About the role

You will support and build new functionality for an existing production system while collaborating with business analysts to translate requirements into technical solutions. Additionally, you will be responsible for refactoring code, improving system performance, and mentoring other developers within the team.

What they look for

Java Java 8 Java 17 Java EE JPA Hibernate Karaf Maven Git Jenkins SQL Apache Derby ReactJS Bootstrap CSS3 HTML5

Requirements

Candidates must have 8-10 years of software development experience, with at least 5 years in a senior role, and a tertiary qualification in Engineering or Computer Science. Strong proficiency in Java, Java EE, and related technologies like JPA, Hibernate, and SQL is required.

Full description

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.

What you will do:

  • 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.

  • Refactor

and improve the code so the product stays maintainable when the next requirement lands.

  • Evaluate

and improve performance and high-availability behaviour, not only feature delivery.

  • Write unit

and integrated system tests that show the change works as intended.

  • 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.

Requirements

What you need:

  • 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.

  • Strong

Java. Java 8 and above is required. Java 17 is preferred.

  • Java EE

server-side development, JPA/Hibernate, and an application server or container. Karaf is preferred.

  • Maven, Git

and Jenkins. SQL and a relational database. Apache Derby is relevant.

  • ReactJS,

Bootstrap, CSS3 and HTML5, plus REST or SOAP.

  • A working

knowledge of the SDLC as it applies to a software team, not only as a diagram.

  • You

deliver production-quality software: attention to detail, your own unit tests, and support through the quality testing phase.
