Senior Platform & Site Reliability Engineer (Remote)

What You Will Own Platform Architecture Full architectural ownership of the non-AWS toolchain: CI/CD, observability, event streaming, automation, secrets, and deployment infrastructure Define, build, and enforce platform standards across portfolio products Terraform IaC for all infrastructure — nothing provisioned manually, everything versioned and reviewed Self-service developer platform so product teams ship without waiting on platform Event Streaming & Pipeline Infrastructure Own the event streaming architecture, operational standards, and health monitoring across all products using real-time pipelines Design and maintain batch processing infrastructure alongside live event flows Ensure pipeline reliability, throughput, and cost are actively managed at scale CI/CD & Deployment Build and maintain CI/CD pipelines (GitHub Actions) across all portfolio products Automate triage and retry logic for known failure classes — flaky tests, dependency timeouts, OOM kills — so engineers are only paged for genuinely novel failures Deployment standards: release management, rollback mechanisms, canary and blue-green patterns where justified Observability & Reliability Own the full observability stack: Grafana, Prometheus, and Loki across all products SLOs and error budgets defined per product; reliability tracked consistently Build alerting that correlates signals and surfaces diagnostic context alongside notifications — so on-call engineers arrive at an incident with hypotheses, not a blank screen Incident response: on-call design, escalation playbooks, post-mortem facilitation Automated remediation scoped to a defined set of safe, idempotent actions — container restarts, ECS task scaling, known rollback patterns. Novel or ambiguous failures escalate to a human with full context attached Acquisition Onboarding Platform audit and gap analysis for every new acquisition — assessing CI/CD maturity, IaC coverage, observability gaps, and security posture Migration plan and execution for each portfolio company joining the platform. Target: full platform integration within a defined window per acquisition What We're Looking For Experience & Background 8–12 years in platform engineering, DevOps, or SRE — with clear evidence of increasing ownership over time Strong Terraform depth across multi-environment, multi-account setups CI/CD ownership across a multi-product environment with GitHub Actions Experience with event streaming infrastructure at production scale — design, operations, reliability, and cost management Hands-on Grafana, Prometheus, and Loki in production AWS operational depth: ECS, EKS, RDS, IAM, VPC, CloudWatch, Cost Explorer SRE fundamentals: SLOs, error budgets, on-call design, post-mortem culture Acquisition or greenfield platform integration experience strongly preferred
