Responsibilities
Strategic Leadership: You will influence the product roadmap in collaboration with Product, Design, and Engineering, while helping to drive team-wide goals, planning, and feedback cycles
Technical Standards: You will author code that sets the standard for quality and velocity for the team, frequently establishing patterns that other teams can effectively contribute to
Navigating Ambiguity: You will thrive in ambiguity, often identifying and offering solutions to problems, like framework migrations or rendering bottlenecks, that are not yet evident to the leaders who presented them
System Health: You will efficiently use and improve our infrastructure to reduce cost, load, downtime, and incidents, navigating trade-offs to ensure the healthy progress of the codebase. This includes optimizing the “Boot” lifecycle and managing API reliability through request deduplication and rate-limiting
Mentorship & Culture: You will build a safe space for learning and serve as a skilled and trusted mentor to engineers across the organization, developing the ability to coach new leaders rather than just individual contributors
Cross-Functional Execution: You will collaborate with teammates across engineering to identify, define, and solve strategically important initiatives, acting as a leader in communication to de-escalate conflicts and drive consensus
Qualification

7+ years of experience writing client-side code (React + Typescript) for modern web applications at scale
Experience working in a large-scale, shared codebase with hundreds of contributors, where you have successfully established patterns that allow other teams to contribute effectively without friction
Expertise in building complex systems and tooling, with the ability to lead technical design that guides the best decisions across the team
Exceptional communication skills with the ability to tie technical infrastructure your work succinctly to company goals like performance, reliability and developer velocity

A commitment to proactively offering regular, constructive feedback and gracefully receiving it to improve yourself and the team culture
