Software Developer (Backend-leaning, Full-stack)

About us

callSaul is an AI phone receptionist for small businesses — it answers calls, books jobs and

captures leads so owners don't miss work. Built by Trikuti AI Labs. Small team, early stage, live

product.

What you'll work on

• Internal admin tools — phone number provisioning, tenant management
• Customer-facing settings screens (React + TypeScript)
• Scheduled jobs — data retention, cleanup, reports
• Third-party integrations — payments, calendars, CRMs, telephony APIs
• Moving file storage from local disk to object storage
• Monitoring and alerting, so we find out something broke before the customer tells us
• Writing tests. We have a real test suite and we intend to keep it

Must have

• Python and FastAPI (or Django / Flask, if you're happy to switch)
• PostgreSQL — you can write a join and reason about a schema
• React and TypeScript — enough to build a working admin screen
• Docker
• Git, and you've worked somewhere code gets reviewed
• You've shipped something to production and debugged it when it broke

Nice to have

Any of these is a bonus. None are expected.

• Voice, telephony or real-time audio — WebSockets, media streaming, Twilio / Telnyx /

Exotel

• Speech or AI APIs — speech-to-text, text-to-speech, LLM integrations
• Supabase, Alembic, GitHub Actions
• Webhooks and third-party API integrations
• Background jobs and queues

How we work

Small team. You'll have real ownership of your area and talk to the founder directly. Code is

reviewed before it merges. We move quickly, but we don't ship to production on a Friday

evening.
