- Lead the buildout and evolution of our Flink platform, helping drive stream processing from early platform investment to production-ready usage across the company.
- Design scalable, reliable, multi-tenant streaming infrastructure rather than simply building pipelines on top of an existing platform.
- Own core platform concerns including scalability, performance, reliability, SLOs, and operational excellence for stream processing systems.
- Build high-quality systems that support real-time analytics, event-driven applications, and machine learning infrastructure needs across Whatnot.
- Make key decisions about how data systems should be integrated across Whatnot, and then partner cross-functionally to bring that architecture to life
- Collaborate closely with engineering partners across product, platform, machine learning, and data to enable fast, safe, and scalable development
- Help shape broader company architecture across stream processing, real-time systems, analytics, and content understanding

- Hands-on experience designing and operating stateful real-time data pipelines at scale, including concepts like checkpointing, state management, and watermarking.
- Experience evaluating architectural tradeoffs in stream processing systems, including when Flink is the right solution and when it is not.
