About the Company

A fast-growing startup building simulation, observability and self-improvement tooling for voice AI agents, used by major consumer, healthcare and financial brands and handling millions of calls a month.

The Role

  • Build algorithms and pipelines that surface insights, detect failure modes and keep agents safe and aligned.
  • Own your work fully, across the stack.
  • Work on-site with customers to deploy the product.

What You Bring

  • 1+ years of experience
  • Proficiency across the stack, especially databases, AWS and AI engineering
  • Obsessive attention to detail and the ability to lead technical execution
  • An exceptional signal: a strong bachelor's degree and/or experience at a top fast-growing startup
  • Strong, personable communication for customer-facing work
  • Ability to work in person in San Francisco 5 days a week

Nice to Have

  • High-traffic features built at scale
  • A highly optimized AI-assisted developer workflow
  • Technical lead experience
