About Ephos
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 need someone to design and build the network and OT infrastructure from the ground up.
You'll be one of the first hires on a new team, the group that owns the software, the data, and the infrastructure behind everything we manufacture. Much of what you build will be specified before the building is even finished. That's the nature of the role: you'll define how our fab network,
line-control systems, and IT/OT boundary work, with the freedom to choose the right tools and vendors rather than inherit someone else's stack.
This is a hands-on, high-ownership role. If you care about engineering velocity, rock-solid networking, best-in-class security, and building something that has to run reliably from day one of production, there's a lot here to dig into.
Responsibilities
• Design the new production Fab network from scratch: architect a segmented network following OT security best practices (e.g. NIST 800-82), dimension and select the switches, access points, and firewalls the new facility needs, and evaluate vendors beyond what we use today.
• Set-up an SD-WAN with multiple ISPs, connect our two locations into a single reliable network, and ensure the whole stack survives failures of single elements (switches, firewalls, or ISP).
• Build and run the infrastructure the
