Remote Staff NA Platform Engineer Terraform Kustomize

Requirements

• IaC Discipline: Strong Terraform and GitOps/Kustomize practice, with a bias for making operations idempotent, automated, and self-verifying. • IaC Discipline: • Incident Judgment: Real incident-response experience on distributed-systems failures — databases, streaming, consumer lag, data integrity. • Incident Judgment: • Data Systems Fluency: You know how Postgres, a columnar store, and a log/streaming bus behave under load. • Data Systems Fluency: • Agent Fluency: Comfort working alongside AI agents — writing the guardrails, runbooks, and checks that let automation operate safely, and knowing where a human must stay in the loop. • Agent Fluency: • Instincts: You reach for "encode this as a check" before "I'll remember to do this." You'd rather delete a manual step than document it. You treat a wrong runbook as a production bug. • Instincts:

Responsibilities

• System & Platform Design: Own infra topology, scaling and blast-radius boundaries, the build/deploy graph, database ownership boundaries, and cost ceilings — the decisions agents execute but can't make. • System & Platform Design: • Guardrail Engineering: Build the validation gates, idempotency checks, drift detectors, and runbooks that keep both humans and agents from doing damage. Your deliverable is the safety system, not the deploy. • Guardrail Engineering: • Escalation Tier: Diagnose the novel failures — consumer lag, DLQs, materialized-view chains, consent ordering. Write the runbook the first time; agents handle it after. • Escalation Tier: • Reliability, Capacity & Cost: Own the 500K events/sec target: load testing, Karpenter/HPA tuning, Database sizing, SLOs and alerting. • Reliability, Capacity & Cost: • Security & Secrets Boundary: Own IAM/IRSA, secret rotation, the auth chain, and what the agent/MCP surface is allowed to do. • Security & Secrets Boundary: • Agent-Fleet Operability: Keep skills, runbooks, and agent context in sync with reality. A stale runbook is a wrong actor, executed confidently. • Agent-Fleet Operability: • Incident Leadership: Lead incidents and capture every fix as a new runbook plus regression test. • Incident Leadership:
