About The Position

Bluejay builds the simulation, observability and self-improvement layer for Voice AI agents. Within a year of launch, Google, DoorDash, public healthcare companies, public banks, drive-through chains and enterprises on five continents use it, and it handles millions of calls a month. Founders Faraz and Rohan built infrastructure for Microsoft Copilot and AWS Bedrock before starting Bluejay. The company raised a $4M seed in 2025 from Floodgate, Peak XV and Y Combinator, has sustained seven-figure revenue since, and is a team of about 10 in Union Square, San Francisco.
