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
