Principal Software Engineer - North America [Remote]

The best platforms aren't just built to work today—they're designed to scale gracefully tomorrow.

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 OpsMill, 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.

Why This Role Exists Now

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.

What You'll Be Doing

• 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 customers to build AI-powered automation on Infrahub

• Provide technical leadership through architecture reviews , code reviews, RFC/design doc creation, and mentorship— elevating the entire engineering team's capabilities and decision-making

• Collaborate with Product, Head of Engineering, and CTO to anticipate scaling challenges before they arrive , translating business roadmap into technical strategy and ensuring our software architecture enables rather than constrains product innovation

• Work closely with engineers through implementation phases, ensuring architectural decisions are properly understood and executed while maintaining high velocity and code quality

What You Bring

• 8+ years of backend and platform engineering experience , with a track record of building and scaling complex systems that handle real production load

• Expert-level Python proficiency and deep understanding of writing performant, maintainable code in large codebases

• Experience building developer platforms or tools that other engineers build on top of

• Proven experience designing and scaling distributed systems, including API design, data consistency patterns, and architectural trade-offs at scale

• Track record of leading significant initiatives or platform architecture design, with examples of improving system scalability, reliability, or developer velocity

• Hands-on software architect mindset —you're equally comfortable writing code, reviewing designs, and mentoring engineers to elevate the entire team's technical capabilities

• Strong conviction about AI-first engineering and eagerness to drive its adoption across the team, transforming how we build software and enabling our customers to leverage AI effectively

• Excellent written and verbal communication skills —you can write clear design docs, present technical strategy to leadership, and collaborate effectively across product, engineering, and customer-facing teams

• Self-directed and effective in remote environments with at least 4 hours of overlap with CET timezone (Europe, UK, or US East Coast locations work well)

Nice-to-Haves

• Experience with Rust or Go for performance-critical components

• Hands-on experience with graph databases (Neo4j or similar)

• Background in infrastructure automation, NetDevOps, or network engineering domains

• Contributions to open-source projects or technical communities

Why OpsMill?

• The people: Work alongside world-class engineers who've built and scaled automation platforms in production. Daily technical challenges with smart colleagues who push you to grow.

• The product: Shape Infrahub based on real customer needs. Your input directly influences features, integrations, and roadmap priorities.

• The mission: We're making enterprise-grade infrastructure automation accessible to any organization. Open-source at the core, production-ready out of the box. This is a multi-year journey, not a quarterly sprint.

• The impact: You'll work with teams managing some of the world's most complex infrastructure deployments, solving problems that ripple across entire organizations.

Our Commitment to Diversity and Inclusion

OpsMill is committed to building a diverse and inclusive team. We believe different perspectives make us stronger and more innovative. We encourage applications from candidates of all backgrounds and experiences, and we're committed to providing an inclusive environment where everyone can do their best work.
