Job Description:
Principal Java Software Engineer
London (Hybrid – 1–2 days/week onsite)
? Join a FinTech Powering the Future of Payments
Are you an experienced Senior/Principal Java Software Engineer who thrives in a fast-paced, agile environment? Passionate about high-throughput, real-time systems? This is your opportunity to help shape the core technology that powers instant payments for some of the world’s largest financial institutions.
We’re hiring on behalf of a leading payments consultancy, delivering cutting-edge solutions that integrate seamlessly with bank infrastructure to enable real-time, secure transactions across the globe.
? What You’ll Be Doing
You’ll join a high-performing engineering team building asynchronous, event-driven systems using modern Java technologies.
* Design and build scalable, high-availability systems processing millions of real-time transactions
* Work with Java 17+, Spring WebFlux, AKKA, Kafka, and more
* Write clean, testable code using TDD and BDD
* Contribute to architectural decisions in a fast-evolving codebase
* Collaborate within Agile teams (Kanban/Scrum)
? What You Bring
We’re looking for Engineers who are pragmatic, performance-focused, and thrive on solving complex distributed systems problems.
* Strong hands-on experience with Java 11+ (ideally Java 17)
* Solid knowledge of Reactive Programming (e.g., Spring WebFlux, AKKA)
* Experience with event-driven architecture, real-time messaging systems (Kafka, JMS)
* Familiarity with asynchronous request handling, scalability, and system resilience
* Agile mindset, with TDD/BDD and CI/CD experience
Bonus: Background in Banking/Payments is helpful but not required – if you’ve built high-performance, real-time systems, we want to talk to you.
? What’s In It for You
* ? 20% performance bonus
* ? Work with cutting-edge tech on globally impactful systems
* ? Hybrid working – 1–2 days/week in a London office
* ? Opportunity to collaborate with major global banks
* ? Fast-paced, product-led environment where your voice matters
If you're a motivated Senior/Principal Engineer ready to tackle complex challenges and deliver meaningful change, hit apply – and shape the future of payments with us.
