  • Work closely with engineers, designers, and founders to ship quickly and iterate based on feedback
  • Help define and execute our technical roadmap - balancing technical debt and innovation
  • Invent, improve, and maintain development processes, tools, and workflows
  • Prototype often and move fast - while maintaining high product quality and UX standards

  • Strong proficiency in at least one modern frontend framework - React and Next.js preferred
  • Strong proficiency in Python, and familiarity with at least one Python backend framework (e.g. Django, FastAPI, Flask)
  • Experience with AWS - knowledge of cloud infrastructure and cost/billing concepts is a plus
  • Experience with SQL or NoSQL databases
  • Experience with Docker; container orchestration systems like Kubernetes are a plus
  • Strong communication skills and ability to collaborate effectively with cross-functional teams
  • Enjoys prototyping and experimenting quickly to validate ideas and iterate fast
Required Skills
  • Deep expertise in JavaScript/TypeScript and frontend development
  • Strong architectural understanding of scalable frontend systems
  • Experience integrating with backend APIs and working with real-time or dynamic data
  • Strong product sense and attention to detail - you care how things look and feel
  • Ability to thrive in a fast-paced, ambiguous startup environment and take initiative
  • Ability to work onsite 5 days a week
Bonus Points For
  • Experience at early-stage startups or fast-growth environments (Series A-C, pre-IPO)
  • Passion for developer tools, infrastructure, or cloud platforms
  • Familiarity with Kubernetes or modern DevOps workflows
  • An opinionated eye for clean, simple design and thoughtful UI
Benefits
  • Comprehensive healthcare and dental coverage for you
  • 401(k) plan
