Role Overview

As a Staff Site Reliability Engineer (SRE) on Babylist’s Platform team, you’ll keep Babylist’s infrastructure reliable, fast, and scalable for millions of users.

• Evolve AWS infrastructure and reliability operations across teams with wide leverage
• Drive improvements to Infrastructure as Code (IaC) using Terraform
• Design, improve, and maintain CI/CD systems focused on developer velocity
• Build and tune observability and alerting that is actionable and low-noise
• Lead/participate in on-call and incident management processes
• Operate and debug Kubernetes in production

Requirements

• Deep, hands-on Terraform expertise (own IaC end-to-end)
• Strong AWS experience at scale, including:
  • EKS, RDS, cloud networking, DNS, CDNs, and load balancers
• Experience operating Kubernetes in production (debugging hard issues)
• Comfort designing and improving CI/CD systems (e.g., CircleCI, GitHub Actions)
• Solid observability instincts with tools such as Datadog, Sentry, PagerDuty, Cronitor
• Experience with on-call and incident management
