We are working with an established global fintech, renowned for delivering world-class payments technology, as they grow their UK engineering team. They're powering the next generation of merchant-first capabilities and are looking for a Senior Software Engineer to join them on this journey.

This is a fantastic opportunity to work with a high-performing, autonomous team at the heart of a global payments ecosystem. You’ll tackle real-world challenges at scale, with a strong emphasis on quality, modern engineering practices, and building software that delivers lasting value.

The Opportunity

As a 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 cross-functional teams to ship secure, scalable, and maintainable solutions.
Mentor junior engineers and lead by example, fostering a culture of learning and growth.

What We’re Looking For

We are seeking engineers with:

6+ years of professional experience in software engineering roles.
Deep expertise in object-oriented design and architecture, with the ability to apply design patterns in scalable and maintainable ways.
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 collaborative, self-motivated mindset and a desire to mentor and support the growth of others.
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.
