Payments Engineer
London – Hybrid (1 day per week onsite)
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 worlds 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 worlds 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
We’re looking for engineers who enjoy thinking in events, streams, and asynchronous workflows, and who take pride in building systems that perform under pressure.
- 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 are 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
