Staff Software Engineer at Whatnot, a fast-growing livestream shopping platform. This role involves leading the design and evolution of large, distributed systems, owning ambiguous technical problems, and acting as a technical lead for major initiatives. The focus is on building and scaling the core marketplace infrastructure, not directly on AI/ML model development.

What you'd actually do

  1. Lead the design and evolution of large, distributed systems that power live auctions, payments, search, recommendations, trust systems, growth funnels, and more.
  2. Own ambiguous, high-leverage technical problems from inception to production — and set the long-term architectural direction.
  3. Act as the technical lead for major initiatives, driving alignment across multiple teams without formal management authority.
  4. Balance urgency and technical excellence, making principled trade-offs that unlock rapid iteration without sacrificing long-term scalability.
  5. Raise the engineering bar through design reviews, mentorship, and hands-on contributions to critical systems.
