Lead AWS Infra Architect for AI Agent Platform

Runta; San Mateo (CA); Hybrid; USD 180,000 - 240,000; Full time

Job summary

Runta is building the execution layer for AI agents. We’re a small, well-funded team in the San Francisco Bay Area and Singapore, focused on reliable runtime infrastructure, scalable compute, and governed execution.

As our infrastructure lead, you’ll own production AWS platforms, design cross-cloud abstractions, and drive IaC with Terraform to keep the platform reproducible and cost-efficient. You’ll shape the roadmap with the founder and work across teams to deliver resilient infrastructure.

Qualifications

• You’ve designed and operated production AWS infrastructure you were accountable for.
• 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 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.
