If you’re a strong mobile engineer who wants more than incremental app feature work, this is a chance to build a high-performance FinTech product at the core of a real trading and financial systems platform. We’re working with a rapidly scaling startup building technology in partnership with an established hedge fund. They’re creating a new engineering hub in Newcastle, and mobile is a key interface into the platform. This isn’t a typical “marketing app” or CRUD mobile build. You’ll be working on a real-time, data-heavy mobile product that surfaces trading, risk, and financial decisioning tools used in live environments. The business is well-funded, already commercially validated, and early enough that the mobile stack, architecture, and UX patterns are still being actively defined. This is a genuine opportunity to shape the product from the ground up.
What you’ll be doing:
- You’ll take ownership of mobile experiences end-to-end across iOS and cross-platform development.
- Building and maintaining high-performance mobile applications in Swift (iOS), Flutter, or React Native.
- Designing scalable mobile architecture for a real-time, data-intensive FinTech product.
- Integrating complex backend systems (trading, risk, analytics, and pricing data).
- Working closely with backend engineers and quants to surface complex financial information in a clear, usable way.
- Making key decisions around mobile architecture, performance, and UX.
- Helping define mobile engineering standards and best practices in a scaling team.
Tech environment:
- iOS (Swift) for native development.
- Flutter and/or React Native for cross-platform mobile development.
- API-driven, real-time data systems.
- Exposure to distributed backend / FinTech systems.
- Strong engineering fundamentals over framework preference.
Why Newcastle?
- This is a full-time onsite role (Mon–Fri) in brand-new central Newcastle offices.
- The environment is designed for focus and high-quality engineering: Modern offices with city and countryside views.
- Strong social engineering culture (many recent relocations).
- Walk/cycle-friendly location with onsite facilities.
- Stable working hours (09:00–18:00) with flexibility where needed.
- Strong relocation support for UK-based candidates.
What they’re looking for:
- We’re looking for strong mobile engineers who care about building polished, performant products across platforms.
- Strong experience in mobile development (iOS / Flutter / React Native).
- Proven track record shipping production mobile apps.
- Strong understanding of mobile architecture patterns (state management, modular design, etc.).
- Experience working with complex APIs and real-time data.
- Strong Computer Science fundamentals (OOP, data structures, algorithms, design patterns).
- Product-minded engineer who cares about performance and UX.
- Comfortable working in a small, fast-moving engineering team shaping a platform from early stage.
Package:
- Salary up to £120,000+ (flexible for exceptional candidates).
- Bonus.
- 25 days holiday.
- Private healthcare (Bupa).
- Pension contribution.
- Strong career progression in a scaling FinTech platform.
