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
Apply DevOps/SRE practices, including CI/CD, infrastructure automation, monitoring, and incident response, to keep platform systems reliable at scale
