Senior Cloud Infra Engineer — Terraform & Multi-Cloud

Runta; San Francisco (CA); On-site; USD 180,000 - 240,000; Full time

Job summary

Runta in the SF Bay Area is seeking a Senior Infrastructure Engineer to design and operate production AWS infrastructure, owning the IaC layer with Terraform, and shaping cross-cloud architecture.

You will drive cost-aware decisions, manage state at scale, and build abstractions that keep multi-cloud on the table while not over-engineering.

This ownership role requires deep systems fundamentals and hands-on leadership, reporting directly to the founder and collaborating with runtime teams.

Qualifications

• You’ve designed and operated production AWS infrastructure you were accountable for, not just worked within someone else’s.
• Deep Terraform (or equivalent IaC) experience: complex modules built for other engineers to consume, state management at scale, infra CI/CD.
• Multi-cloud or cross-cloud experience: provider-spanning abstractions, workload migrations, or internal platforms built on IaC.
• Experience running serverless or container platforms at scale (Lambda, Fargate, ECS, EKS).
• A cost-optimization track record you can talk through in specifics: RI strategy, Spot fleet design, rightsizing with real numbers.
• Solid distributed systems fundamentals: consistency models, replication, consensus.
• You understand orchestration platforms at the why level, not just the kubectl level.

Responsibilities

• Design and operate Runta’s production infrastructure on AWS: compute, networking, storage, observability
• Own the IaC layer: Terraform modules, state management, CI/CD for infrastructure changes
• Design cross-cloud abstractions that don’t lock us into a single provider
• Own the infrastructure side of snapshot/resume/branch: snapshot graph storage, control plane / data plane separation, local cloud state consistency
• Make cost-aware architecture decisions: instance strategy, Spot fleet design, storage tiering, rightsizing
• Shape the infrastructure roadmap as an early technical leader, working directly with the founder
