Are you passionate about building scalable, resilient systems in the fast-moving world of FinTech?

We’re looking for a Senior Backend Engineer to join our growing technology team. You’ll play a key role in designing and building backend services that power our core platform — enabling real-time transactions, intelligent routing, and seamless third-party integrations with partners across the financial ecosystem.

You’ll work with a modern tech stack - including Java Spring Boot, PostgreSQL, Redis, AWS Lambda, and a wide range of AWS services — and collaborate closely with engineers, product managers, and stakeholders to deliver reliable, high-performance systems.

If you thrive in a collaborative, fast-paced environment and enjoy solving complex engineering challenges, this could be a great fit.

WHAT YOU'LL BE DOING

• Design, develop, and maintain backend services (utilising Java Spring Boot), contributing to the evolution of our platform and system architecture.
• Optimise backend systems for real-time processing, performance, resilience, and scalability to meet the demands of a growing, enterprise customer base.
• Implement integrations with third-party systems, ensuring secure and reliable data exchange across environments.
• Participate in the full software delivery lifecycle — from requirements gathering to production deployment and ongoing support.
• Troubleshoot production issues and contribute to a culture of operational excellence and continuous improvement.
• Collaborate closely with product managers, designers, and fellow engineers to ensure technical solutions align with business objectives.
• Provide high-quality code reviews and mentor junior engineers where appropriate.
• Contribute to infrastructure and DevOps best practices, including CI/CD pipelines and containerised deployments.

ABOUT YOU

• Proven experience designing and delivering robust backend systems, with a strong focus on scalability, maintainability, and performance.
• Deep understanding of relational databases, including hands-on experience with PostgreSQL, and confidence in writing optimised SQL.
• Practical experience with AWS services, such as Lambda, API Gateway, ECS, and S3, and an appreciation of serverless and event-driven architectures.
• Familiarity with DevOps practices, including CI/CD pipelines, containerisation, and infrastructure-as-code.
• Strong problem-solving skills and a structured, delivery-oriented mindset.
• Comfortable working cross-functionally in fast-paced Agile environments, with clear communication and a collaborative approach.
• Passionate about clean code, continuous learning, and building systems that are resilient and easy to operate at scale.

NICE TO HAVE

• Experience working in a FinTech or start-up environment.
• Exposure to observability tools
• Familiarity with security and authentication patterns (OAuth, SAML, etc.).
