What We Do

We build evaluation infrastructure for Voice AI. In just one year since inception, we've partnered with major companies like Google, Doordash, public healthcare companies, public banks, and drive-through fast food chains across five continents to improve their Voice AI agents.

Who We Are

Bluejay is a young startup that has raised $4 million in seed funding from Floodgate, PeakXV, and YC. We're a small team of 10 working towards big goals, handling millions of calls per month and tackling complex engineering challenges at scale.

Location

Our beautiful office, The Sky, is located in Union Square, San Francisco.

Skills We're Looking For

• DevX Optimized developer setup (skills, mcp integrations, worktrees, and immense task parallelization)
• Observability experience (Sentry, Posthog, Grafana, Datadog)
• Backend Python, FastAPI, Supabase, Redis
• AWS (a lot of it)
• Voice AI: LiveKit, Deepgram, Cartesia, ElevenLabs, Gemini, etc
• Websockets, CI/CD chops

Desirable Quirks

• SUPER OPINIONATED about design decisions
• DEEP INTUITION from previous experience designing systems
• optimized developer workflow (what is your workflow for 100x engineering?)

Desirable Experiences

• Has worked at a company that has handled immense scale as an IC or Senior SWE
• Been a technical lead, and handled projects end to end

What You'll Do

• Architect and develop systems that simulate, analyze, and evaluate conversational AI agents, including voice and multimodal systems.
• Design resilient, scalable infrastructure using AWS (Lambda, EC2, Websockets, SIP) to handle millions of real-time conversations.
• Develop algorithms and pipelines that surface insights, detect failure modes, and ensure agents are safe, reliable, and aligned with human intent.
• Work on-site with customers. You'll be building, selling, and deploying the product to real customers.
