SAEKI — Rebuilding Europe’s industrial backbone

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 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 new HQ in Zurich (Oerlikon), you'll build:

Customer Portal: CAD upload, automated quotes, order management, secure document exchange, real-time tracking

Factory OS (ERP/MES): Job scheduling, work order management, operator interfaces, production tracking, quality workflows

Note: You do not need defense or manufacturing experience to excel in this role

What You'll Do

• Build and ship customer portal features that defense customers rely on for mission-critical parts
• Architect ERP/MES functionality that operators use to run Factory ONE in Germany
• Spend time in the factory understanding how your interfaces work under production pressure, then improve them
• Own features end-to-end - from database schema to API design to frontend implementation
• Work directly with customers, CAM programmers, and operators to understand their workflows
  
  

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. Comfortable with PostgreSQL optimization and API design.
• Technical Agency: You are comfortable making decisions with minimal supervision and have a passion for building interfaces that solve complex user workflows.
• Impact-Driven: You understand how technical decisions in Zurich impact the operators and machines on the shop floor in Germany.
• Adaptability: You thrive in a constantly evolving environment with dynamic objectives and enjoy iterating directly with users to solve "ground truth" problems.
• Continuous Learning: You have the ability to quickly master new technologies and industrial concepts even without prior experience.
• Maniacal Urgency: You understand that speed is our only edge. You thrive in the "chaos-to-order" phase of a startup.
• First Principles Thinker: You don't reason by analogy. You reason by physics and economics. You calculate the "Idiot Index" of every feature before you build it.
• Industrial Grit: You are comfortable spending time on the shop floor in Germany to see how your software interacts with 50-ton machines.
• Ability to work in-person at our HQ in Zurich, Switzerland.
  
  

Life at SAEKI

• Mission: Rebuild Europe's industrial backbone. Your code enables defense programs.
• Impact: Own features that determine whether parts ship in weeks or months.
• Growth: Opportunity to lead projects and potentially build a team as the company scales.
• Team: "Special Forces" model. Everyone senior, everyone ships. Direct feedback, high standards.
• Compensation: Competitive salary + meaningful equity at a Series A company with defense traction.
• Location: Zurich HQ (required) with hybrid options (typically 1-2 days WFH per week).
