- Set standards for reliability, security, observability, and operability, including SLOs, production readiness, and incident review.
- Stay hands-on: build prototypes and critical components, and lead resolution of the hardest production issues.
- Identify systemic technical debt and platform risks, and drive plans to address them, including build-vs-buy decisions.
- Mentor senior and staff engineers, help set the hiring bar, and establish engineering culture for the Seattle team.
- Partner with Product, Security, and engineering leadership to align the platform roadmap with business priorities.
