• Own platform initiatives end-to-end: scope, design, build, ship, and maintain
• Drive systems design for new integration infrastructure, including services, queues, data pipelines, async workflows
• Lead projects staffed with junior and mid-level engineers; make them measurably more productive through code review, design feedback, and the systems you build
• Identify and eliminate classes of problems rather than patching individual one off bugs
• Set technical direction in ambiguous problem spaces
• Collaborate closely with IE and adjacent teams to ensure platform primitives meet real consumer needs
