Responsibilities
Architect and evolve the Kubernetes platform, service mesh, networking, storage, and CI/CD pipelines; ship golden paths and IaC modules
Define platform SLOs; use error budgets to guide reliability vs. velocity trade‑offs; drive incident learning and readiness reviews
Improve developer velocity (build/deploy times, flaky tests, local dev ergonomics) with measurable results
Lead capacity planning and commitments; build guardrails for cost, security, and compliance with Security/FinOps partners
Write high‑impact code, automation, and tooling; mentor across teams and raise the bar on operational excellence
Embed AI in the developer experience—from code generation to observability and incident response—so teams ship faster and safer by default
Qualification
Required
10+ years building and operating cloud platforms (compute, networking, storage, runtimes like Kubernetes), with a track record of multi‑region HA and SLO rigor
Deep in Kubernetes, service mesh, Terraform/IaC, CI/CD, and production observability; you ship golden paths and guardrails that lift the whole org
Experience with databases and storage systems, including SQL and NoSQL databases, and object, block, or file storage platforms
You've brought AI into platform engineering—from copilot‑assisted workflows and intelligent test generation to AIOps for incident triage, anomaly detection, and runbook automation—with clear security and cost boundaries
You lead via design reviews, incident excellence, and SLO/error‑budget tradeoffs communicated in business terms
You're hands‑on with AI tools and help teams adopt them responsibly
Preferred
Core SLOs & velocity: ≥99.95% SLOs for core services; 25–50% faster build/deploy times; developer‑reported friction trending down
AI‑enabled platform: Approved AI tooling is integrated into IDE/CI/CD with repo policies and auditability; ≥70% MAU among eligible engineers; MTTR down 20–30% via AI‑assisted triage; flaky‑test rate decreases through targeted, AI‑suggested fixes
Guardrails in place: Cost, security, and compliance controls are codified as IaC modules and enforced in paved roads
Experience with enterprise governance, including compliance and audit requirements
Familiarity with GDPR and data privacy considerations in large-scale, production environments
