CONTRACT - Senior / Staff / Principal Software Engineers | UK Challenger Bank | Liverpool St | 2-days on site | Outside IR35
We're working with an established UK Challenger Bank entering a significant scale-up phase and looking for exceptional talent to level-up the engineering org.
We're not looking for people with "X years in Y language", we want to speak to systems thinkers who care about scalable architecture, continuous deployment, clean code, business value and user experience - regardless of whether your background is Java, Go, Python, Kotlin, .NET, TypeScript, Data or anything else.
- Product-Minded: You don't just build to spec; you care about why you’re building it and the value it adds to the customer.
- Engineering Maturity: You understand TDD, CI/CD, and how to build resilient distributed systems.
- Collaboration: You enjoy mentoring, peer-reviewing, and raising the bar for an entire engineering organisation.
- Tech-Agnostic: You’re comfortable working across the stack or even moving into new domains (Fullstack, Data, or Platform).
Interested? We aren't looking for a perfect CV match; we’re looking for great engineers. If you’re tired of being boxed in by a specific language and want to work on complex, high-scale problems, please apply and let’s talk.
