Senior Frontend Developer (React Native)

We are looking for a senior frontend developer to lead the build of our customer-facing mobile experience. You will own the React Native application end-to-end - architecture, performance, release pipeline, and the user experience that millions of pounds of customer activity will eventually flow through. You will work closely with the senior leadership and our backend engineers on the Microsoft stack to design clean, secure APIs and deliver features that feel fast and trustworthy.

What You Will Do

• Lead the frontend development of our React Native mobile app (iOS and Android)
• Own the mobile build, release, and crash-monitoring pipeline
• Design and integrate APIs with our .NET / C# backend services
• Drive code quality through reviews, pairing, and pragmatic standards
• Collaborate with product and design on UX, performance, and accessibility
• Mentor mid-level engineers as the team grows
• Contribute to backend work where it makes sense - we value full stack instincts

• 5+ years of professional software development, with strong frontend ownership
• Deep React Native experience shipping production iOS and Android apps
• Strong TypeScript and modern React (hooks, state management, testing)
• Experience designing and consuming RESTful APIs
• Experience with mobile CI/CD (App Store / Play Store, code signing, OTA updates)

Nice to Have

• Experience in fintech, lending, payments, banking, or other regulated environments
• Solid working knowledge of the Microsoft backend stack - C#, .NET / ASP.NET Core, SQL Server
• Comfortable owning features end-to-end across the stack
• Azure experience (App Service, Functions, Service Bus, Key Vault)
• Experience with biometric auth, secure storage, and mobile security best practice

About You

• You take ownership - you do not wait to be told what to do
• You care about craft: performance, accessibility, and details users feel
• You communicate clearly with engineers, product, and non-technical stakeholders
• You lift others up - code review, pairing, and mentorship come naturally
