• Prepare and maintain technical artefacts such as source-code documentation, test records, configuration files, software release notes, and installation instructions.


• Participate in code reviews and incorporate feedback from the Senior Software Engineer and project team.


• Use Git and approved configuration-management processes to manage source code, branches, baselines, and software releases.


• Support build, deployment, and test-environment set-up activities, including Linux-based development and integration environments.


• Assist with customer demonstrations, factory acceptance testing, site integration, commissioning, and troubleshooting when required.


• Participate in technical discussions with system engineers and other disciplines to understand interface requirements, expected data flows, and integration constraints.


• Maintain awareness of software quality, cybersecurity, and configuration-control requirements relevant to the project.

Requirements

• Degree or diploma in Computer Science, Computer Engineering, Electrical/Electronic Engineering, or a related discipline.


• Up to 3 years of relevant software-development experience; strong fresh graduates with suitable project experience may be considered.


• Good foundation in C++ programming, including object-oriented design, memory management, debugging, and standard data structures.

• Familiarity with Git or another source-control system.


• Familiarity with Linux or willingness to develop competence in a Linux-based software-development environment.


• Ability to read technical specifications, follow structured development tasks, and document work clearly.


• Strong analytical, problem-solving, and troubleshooting skills.


• Good teamwork and communication skills.
