Java Principal & Senior Software Engineers – Global Fintech (Remote / UK-Based)
We are working with an established global fintech, renowned for delivering world-class payments-related software and technology, to help them grow their UK engineering team. They're on a mission to power the next generation of merchant-first capabilities, and are looking for both Principal and Senior Software Engineers to join them on that journey.
This is a fantastic opportunity to work with a high-performing, autonomous team at the heart of a global payments ecosystem. You will solve real-world challenges at scale, with a strong emphasis on quality, modern engineering practices, and building software that delivers real value.
Why Join?
Engineering-led environment
Our client believes in empowering small, focused teams to make big decisions — and big impact. Engineers are trusted to own outcomes and deliver with autonomy, without unnecessary red tape.
Room to grow
Whether you’re looking to refine your craft, explore new technologies, or step into a more strategic role, you’ll find the support, mentoring, and flexibility to shape your career here.
Everything built here is designed to solve actual problems for merchants around the world, not vanity projects or endless rewrites.
The Opportunity
As a Principal or Senior Software Engineer, you will:
* Design and develop backend services, APIs, and platform features within a modern, cloud-based payments architecture.
* Lead or contribute to projects from inception through deployment, including architecture, testing, and release.
* Build observable, testable systems using best practices such as BDD, CI/CD, and continuous improvement.
* Collaborate with product and engineering teams to ship secure, scalable, and maintainable solutions.
What We're Looking For
We are seeking engineers with:
* 6+ years of professional experience (Senior) or 8–10+ years (Principal) in software engineering roles.
* Strong OO programming skills in one or more languages such as Java, C#, Go, or Ruby.
* Proven experience building server-side applications and integrating with modern APIs and databases.
* Solid understanding of web technologies, SQL, systems integration, caching, and messaging frameworks.
* A self-motivated, collaborative mindset and a desire to mentor and lead (particularly at Principal level).
* The ability to thrive in an agile, outcome-driven environment with varied project scopes.
Why This Role?
* Join a stable, well-funded fintech with global reach and real engineering ambition.
* Be part of a remote-first, UK-based team working on meaningful challenges.
* Influence technology choices and delivery approaches from the ground up.
* Enjoy a culture that blends technical curiosity, pragmatism, and delivery focus.
Interested?
If you're a Senior or Principal Software Engineer ready to take the next step, we would love to tell you more about the long-term vision of this exceptional global fintech client.
