About the role

Fig is expanding beyond lending and building a new generation of digital banking products. We're hiring a Senior Mobile Engineer, reporting to the Engineering Manager of our digital banking team, to build and own the Fig banking app on iOS and Android.

You're a React Native specialist with deep experience shipping production apps, from developer tooling through to release pipelines. You're comfortable across the stack in TypeScript, having built backend services and designed APIs for mobile clients.

Our core stack includes TypeScript, NestJS, React Native (Expo), React, PostgreSQL, and AWS. We use AI for software development and are moving toward more agentic ways of working. We want engineers who'll help shape how we get there.

We're a small team, so breadth matters. You'll work closely with Product, Design, Risk, Compliance, and Operations, and help set the mobile patterns, tooling, and quality bar as we grow.
