Senior Java Developer

Job Description - Senior Java Developer

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.
