📋 Description

• Set technical direction: Own the architecture and high-level design for new services and critical system evolutions, ensuring scalability, observability, and fault tolerance. • Embrace cradle-to-grave stewardship: craft the design, guide it through delivery, and stand behind it in production, continuously validating with SLIs/SLOs and blameless post-mortems. • Lead by example: Deliver production code daily—primarily in Node.js/TypeScript—and champion best practices in testing, CI/CD, documentation, and incident response. • Mentor & multiply: Coach senior and mid-level engineers, provide actionable feedback, and foster a culture of learning, psychological safety, and engineering excellence.
