Senior Mobile Engineer (React Native)

London | Fintech | Early-stage, real traction

3 days in office

No sponsorship available

This isn’t a side mobile app – It’s the product.

We’re working with a small London-based fintech building a mobile-first platform.

Already live with enterprise customers and thousands of users, and now moving into the next phase of growth.

What’s interesting here

• You’re building the core mobile experience, not supporting it
• Real users, real usage, real scale (and growing fast)
• Early enough to shape the product and technical direction
• Backed by a leadership team that’s built trading systems and scaled startups before

The role

• Owning and building features in a React Native mobile app
• Improving performance, reliability, and user experience as usage scales
• Working closely with product to shape what gets built, not just deliver it
• Supporting some web work (React) where needed
• Helping take the product from thousands → tens of thousands of users

What they’re looking for

• Strong experience with React Native
• Background in startup or scale-up environments
• Engineers who are comfortable with ambiguity and moving fast
• Product-minded – you care about the end user, not just the code
• People who take ownership and want to build something properly

Environment

• Low ego, high ownership
