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 Their mission is to remove hidden fees, manual processes, and outdated broker models - their use of AI is pivotal to their mission and the "how".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. You’ll work directly with the founding team to guide technical direction, oversee distributed developers, and play a central role in scaling a platform that’s already transforming the way SMEs handle global payments.
You’ll be joining a small, mission-driven team where autonomy, innovation, and impact are at the heart of everything they do.
What You’ll Do
* Lead and contribute to hands‑on development using Java and Spring Boot.
* Oversee and collaborate with a distributed engineering team (based in Eastern Europe).
* 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?
If you’re an experienced Java Engineer ready to step up into technical leadership or someone who wants to make a real impact in a product‑led FinTech – this is an opportunity to help shape an early‑stage company on the rise.
You’ll work closely with visionary founders, influence the product roadmap, and grow alongside a business that’s backed by strong investment and proven technology.
