About your role We're looking for a Senior Site Reliability Engineer II to help us scale our infrastructure and reliability practices as we grow our engineering org by 90+ people this year. You'll take ownership of reliability and observability for your team's systems, work hands-on across Kubernetes, AWS, and CI/CD, and partner with 16+ engineering teams to roll out standards and automation that reduce friction org-wide. This role is for someone who's proactive by nature — you see a problem and go fix it without waiting to be asked. You're comfortable working across teams with different workflows and priorities, and you're already using AI tools as part of how you build, debug, and ship. You won't be working in a vacuum: you'll partner with a Staff-level architect and engineering leadership on the biggest calls, while owning execution and cross-team rollout yourself. What you’ll do Own reliability and observability across the organization — SLAs/SLOs, instrumentation, and on-call health Design, deploy, and maintain Kubernetes infrastructure (Helm, EKS/ECS) and core AWS services (RDS/Aurora Postgres, networking, scaling) Build and maintain CI/CD pipelines in GitHub Actions and Argo/Helm Drive adoption of Infrastructure as Code standards (Terraform, and increasingly Crossplane) across multiple teams Partner with 16+ engineering teams to roll out new standards, tools, and processes — adapting the rollout to how each team actually works Participate in on-call rotation and lead incident response/root-cause analysis for issues that cross team boundaries Use AI tools daily to work faster and more effectively, and help less AI-fluent teammates pick up the same habits Represent SRE's perspective in planning conversations with engineering leadership
