Overview:
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.
