Founding Engineer — Backend, Data & Infrastructure
Bangalore (Hybrid) or Remote within India · Full-Time · Reports to Founder/CTO

We're an early-stage B2B SaaS company. The MVP is built and running. You're the first full time engineer, and you'll own everything from the data ingestion layer to what ships to production.
This is not a role where you get handed tickets. You'll be deciding what gets built, how it gets built, and whether it's ready to go live.

WHERE THINGS STAND TODAY

The core product logic works. The database schema is designed and running on PostgreSQL. The FastAPI backend is scaffolded with async architecture. CSV ingestion is functional. The frontend is deployed.

What's missing is the layer between "it works on my machine" and "a paying customer depends on this." That's your mandate.

You are not starting from zero, and you are not inheriting a legacy mess. You're inheriting a working prototype that needs an engineer who knows what production actually means.

WHAT YOU'LL OWN

▸ BACKEND & API




Take the existing FastAPI + PostgreSQL codebase to production standard. Structured logging, proper error handling, a test suite that actually catches regressions, and monitoring that tells us when something breaks before a customer does. Build and maintain the REST APIs serving the frontend, with low-latency responses on table and drill-down queries.

▸ DATA ENGINEERING
Design and build the ETL layer. Ingest from third-party APIs and file uploads, transform, normalize into our core schema, and load reliably. Handle the unglamorous parts properly: schema drift, partial syncs, duplicate records, timezone mismatches, and data that arrives malformed because someone's CRM has a custom field nobody documented.

▸ INTEGRATIONS
Own third-party connectors end to end — CRM, accounting, and ad platforms. OAuth flows, token refresh, rate limit handling, sync scheduling, retry logic, and failure recovery that doesn't require a human to notice. Every connector needs a CSV
