Build a better way to borrow

Fig is a Canadian fintech making personal lending simpler, faster, and more accessible for Canadians. We offer fully digital personal loans, helping customers apply in minutes and receive decisions quickly, without paperwork, branch visits, or long delays .

Since launching in 2023, we’ve grown quickly and earned recognition including Consumer Lender of the Year and FinTech Startup of the Year. We’re proud to be consistently ranked among Canada’s Best Workplaces, with a 4.8/5 Trustpilot rating from our customers.

Supported by Fairstone Bank of Canada and Ontario Teachers’ Pension Plan, we combine deep lending expertise with the agility of a startup.

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.

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.

• Partner with Design to build a shared component library and a polished, consistent user experience.

• Use AI tools and agents to accelerate how we build, test, and ship.

• Raise the bar through code review, testing practices, and mentoring other engineers.

• Daily use of AI coding tools, with the judgment to review and validate what they produce.
