About the role
Design, build, and maintain secure, maintainable, self-serve core infrastructure that engineering teams can rely on and operate independently. Lead the architecture and evolution of a modern ML training infrastructure — scalable, reproducible, and built for rapid experimentation.
What they're looking for
- A strong systems thinker who is equally comfortable leading technical direction and getting hands-on with implementation
- 7+ years of software engineering experience, with significant time in infrastructure, platform, or ML systems roles
- Hands-on reliability engineering experience — you have well-formed convictions about observability, monitoring, deployment systems, and loosely coupled architectures, and you've put them into practice at scale
- Proven track record of building and shipping services at scale, with all the operational complexity that comes with it
- Kubernetes — significant production experience building, operating, and scaling Kubernetes clusters
- Experience designing and shipping flexible domain models and APIs — you think carefully about boundaries, contracts, and long-term maintainability
