  • Own frontend architecture and engineering practices
  • Set visual standards through shared components and interaction polish
  • Design interactions for long-running generation, editing, media payloads, and real-time inference
  • Improve performance for media processing and user-perceived latency
  • Work across frontend, API, database, and migration layers
  • Work with research, infrastructure, growth, and design to prioritize work
