Qualification
Proven AWS experience at scale — EKSHow You Will Make An Impact
Required
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.
How You Will Make An Impact
Infrastructure ownership — manage and evolve our AWS environment using Terraform, keeping EKS clusters, databases, and core services current, performant, and secure
