- Collaborate across engineering teams to ensure deliverables are technically accurate, testable, and on time.
- Lead technical discussions around architecture, tooling, and process improvements.
- Support deployments to internal test environments and production data centres.
- Mentor and guide team members, promoting best practices in software delivery.
Essential Experience
- 8+ years’ experience in backend engineering, ideally within a Fintech or high-availability environment.
- Expert-level Java / J2EE development, including design patterns, OO design, and refactoring.
- Proven experience delivering secure, scalable, high-quality services in production.
- Hands-on with JPA2, Hibernate, and MySQL 8 (InnoDB).

- Experience building fault-tolerant, multi-threaded systems and working with load balancing concepts.
- Familiarity with CI/CD, automation, and Behavioural Driven Development (BDD).
- Comfortable deploying applications on cloud infrastructure (AWS, GCP, or Azure).
- Excellent communication, analytical, and problem-solving skills.
Desirable Skills
- Experience with Infinispan, JGroups, or clustered caching solutions.
- Exposure to NoSQL databases (e.g. BigQuery).
