Senior Platform Engineer / SRE

THE ROLE We're looking for a Senior Platform Engineer / SRE who can work with complex infrastructure work, drive IaC and GitOps architecture, and set the standard for how we automate and operate systems at scale. You'll tackle hard problems — multi-tenant isolation, self-service infrastructure, reliability engineering — and have the scope to solve them properly. This is not a ticket-processing role. Seniors here identify problems before they're asked, make architectural calls, mentor engineers, and raise the ceiling on what the platform can do. WHAT YOU'LL WORK ON • IaC architecture — Terraform module design, state management, multi-account patterns, and setting the standards the rest of the team builds against • Drive GitOps at scale — ArgoCD configuration, progressive delivery patterns, promotion workflows, and deployment reliability across multiple environments and tenants • Architect and operate multi-tenant Kubernetes infrastructure on AWS EKS — tenant isolation, workload placement, cluster topology, and long-term scalability strategy • Build self-service infrastructure automation — provisioning pipelines, configuration management, and platform capabilities that engineering teams can consume without manual intervention • Agentic coding tools for infrastructure work — scaffolding new environments, generating and reviewing IaC, accelerating automation, and establishing patterns for the team • Own reliability — SLO definitions, error budgets, incident response quality, and the feedback loop that turns incidents into platform improvements • Set observability standards — trace coverage, alert quality, on-call ergonomics, and runbook culture • Partner with security on zero-trust architecture, secrets management at scale, and infrastructure hardening • Contribute to technical roadmap and help the team prioritize the right work • Mentor mid-level engineers — code review, design feedback, on-call shadowing WHAT WE'RE LOOKING FOR • 6+ years in platform engineering, SRE,
