About the role

Key responsibilities & impact

Deliver complex features reliably while raising the technical bar of the team
Design and implement complex features end-to-end; own subsystems and navigate existing codebases with architectural discernment, using AI tooling as an accelerant while applying your own judgment on correctness, security, and alignment with the system's direction
Participate in design reviews; propose sound technical designs and identify scalability, performance, and reliability risks before they become incidents
Scope and estimate accurately; deliver features from requirements through rollout and post-release monitoring; communicate risks early
Mentor junior and mid-level engineers through code reviews and pairing; provide substantive feedback that raises the quality of code around you
Drive improvements in team practices — testing patterns, observability, code organization — and push back on shortcuts that create long-term cost
Explain technical decisions clearly to both technical and non-technical stakeholders; represent engineering in product discussions with a security lens
