- Engineer scalable, fault-tolerant systems with clustered caching (Infinispan) and JGroups.
- Contribute to deployment automation (Liquibase, Ansible) and CI/CD pipelines.
- Write automated acceptance and regression tests within a BDD framework; partner closely with QA.
- Participate in estimation, planning, code/design reviews, and production readiness.
- Strong SQL and database design.
- Infinispan (or equivalent clustered cache) and understanding of JGroups.
- JAX-RS/REST, API design, HTTP fundamentals, and secure web-app principles (PCI awareness).
- Concurrency/multithreading and performance troubleshooting.
- Tooling: Maven, CI/CD (Jenkins/GitLab/GitHub Actions), Liquibase, Ansible.
- Practice with BDD/TDD; comfortable authoring automated tests.
- SE II: ~3-6 years' experience. Senior: 8+ years with leadership/ownership stories.
Nice to Have:
- BigQuery, WebSockets, Pub/Sub (Kafka/RabbitMQ/SNS/SQS).
- Docker/Kubernetes; GCP/AWS; Observability (metrics/logs/tracing).
Why Join:
- Impact at scale: Core gateway that powers real-world payments across the globe.
- Modernised J2EE: Stable architecture + contemporary engineering (IaC, automation, hybrid cloud).
- End-to-end ownership: Small teams, big outcomes, minimal bureaucracy.
