Job Description

A global payments technology platform is re-architecting how money moves in real time, building highly resilient, event-driven systems that operate at scale and power critical financial flows worldwide. This role sits within a core engineering team responsible for designing and delivering backend services that make intelligent, time-sensitive decisions about how money moves across a global network. The systems are event-driven, highly distributed, and business-critical, requiring strong engineering discipline and pragmatic architectural thinking.

Job Responsibility

  • Designing and building backend services that sit at the heart of a large-scale financial platform
  • Developing Java-based services that support real-time decision-making and high-throughput processing
  • Ensuring systems are observable, resilient, and performant
  • Collaborating with engineers, product partners, and stakeholders to turn business requirements into robust technical solutions
  • Contributing to improvements in testing, deployment, and overall engineering quality

Requirements

  • Strong backend engineering experience with Java in production environments
  • Experience building and operating distributed systems at scale
  • Practical exposure to event-driven or streaming architectures
  • Comfort working in cloud-native environments (AWS or similar)
  • A quality-first mindset: testing, reliability, and maintainability matter to you
  • Ability to work autonomously while collaborating effectively within a team
  • Clear communication skills and confidence working with both technical and non-technical stakeholders

What we offer

  • Ownership of critical systems with genuine business impact
  • A modern stack and the opportunity to influence how systems evolve
  • Visibility, autonomy, and support within a mature engineering organisation
  • Hybrid working with a London-based engineering team
