About the role

Role on the Data Platform team building real-time data systems, streaming infrastructure, and multi-tenant streaming platforms to support real-time analytics, event-driven apps, and ML infrastructure at Whatnot.

Responsibilities

  • Define technical direction and lead development of critical data platform systems that power next-generation capabilities at Whatnot
  • 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

Qualifications

  • 5+ years of experience
  • Ability to write well-tested, API-driven applications and services that run at scale in production
  • Track record of building scalable, high-performance distributed systems
  • Strong experience with streaming data systems such as Kafka, Flink, or Pulsar, with particular strength in building or evolving the platform layer itself — not just downstream pipelines
  • 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
  • Experience building multi-tenant or end-to-end streaming infrastructure that supports multiple teams or production use cases
  • Expertise in managing cloud data stores (Snowflake, BigQuery, Redshift, etc.) for processing and serving data products
  • Strong experience supporting operational systems to ensure uptime, reliability, and maintainability, including monitoring, alerting, and incident management
