Join a Fast-Growing FinTech Revolutionising Payments
We’re partnering with a venture-backed FinTech start-up that’s redefining how businesses manage international payments and currency conversion. Their mission is to remove hidden fees, manual processes, and outdated broker models - their use of AI is pivotal to their mission and the "how".
The business is now looking to hire a hands-on Senior Java Developer to help scale their platform and shape the next phase of growth.
The Opportunity
This is a rare chance to join a well-funded, product-led start-up at a pivotal point in its journey.

* Own and evolve the technical architecture across AWS and Kubernetes infrastructure.
* Build, enhance, and maintain integrations with FX and payments APIs.
* Work closely with the founders to define technical roadmaps and delivery milestones.
* Ensure engineering excellence through code reviews, best practices, and mentoring.
What We’re Looking For
* 5+ years’ experience in Java development, ideally with strong Spring Boot knowledge.
* Proven experience working with Kubernetes and AWS.
* Prior exposure to Currency Cloud APIs or similar payment/FX API integrations is highly desirable.
* Comfortable working in a fast-paced, start-up environment with limited structure and high autonomy.
* Able to balance hands-on coding with technical leadership.
* Excellent communication skills and a proactive, ownership-driven mindset.
* Experience in FinTech or payments is a major plus.
What’s in It for You
* £50,000–£80,000 base salary (DOE).
* EMI stock options (10% company-wide pool) with significant upside potential.
* Full-time, remote-first flexibility - work from anywhere (UK hours preferred).
* Opportunity to join a venture-backed business at a truly exciting growth stage.
* A culture built on trust, transparency, and work-life balance.
The Tech Stack
* Backend: Java, Spring Boot
* Infrastructure: AWS, Kubernetes
* APIs: Currency Cloud (and similar FX/payment APIs)
* Tools: GitHub, Slack, AI-driven automation tools
Why Apply?
