  • Proven experience building and maintaining backend services and APIs

  • Solid understanding of relational databases and data modeling

  • Experience deploying and operating applications in cloud environments

  • Ability to work independently and take ownership of projects

  • Prior experience in a startup or fast-moving product team is a plus

Compensation & Benefits
  • Base Salary: $160,000 – $210,000 (San Francisco senior-level range)

  • Equity: Competitive equity package

  • Benefits: Medical, dental, vision coverage; flexible PTO; standard startup benefits
