Requirements

What you’ll need

8+ years of software / infrastructure engineering experience; 4+ years in a senior IC or technical leadership role on a Platform, SRE, or DevOps team.
Deep expertise running production systems on a major cloud provider (AWS, GCP, or Azure).
Hands-on with Kubernetes, infrastructure-as-code (Terraform, Pulumi, or similar), and modern CI/CD tooling (GitHub Actions, ArgoCD, Spinnaker, etc.).
Strong programming skills in at least one of Go, Python, or TypeScript — you build tooling, not just configure it.
Demonstrated experience scaling infrastructure through a significant growth inflection (10x users, new product surface, architectural migration) in a production environment.
Proven track record designing for high availability, zero-downtime releases, and graceful degradation in regulated or data-intensive environments.
Strong security fundamentals: IAM, secrets management, network segmentation, vulnerability management, supply-chain security.
Experience at an early-stage or high-growth startup where you owned infrastructure broadly, not just a narrow slice.
Excellent written and verbal communication — you're equally effective in a post-mortem, a roadmap discussion, and a Slack thread.
