Act as the technical leader for reliability for one or more domains; set direction and standards while remaining hands-on where it matters most
Drive reliability strategy across critical services: define SLOs/SLIs, error budgets, and reliability KPIs aligned to customer journeys and outcomes
Own incident response maturity: lead complex incidents, improve incident command practices, and ensure high-quality RCAs with prioritized, tracked remediation
Architect and implement automation to reduce toil and risk: runbook automation, self-service tools, and safe operational workflows (Python + Argo Workflows)
Advance GitOps delivery practices using Argo CD: promotion strategies, progressive delivery/canaries, and guardrails that reduce deploy risk
Scale infrastructure management with Crossplane and Terraform: reusable patterns, policy controls, and paved roads for teams
Lead operational readiness and reliability reviews for new features/architectural changes; reinforce non-functional requirements (availability, latency, security, cost)
Improve performance and cost efficiency through capacity planning, load testing, right-sizing, and architecture recommendations across AWS services
Champion infrastructure security best practices for environments that handle PHI (least privilege, secrets management, auditability, and defense-in-depth)
Mentor Staff and Senior engineers through design reviews, code reviews, pairing, and documentation; raise reliability standards across teams
