Role overview
The DevX Platform as a Service team is hiring a Senior Software Engineer. The DevX PaaS team builds and operates CarGurus' Kubernetes-based developer platform that enables product teams to ship quickly, reliably, and at scale. We're a sub‑team within Developer Experience in Engineering Platform, partnering across engineering to remove friction, modernize our stack, and accelerate time‑to‑market.
What you'll do

• Design, build, and operate the Kubernetes platform on AWS EKS with a focus on reliability, security, and developer ergonomics (multi‑env, multi‑region).
• Advance our Controller/Operator and deployment model to provide consistent, self‑service delivery across repositories and environments.
• Lead critical upgrades and rollouts: Kubernetes, Rancher, and routine add‑on upgrades utilizing ArgoCD and HCP Terraform.
• Drive autoscaling and cost/performance wins by partnering with product teams to adopt autoscaling practices and supporting policies/templates that balance efficiency and performance.
• Raise platform reliability by hardening alerting/runbooks and participating in our on‑call rotation with sensible, business‑hours expectations and documented handoffs.
• Explore and implement service connectivity improvements (e.g., service discovery/mesh) to simplify developer configuration and reduce operational toil.

What you'll bring

• 4+ years of experience working as a Software Engineer in a professional setting
• Proficiency with containerization and cloud environments.
• Deep Kubernetes/EKS experience operating production workloads at scale.
• Strong Go (or equivalent) systems programming skills; familiarity with controller/operator patterns is a plus.
• AWS fluency across core primitives (networking, IAM, load balancing, storage) and platform guardrails.
• Infrastructure as Code experience (Terraform, Helm, ArgoCD, GitHub‑based workflows) and CI/CD automation.
• Observability and SRE mindset: metrics, tracing, logging, SLOs, incident response, and post‑incident learning.
• Security‑by‑default bent: policy‑as‑code (e.g., Kyverno), least‑privilege, image/runtime controls.
• Developer empathy and clear communication; you enjoy building paved roads that hundreds of engineers can rely on.
