Principal Software Engineer - Europe

Join us in pushing the boundaries of what’s possible in infrastructure automation

Infrastructure automation is at an inflection point. You can help us push it to the next level. Join the team of engineers and operators building Infrahub, the data layer that automation actually needs.

We’re a fully remote company, and always will be. Work from whatever space makes you happy.

Twice a year, we get together for company offsites to connect and learn together. Each meetup is in a different employee’s home city.

As a fast-growing startup, Ops Mill offers plenty of opportunities to contribute and shape things to come. Jump in as deep as you want.

We reject the ethos of the “startup grind.” World-class results require intensity but not burnout. Like elite athletes, we know that balancing high performance with recovery is the key to sustainable success.

You’ll join a team of seriously smart thinkers and builders who are pushing the limits of what’s possible in infrastructure automation. We welcome your new ideas, curious exploration, and bold approaches too.

You’ll help solve one of the biggest problems in infrastructure automation today, and see global companies with massive networks benefit from your work.

Infrastructure automation is having its moment. Customers are adopting faster, deployments are growing, and the opportunity ahead is massive. But capitalizing on that opportunity requires something many companies struggle with: maintaining software architectural excellence and agility while scaling rapidly. Clean, extensible systems don't happen by accident—they require intentional design, deep technical leadership, and a vision that spans the entire platform.

At Ops Mill, we're building the next generation of infrastructure data management with Infrahub, our open‑source platform that helps automation teams unify data and scale automation reliably. We've achieved product‑market fit, and now we're expanding—new products, growing customer deployments, and increasing demand from the market. This is the exciting phase where the right software architectural decisions compound into sustainable competitive advantage.

Opportunity is knocking, and we need to answer with world‑class engineering. We're building not just one product, but a platform ecosystem—Infrahub, Infrahub Sync, and future innovations that will redefine how automation teams work. We need a technical leader who can architect across this entire platform to ensure systems are extensible and robust, and drive our evolution toward an AI‑first engineering culture.

This isn't about fixing problems—it's about ensuring our software architecture keeps pace with our ambition. We need someone who has scaled complex systems before, who thinks in terms of platforms not just products, and who can guide multiple engineering teams toward technical excellence.

If you're energized by building elegant, scalable software architectures and driving transformational change in how teams leverage AI, this is your opportunity.

• Own the technical software architecture across our platform ecosystem — Infrahub, and future products — to ensure clean, extensible design that scales gracefully with customer growth
• Lead strategic initiatives hands‑on
  , implementing high‑impact architectural improvements to our graph database engine, backend services, and core platform components
• Drive systematic reduction of technical debt by establishing architectural standards
  , identifying areas that will create problems at scale, and guiding the team through thoughtful evolution of the codebase
• Champion and implement AI‑first engineering practices across the team — establishing how we leverage AI in day‑to‑day development, ensuring our codebase and platform work seamlessly with AI tooling, and designing product capabilities that make it easier for…
