• Design, build, and ship production-grade systems end-to-end - frontend, backend, infrastructure, and the operational glue in between - on time, on budget, and at high quality. • Own technical decisions on architecture, cloud topology, observability, deployment, and security for the projects you lead. • Write secure, resilient, well-tested code, and hold the bar on code review for the people you work alongside. • Debug hard problems - production incidents, performance regressions, concurrency bugs, distributed systems weirdness - and write up what you learn so the team gets stronger. • Build prototypes and proofs of concept to learn quickly (hours, not days), validate ideas, and de-risk technical decisions before committing to a direction. • Mentor teammates and serve as the rubber duck for tougher technical problems. Make the people around you better. • Research new technologies and tools and contribute to refining team processes and engineering practices to deliver excellence. • Provide rough effort estimates and technical scope on new opportunities, and occasionally help present technical options to client stakeholders.
