• Work with colleagues to meet compliance obligations and card scheme requirements.
• Integrate third‑party services and manage the technical challenges of connected payments systems.
• Shape architecture decisions and establish engineering standards.
• Collaborate with platform engineers to improve CI/CD pipelines and provide fast development feedback.
• Guide the team’s use of AI coding tools.
• Own features through design, development, testing, deployment and ongoing support.
• Work closely with product, design and the wider engineering team.

What we’re looking for

• At least eight years’ commercial software development experience.
• Strong development experience with Java, Kotlin or Scala.
• Experience building asynchronous, event‑driven systems.
• A track record of mentoring and supporting small engineering teams.
• Strong database experience, using technologies such as PostgreSQL, MySQL, SQL Server, DynamoDB or Cosmos DB.
• Experience integrating third‑party services.
• Regular use of AI coding tools within an enterprise production development workflow.
• Strong knowledge of automated testing, version control, CI/CD and secure coding.
• Confidence taking ownership and making technical decisions in an early‑stage environment.
• An interest in fintech, payments or improving access to financial services.

Desirable experience

• Designing, developing and supporting payment processing platforms.
• Building new platforms from the ground up.
• Working in banking, fintech or another regulated sector.
• Cloud development using AWS, Azure or GCP.
• Containers and infrastructure as code.
• Establishing engineering practices within a growing team.
