About the role

CUBECOM designs, develops and manufactures RF communication systems for satellite applications, including antennas, transmitters and ground support equipment. As it enters a scale-up phase, it is hiring a Software Developer in Stellenbosch to own the proprietary production test systems that verify every unit before it goes into orbit. The role involves developing Python test scripts, C# PC applications and databases that drive the test stations, working closely with product developers.

Key responsibilities

• Design, develop and maintain production test software, including Python test scripts and C# applications that control test equipment and automate test sequences.
• Translate Acceptance Test Specifications (ATS) into production tests with product developers, keeping requirements traceable.
• Work with engineers on test equipment and fixtures controlled by PC-based applications, including RF test instrumentation.
• Design and maintain databases (e.g. MySQL) for the large volumes of test data, ensuring integrity, traceability and performance.
• Link tests to the product configuration database so each unit is verified against its correct baseline.
• Automate the generation of Acceptance Test Reports (ATRs) from recorded results.
• Develop clear operator interfaces for test stations and integrate the test systems with production, quality assurance and engineering.
• Apply version control, code reviews, documentation and change control, and provide support for test failures and data queries.
