- 6+ years of experience in application development or systems analysis, with a track record of delivering large-scale, complex technology initiatives.
- Deep expertise in Core Java, including object‑oriented design principles, concurrent and multi‑threaded programming, JVM memory management, and performance tuning.
- Hands‑on experience re‑engineering monolithic applications into microservices architectures, and deploying containerised workloads using Docker and Kubernetes.
- Practical knowledge of distributed systems and data processing frameworks such as Apache Flink, alongside distributed caching technologies such as Redis, Oracle Coherence, or GridGain.
- Database experience spanning relational platforms (preferably Oracle) and NoSQL technologies (preferably MongoDB), with the ability to design for scale and reliability.
- Proven domain knowledge in Capital Markets, including Derivatives, Credit Risk, and Risk Management, with experience supporting risk‑sensitive, business‑critical platforms.
- Bachelor's or Master's degree in Computer Science, Engineering, or a related STEM discipline, or equivalent practical experience in a comparable role.
