Senior Java Developer Opportunity in Pretoria or Somerset West

Seeking an experienced Senior Java Developer to support and enhance a live production product. The role involves collaborating with business analysts and developers, building new functionality, improving performance and high availability, debugging integrated systems, deploying applications, and providing mentorship. Candidates should have 8 to 10 years of software development experience, including at least five years as a senior developer, and strong Java EE, JPA/Hibernate, ReactJS, REST, or SOAP skills.

This is a senior Java seat on a live product, not a greenfield build. The system is already in production. New work has to fit what is there, and a change that looks fine in isolation can break something three modules away.

You will know the domain, work with the analysts, and ship changes that do not take the product down. Two roles are open, in Pretoria or Somerset West. You will sit in a development team, not as a lone contractor. Mentoring is part of the job, both ways: you follow the standards that already work, and you help other developers when their change does not.

Support the existing product and build new functionality and components on top of it. Work with business analysts to understand the domain and turn new requirements into something that can actually be built. Evaluate and improve performance and high-availability behaviour, not only feature delivery. Do root-cause analysis on bugs in an integrated system, including debugging other people’s code and fixing test data when that is what is broken.

Build and deploy on an application server, then incorporate other developers’ work and get the system running again after the merge. A relevant tertiary qualification in Engineering or Computer Science, or matric plus the experience below. 8–10 years in a software development environment, of which at least 5 years as a senior developer in a team. Java EE server-side development, JPA/Hibernate, and an application server or container. Karaf is preferred.

ReactJS, Bootstrap, CSS3 and HTML5, plus REST or SOAP. You deliver production-quality software: attention to detail, your own unit tests, and support through the quality testing phase.
