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, or infrastructure — with meaningful time operating production systems at scale Deep IaC expertise — you design Terraform architectures, not just write modules; you've managed complex state and multi-account configurations in production Strong GitOps background — you understand declarative infrastructure management at depth and have opinions on how to do it well Deep Kubernetes knowledge — you've operated clusters in production, dealt with real failure modes, and understand the system at the control plane level Strong AWS background — networking, compute, IAM, storage, multi-account design Experience with multi-tenant infrastructure — isolation patterns, noisy neighbor mitigation, and tenant lifecycle management Automation-first thinking at a senior level — you design systems that eliminate entire categories of manual work, not just individual tasks Active user of agentic coding tools — you know how to direct them effectively, review their output critically, and use them to multiply your output Reliability engineering track record — SLOs defined and measured, post-mortems run, measurable improvements driven Strong communicator — you can make architectural decisions legible to engineers and leadership alike NICE TO HAVE Experience with Karpenter and node lifecycle management in production Background in FinOps — cost attribution, reserved capacity planning, workload right-sizing Familiarity with data infrastructure — object storage, CDC pipelines, or lakehouse patterns Experience supporting AI/ML inference workloads or GPU-based compute in production Prior experience scaling platform infrastructure at a startup moving toward enterprise-grade requirements WHAT YOU WON'T FIND HERE A platform team that maintains the status quo. We're actively building — new scale requirements, new architectural domains, new automation capabilities. Senior engineers here shape how the platform evolves, and the tools available to do it are better than they've ever been.
