J2EE Software Engineers (Mid to Senior Developer roles available - 100% remote)
Salary: £50-80k + bonus
About the Company:
Our client is building the front-of-house payment gateway for a fast-growing, private, top-25 US payments company. The platform has a 19-year lineage with a clear architectural direction in J2EE, modernised with hybrid cloud (GCP + on-prem) for scale, security, and compliance (PCI-DSS). You'll join a distributed, long-tenured engineering team delivering high-throughput, highly available transaction systems used across the globe.
The Role:
As a J2EE Software Engineer, you'll design and develop server-side products and APIs on the payment gateway, owning your deliverables end-to-end: discovery, design, development, automated tests, release, and monitoring. You'll work in small, empowered teams using BDD/TDD and CI/CD, shipping resilient features for real merchants and real transactions.
Key Responsibilities:
- Design, implement, and maintain J2EE services and RESTful APIs (JAX-RS/RESTEasy).
- Build robust persistence layers with JPA2/Hibernate on MySQL 8 (InnoDB).
- 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 & monitoring.
- Collaborate across product, security, and ops to meet PCI-DSS and reliability goals.
Essential Criteria:
- Server-side product development with J2EE/Jakarta EE (not a Spring-only/microservices role).
- Get hands-on with JBoss/WildFly application servers in production.
- JPA2/Hibernate with MySQL 8 (InnoDB); 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.
- Distributed culture: Colleagues across IE, NI, UK, and EU; collaborative, low-ego environment.
