Test Systems Software Engineer - #187845

Expleo is a trusted partner for end-to-end, integrated engineering, quality services and management consulting for digital transformation.  We help businesses harness unrelenting technological change to successfully deliver innovations that will help them gain a competitive advantage and improve the everyday lives of people around the globe.

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
  
  

Qualifications

• 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.
