Full Stack Engineer (Founding Team)

The Role: Full Stack Engineer (Founding Team)

Location: Bangalore (on-site)

About the Company

InCommon is hiring on behalf of a seed-stage consumer fintech building an AI-first personal finance app for India - a premium, conversational alternative to the dashboard products that dominate the category. The thesis is that most people dont deploy their money well, not because the information is missing, but because its buried in charts that assume you already know what to look for. The product reads a users full financial context and tells them what matters, proactively.

Youll own the system end to end - from the data coming in to the interface the user touches. The most important piece is the user context layer: the engine that assembles a complete picture of a users finances from what they tell us directly and from what we pull via account aggregators, MF Central, and other APIs. Everything the product knows flows through what you build.

This is a founding-team seat. Youre not joining a platform team inside a larger org - youre building the platform.

What youll do

• Build the user context layer: user-provided data plus integrations with account aggregators, MF Central, and mutual fund platforms
• Own the backend in Python and FastAPI
• Build and extend the frontend in React / React Native, shipping to web and iOS from one codebase
• Instrument the product with telemetry - funnels, behavioral data, the works so the team can see whats actually happening, not guess
• Own deployment, uptime, and security posture

What were looking for

• 3 - 6 years spanning backend and frontend, with real depth on at least one side
• Strong in Python/FastAPI and React
• Zero-to-one experience - youve built something before the patterns existed, in a small team where you owned outcomes rather than a slice of a system
• Comfort owning infra directly: EC2, keeping services up, basic security hygiene, no dedicated DevOps team to lean on
• Bonus: youve set up telemetry/observability from scratch and can talk about what you tracked and why
• Bonus: React Native - if youre strong in React were confident youll pick it up
• No fintech or finance-domain background required

Process note: the interview includes a machine coding round — youll build something real, live. If you do your best work heads-down rather than on the clock, worth knowing going in
