Software Engineer

Ephos is building vertically integrated, advanced packaging solutions on glass panels. We transform raw glass into electronic and optically active substrates for die-to-die connectivity, manufactured entirely within our own facilities. Our systems are built for companies developing AI accelerators, including hyperscalers and top-tier chip designers.
We have already delivered products to leading global firms, and we are currently building a new fabrication facility to scale production by 100x. This expansion is backed by a $50M EU CHIPS Act grant—the first ever awarded to a startup.
The role
We're scaling from an R&D; cleanroom to a full production fab for photonic integrated circuits, and we're building a new team to match: the group that owns the software, the data, and the AI applied to our manufacturing process. You'll join it from day one.
This team's software runs the core processes of the fab. You'll own projects from pilot through to production in a real industrial environment, where speed and reliability decide whether we win.
And you'll set the standards the rest of the team builds within: technologies, testing, code review, documentation.
Your responsibilities
- Own and evolve our internal and client-facing libraries, with an emphasis on sound architecture and long-term maintainability.
- Build the orchestrator that runs our fabrication lines: the program that coordinates stages, lasers, and sensors, with a GUI for the operators and an API for the manufacturing execution system.
- Set up and help run a ticketing system for engineering requests.
- Write the runbooks and documentation for the key softwares running our manufacturing process.
- Build API and MCP interfaces for integrating our internal tools in a knowledge base.
- Use AI tools to move faster without letting them substitute for real understanding. You should be just as capable of architecting, writing, and reviewing code without them, for it's that grounding that lets you use them effectively.
