Staff Engineer, Site Reliability

Babylist is hiring a Staff Site Reliability Engineer for its Platform team. The role owns and evolves infrastructure and reliability practices, with a focus on security engineering, AWS, CI systems, and developer tooling supporting the company’s products and engineering teams.

Responsibilities:

• Infrastructure ownership — manage and evolve our AWS environment using Terraform, keeping EKS clusters, databases, and core services current, performant, and secure
• Software and automation — ship tested tools and services with runbooks and self-service workflows that other engineers can adopt and operate
• Secure infrastructure defaults — build versioned, tested Terraform modules for least-privilege access, secrets, and workload isolation, with automated checks for configuration drift
• CI/CD reliability — keep delivery fast and dependable across Engineering, integrating dependency and container scanning, secret detection, and short-lived deployment credentials
• Developer support — be the person engineers turn to when environments break; unblock them fast across local, staging, and production
• Monitoring & alerting standards — define service-level objectives (SLOs) and actionable alerting with engineering teams, using incident trends to prioritize reliability improvements
• Recovery readiness — validate backups, restore procedures, and failover paths through regular recovery tests
• Incident response — lead or support incident response, drive post-incident reviews, and close the loop so the same thing doesn't happen twice
• Platform strategy — shape our long-term infrastructure roadmap and lead cross-team initiatives from design through rollout, adoption, and ongoing operation, mentoring engineers along the way

Requirements:

• Strong software engineering skills
• you've shipped and operated production-quality tools or services, with tests, code review, and maintainable interfaces
• Experience building security into production systems
• you've personally designed, implemented, and operated controls for access, workload identity, secrets, or network isolation
• Deep hands-on Terraform expertise
• you own IaC, not just contribute to it
• Proven AWS experience at scale — EKS, RDS, cloud networking, DNS, CDNs, load balancers — you know the gotchas
• Experienced operating Kubernetes in production
• you've debugged the hard stuff, not just deployed the easy stuff
• Comfortable designing and improving CI/CD systems — CircleCI, GitHub Actions, or similar; you care about developer velocity, not just pipeline uptime
• Strong observability instincts — Datadog, Sentry, PagerDuty, Cronitor — you build alerting that's actionable, not noisy
• Experienced with on-call and incident management
• you've run the post-mortems and actually changed things afterward
• Comfortable supporting developers across local, staging, and production — you're a resource, not a gatekeeper
• You naturally reach for AI in your work — at Babylist, every team uses AI daily. You're already using it to move faster and improve your output, and you stay curious about what's coming next
