Senior Platform & Site Reliability Engineer

Responsibilities:

• 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 the platform.
• 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.
• 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, and OOM kills so engineers are only paged for genuinely novel failures.
• Deployment standards: release management, rollback mechanisms, and canary and blue-green patterns where justified.
• 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, and known rollback patterns. Novel or ambiguous failures escalate to a human with full context attached.
• 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.
• Target: full platform integration within a defined window per acquisition.

Requirements:

• 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 a 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 is strongly preferred.
