The Company

WeDo is working with a global fintech organisation operating at significant scale within the payments space. The business builds and runs mission‑critical platforms responsible for safeguarding, moving, and optimising money for enterprise customers worldwide. Engineering teams are trusted with a high degree of autonomy and play a direct role in shaping both technical and strategic direction.

The Position

This is a senior‑level role within the Treasury Engineering function, focused on building and evolving the systems that manage the company’s money. The domain spans safeguarding requirements, capital optimisation, and ensuring liquidity is available at the right time. You will join a highly autonomous team working on largely green‑field initiatives with clear visibility at a strategic level. The environment follows a genuine “you build it, you run it” model, with engineers owning architecture, platform pipelines, and the full software development lifecycle end to end.

The role offers a balance between hands‑on engineering and driving technical initiatives across the team. You will influence architectural decisions, contribute to cross‑team projects, and help shape how the platform evolves, while remaining firmly embedded as an individual contributor. This role suits senior engineers who want meaningful influence, architectural ownership, and a strong understanding of the business impact of their work, without stepping into people management.

Requirements

• Strong backend engineering experience using Java and Spring Boot
• Proven experience working with event‑driven architectures and Kafka
• Experience designing and operating systems in AWS environments
• Exposure to services such as RDS, Aurora, or Flink
• Experience with Kubernetes and containerised platforms
• Ability to lead technical initiatives and influence architecture beyond your immediate team
• Comfortable working with high autonomy and ownership
• Curious, product‑minded engineers who want to understand the business context behind technical decisions
