Senior Member of Technical Staff

What You'll Do

• Own the core AI infrastructure.
  • LLM orchestration, prompt management, retrieval systems, structured output parsing.
• Design agent architecture.
  • Define the abstractions that let the team ship new agents in days.
• Build evaluation systems.
  • Systems that measure whether agents are actually getting better at closing deals — not whether the demo passed.
• Architect decision-trace capture.
  • Make every AI judgment traceable, so the system can learn from its own history.
• Own platform scale.
  • Thousands of concurrent conversations, sub-second response times.

What We're Looking For

• 3+ years building software, with a track record of owning systems end-to-end — owned, not contributed to; you got paged when it broke.
• You architect and implement; you've built AI systems in production (LLM applications, agent frameworks, RAG, voice).
• You write code with AI (Cursor, Claude Code) and run multiple sessions at once.
• Strong architectural judgment paired with hands-on implementation.
• Bonus: voice or real-time systems; agent frameworks or evaluation systems; prior startup experience.

The Reality

• On-site in San Francisco, in person, long days, high standards.
• The trade for the intensity is rare: you make architectural decisions that stick, you ship without a consensus gauntlet, and founders will actually listen to you.
• The right person reads the pace as the point.

Logistics

• Location: San Francisco, in-office.
• Based here or willing to relocate.
• Benefits: Uber commuter benefits; breakfast, lunch, and dinner provided; snacks and coffee stocked; free gym membership; health, dental, and vision.
• Process: 15-min founder call → Super Day on-site (technical phone screen first if you're outside SF).
• To apply: Send your resume and tell us about a system you've owned end-to-end.
• Compensation Range: $175K - $350K
