Job Description

Expleo is a global engineering, technology, and consulting partner helping businesses innovate, transform, and deliver high‑quality products and solutions. With expertise spanning aerospace, automotive, transportation, telecommunications, financial services, and life sciences, we support clients in solving complex engineering challenges while accelerating innovation. Our teams combine deep technical knowledge with a hands‑on mindset, working collaboratively to drive measurable impact and operational excellence.

 

We are currently looking for a HW/SW Integration Test Facility Software Engineer to support advanced space system programs.


About the role:
We are seeking a mid‑level Software Engineer with a strong background in firmware and testing to design and develop software that controls and performs black‑box testing of space payload components.
You will build and operate a Hardware/Software Integration Test Facility for an optical payload, working closely with hardware, firmware and test engineers. The role involves developing tools and utilities that interface with real, flight‑like hardware to validate functionality, performance, reliability, security and in‑orbit operability during payload integration

 

  • Design, develop and operate software for a HW/SW Integration Test Facility
  • Contribute to software requirements definition and high‑level architecture
  • Develop and maintain test‑facility software in Python and C
  • Implement telemetry/telecommand handling, monitoring and validation tools
  • Develop measurement and visualization tools for high‑speed data
  • Support firmware and FPGA image update validation
  • Integrate and test software with real hardware in a laboratory environment
  • Contribute to test automation and regression frameworks
  • Support debugging at application and system integration level (hardware‑in‑the‑loop)
  • Maintain technical, design and user documentation

 

 

  • Bachelor’s degree in Software Engineering, Computer Science, Electrical/Electronics Engineering or equivalent experience
  • 3–6 years of professional software development experience with exposure to firmware and system‑level testing
  • Strong proficiency in Python; experience with C required
  • Hands‑on experience with HW/SW integration and laboratory testing
  • Solid understanding of hardware interfaces and protocols (CAN, I2C, SPI, UART, Ethernet)
  • Strong debugging, analytical and problem‑solving skills
  • Experience with Linux/Windows environments and Git
  • Exposure to C++, CAN tooling, data visualization or high‑performance systems is a plus
