CallMissed
Careers

Build AI communication for India

We're a small, fast-moving team shipping WhatsApp agents, voice IVR, and OpenAI-compatible APIs. Remote-first across India — we care about what you ship, not where you sit.

Why CallMissed

Real production impact

Your code serves live B2C businesses — fintech, e-commerce, healthcare, edtech — across India.

End-to-end ownership

Small team means you own features from API design to dashboard UI to deploy — not ticket queues.

Modern stack only

FastAPI, PostgreSQL, Next.js 16, React 19, Tailwind v4, Docker on AWS. No legacy migrations.

Remote-first

HQ in Pune. Work from anywhere in India. Async-friendly with clear written communication.

Open roles

Internships

Hands-on internships aligned with our tech stack. All roles are remote within India.
