About us
We're a Manchester-based FinTech building a smarter way for tenants to pay rent. Our platform pays landlords the full rent on time and collects smaller instalments from tenants via Open Banking Variable Recurring Payments (VRP). We're a small, high-trust engineering team solving genuinely hard problems in payments, credit, and financial correctness — where getting the maths and the money movement exactly right matters.
The role
We're looking for a Senior Full Stack Developer to own features end-to-end across our .NET backend and React Native mobile client. You'll work close to the domain — instalment maths, double-entry ledgers, scheduled money movement, and third-party integrations with banking and identity providers. This is a hands-on senior role with real ownership and influence over architecture.
What you'll work with
- Backend: .NET 10 / C#, EF Core (SQL Server), a service-oriented solution with clean domain boundaries
- Async & messaging: MassTransit, background workers, durable/idempotent scheduled jobs
- Cloud & platform: Azure, .NET Aspire, containerised services
- Mobile: Expo / React Native (TypeScript)
- Integrations: Open Banking, VRP, BaaS, identity verification, credit decisioning
- Practices: ADR-driven architecture, EF Core migrations, automated testing (MSTest, NSubstitute, FluentAssertions)
What you'll do
- Design and ship features spanning the C# backend and the React Native app
- Model financial domains carefully — money, fees, timing differences, ledgers — where precision is non-negotiable
- Build resilient, idempotent background processing for payment execution and scheduling
- Integrate with external banking, payments, and identity providers
- Contribute to architectural decisions
What we are looking for
- Strong commercial experience with C# / .NET and modern TypeScript
- Solid EF Core / relational database skills (SQL Server ideal)
- Experience building and consuming APIs, and working with asynchronous/message-based systems
- React Native (Expo) experience, or strong React skills and appetite to work across mobile
- A pragmatic, quality-first mindset — you care about correctness, testing, and clear design
- Bonus: FinTech / payments / Open Banking experience, cloud (Azure), event-driven architecture
Benefits
- £65k–£85k salary depending on experience
- Hybrid working from our Manchester office
- 25 days holiday + bank holidays
- Pension, and the chance to shape a product (and a team) from an early stage
- Meaningful ownership and a direct line to the impact of your work
- Sound like you? Apply with your CV and a short note on something you've built that you're proud of.
Pay: £65,000.00-£85,000.00 per year
