Job description
We are seeking a Test Systems Software Engineer to join a specialist Test Engineering Software group supporting the design, development and sustainment of engineering test equipment used to validate complex defence systems and sub-assemblies.
This role focuses on developing robust, maintainable software for test equipment and engineering test solutions across the full product lifecycle, from early concept and prototyping through to production and in-service support. You will work in a software engineering lab environment closely integrated with electronics, instrumentation and hardware teams, collaborating across multiple engineering disciplines to deliver high-quality, reliable test capability to meet programme delivery schedules.
This position suits a hands-on software engineer who enjoys working at the intersection of software, hardware and electronics rather than purely desktop or web-based development. Responsibilities:
- Design and develop software for automated and semi-automated engineering test systems
- Implement test solutions using C, C++, C# and appropriate scripting languages
- Develop software to interface with instrumentation, data acquisition devices and custom electronic hardware
- Integrate software with communications and control interfaces (Ethernet, serial, field buses, etc.)
- Support hardware bring-up, system integration, debugging and fault-finding activities in lab environments
- Create modular, maintainable and reusable test frameworks and architectures
- Apply software engineering best practices including unit testing, code reviews and continuous integration
- Contribute to automation, build pipelines and DevOps workflows
- Produce technical documentation, requirements traceability and test artefacts
- Collaborate with systems, electronics, firmware and production teams to define and deliver test capability
- Support issue resolution and ongoing improvement of deployed test systems, + Ensure our recruitment process is inclusive and accessible
- Communicating and promoting vacancies
- Offering an interview to disabled people who meet the minimum criteria for the job
- Anticipating and providing reasonable adjustments as required
- Supporting any existing employee who acquires a disability or long term health condition, enabling them to stay in work at least one activity that will make a difference for disabled people
Requirements
Do you have experience in Unit testing?, * Degree (or equivalent experience) in Software Engineering, Computer Science, Electronic Engineering or a related technical discipline.
Essential skills:
- Strong programming skills in C/C++ and/or C#
- Experience developing software for test, instrumentation or hardware-integrated systems
- Understanding of automated test principles and engineering test methodologies
- Experience with LabWindows/CVI, NI TestStand, or similar test frameworks
- Familiarity with serial and network communications (RS232/422/485, Ethernet, CAN, Modbus, 1553, etc.)
- Practical debugging and fault-finding skills in lab environments
- Knowledge of software quality practices (unit testing, clean design, version control, CI/CD)
- Ability to read schematics and work alongside electronics hardware
- Strong problem-solving and analytical capability
- Effective communication and cross-functional collaboration skills.
Desired skills:
- Electronics or embedded systems knowledge
- Experience with automated test equipment (ATE) architectures
- Hardware control and data acquisition integration (DAQ, PXI, GPIB, VISA, etc.)
- Scripting languages (Python, PowerShell or similar)
- Continuous integration/build tooling and DevOps practices
- Experience working within regulated or safety-critical industries (defence, aerospace, automotive, medical)
- Exposure to Agile/Scrum environments
Experience:
- Proven experience developing software for engineering or hardware-integrated systems
- Experience delivering test systems or manufacturing/production test solutions preferred
- Experience working across the full development lifecycle from concept through deployment and support
- Experience working within multi-disciplinary engineering teams.
