• 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 orchestration, stream processing, real-time systems, analytics, and content understanding
