Your work will have CISO-level visibility and shape how tens of thousands of Amazon builders design and operate their services.
You're a senior software engineer with deep expertise in distributed systems, security, and large-scale design. You deliver complex initiatives independently, make sound technical decisions with broad impact, and mentor engineers at multiple levels. You write exemplary code, conduct insightful code reviews that raise the quality bar, and debug complex issues across multiple systems. You communicate technical concepts clearly to diverse audiences and demonstrate leadership beyond assigned tasks. You influence technical direction and drive consensus on complex decisions.
