Are you a senior/lead hands-on Engineer who thrives in Payments environments? Do you have a background in building low-latency, high-throughput distributed systems where correctness, resilience, and performance really matter?
This is a great opportunity to work with some of the world's leading Banks on their real-time payments infrastructure. The ideal person will have a background working on SWIFT, ISO 2002, Open Banking, PSD2, BACS, CHAPS, etc.
What You’ll Be Doing
- You’ll work directly with some of the world's leading banks in their high-performing engineering teams, building asynchronous, message-driven systems designed for scale, resilience, and near-zero downtime.
- Design and implement high-throughput, low-latency systems processing millions of real-time payment events.
- Build event-driven architectures using modern Java and reactive frameworks.
- Work extensively with non-blocking I/O, asynchronous flows, back-pressure, and concurrency.
- Contribute to system and API design, focusing on scalability, fault tolerance, and observability.
- Collaborate closely with architects, engineers, and client teams across Europe.
- Operate in Agile environments (Scrum / Kanban) with a strong engineering culture.
Tech Stack (current & evolving):
- Java 17+, Spring WebFlux, Akka, MongoDB, Kafka, reactive streams, distributed messaging, cloud-native tooling.
What You Bring
- Strong hands-on experience with Java 11+ (ideally Java 17) in production environments.
- Deep understanding of asynchronous and reactive programming models.
- Proven experience with event-driven architectures and real-time messaging (Kafka, JMS, Akka, etc.).
- Solid grasp of distributed systems concepts: concurrency, idempotency, fault tolerance, and resilience.
- Experience building and testing production-grade systems using TDD/BDD and CI/CD pipelines.
- Comfortable working on complex, long-lived systems where performance and reliability are critical.
- NoSQL experience, ideally MongoDB.
Bonus (not essential):
- Experience in banking, payments, or financial systems, or if you’ve built real-time platforms at scale.
What’s In It for You
- £90,000 – £115,000 base salary (DOE).
- 20% annual bonus.
- Work on event-driven, real-time systems with global impact.
- Hybrid working – 1 day a week onsite (more if you prefer).
- Exposure to major international banks and payment networks.
- A product-led, engineering-first environment where technical decisions matter.
