.

The Role

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.

What We're Looking For

• 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). Comfortable with PostgreSQL optimization and API design.
• End-to-End Ownership: You own features from database schema to API design to frontend implementation. You don't wait for someone else to handle "the other half."
• Technical Agency: Comfortable making decisions with minimal supervision. You have a passion for building interfaces that solve complex user workflows.
• First Principles Thinker: You reason by physics and economics, not analogy.
• Industrial Grit: Comfortable spending time on the shop floor in Germany to see how your software interacts with precision machinery.
• Maniacal Urgency: You understand that speed is our only edge. You thrive in the "chaos-to-order" phase of a startup.
• On-site: Ability to work in-person at our HQ in Zurich, Switzerland.

What we're not looking for

- Engineers who only work on frontend or only work on backend. You must be comfortable across the full stack.
- People who need detailed specs before they start building. You'll work directly with users and define the solution yourself.
- Developers who ship code and move on. You own the outcome — not just the PR.
- Engineers who are uncomfortable with ambiguity or rapidly changing priorities.

What we offer

• Mission: Rebuild the industrial sovereignty of the West. Your work directly enables the production of mission-critical hardware for defense and space.
• Total Ownership: High-stakes autonomy in your domain. You own both the problems and the solutions — and have the authority to execute.
• The Environment: Access to a 5,000m² state-of-the-art facility featuring 5-axis CNCs, industrial robots, and industrial 3D printers. Your work runs on real hardware from day one.
• The Team: "Special Forces" model. Everyone senior, everyone ships. No politics, no bureaucracy. Direct feedback, high standards.
• Compensation: Competitive salary + meaningful equity.
• Location: Zurich HQ or Factory ONE in Munich, depending on role. Hybrid options available where applicable.

Apply

• Resume: Focus on systems you've built and owned.
• GitHub/Portfolio: Show us work you're proud of — code, machines, or production systems.
• Cover letter: Why this mission? Why now? What would you build first?
