NanoXplore is a pioneering French fabless company designing FPGA, SoC-FPGA, and ASIC solutions for the Space, Aeronautics & Defense markets. With offices in Paris, Grenoble, and Montpellier, we are constantly looking to strengthen our teams.

NanoXplore is looking for a Test Engineer to develop and execute production and characterisation test solutions for its FPGA components. The role is primarily based at the CNES laboratory in Toulouse, with occasional travel to the Paris headquarters and Grenoble site. You will work in close collaboration with NanoXplore design engineers.

 

 

KEY RESPONSIBILITIES

Production Test Development (ATPG)

  • Develop the hardware and software production test solution (ATPG) for NanoXplore FPGAs, in close collaboration with NX design engineers.
  • Create and validate ATPG test patterns (STIL format) for production use on ATE platforms.
  • Debug and qualify test programs on ATE platforms (e.g. mu-Test, Advantest V93K or equivalent).

 

Laboratory Characterisation & Debug

  • Conduct laboratory studies on NanoXplore components: digital, analog, and software characterisation, and FPGA debug on board.
  • Perform measurements and characterisation of power consumption, timing, I/O voltage levels, and RF parameters.
  • Diagnose and resolve hardware issues at board level using appropriate lab instruments and debug techniques.

 

Collaboration & Reporting

    • Work in close collaboration with NX design, validation, and software engineers to align test strategy and results.
    • Document test methodologies, results, and characterisation data; write clear technical reports.
    • Liaise with CNES and other institutional partners on-site in Toulouse as required.

 

PERSONAL QUALITIES

Strong technical curiosity and hands-on problem-solving mindset.

 

  • Rigour and precision in measurement, characterisation, and test documentation.
  • Autonomy and initiative in managing test activities end-to-end.
  • Good communication skills for cross-team collaboration in a multidisciplinary environment.
  • Team spirit and adaptability, comfortable working in an institutional lab setting (CNES, Toulouse).
  • Good level of English for reading technical documentation and interacting with international partners.

 

SKILLS & EXPERIENCE

Education

  • Master's degree or equivalent in Electronics, Microelectronics, or a related field.

Experience

  • Experience in test engineering for electronic components (FPGA, ASIC, or similar).
  • Prior experience with ATPG flows and production test on ATE equipment is a strong plus.

Technical Skills

  • FPGA programming knowledge: VHDL and/or Verilog.
  • Scripting skills: Python, C++, VBA or equivalent.
  • Laboratory experience: hands-on use of measurement equipment and characterisation techniques (power consumption, timing, I/O voltage levels, RF) and board-level debug.
  • Knowledge of ATPG concepts, ATE debug (e.g. mu-Test, V93K), and STIL pattern creation is a plus.
  • Proficiency in versioning tools: Git and/or SVN.
  • Interest in the space, aeronautics, or defense sectors is appreciated.

 

PRACTICAL INFORMATION

Permanent contract (CDI) — Full time. Primarily based at CNES laboratory, Toulouse. Occasional travel to Paris and Grenoble. Salary according to profile.

 

  • Contract type: Permanent (CDI)
  • Location: Toulouse (CNES) — with occasional travel to Paris and Grenoble
  • Package: salary according to profile + internal benefits
  • Start date: as soon as possible

Embedded Systems

Bridging the gap between silicon and software, the Embedded Systems team designs the low-level tools that make NanoXplore’s FPGAs truly usable and powerful. 


Their core mission : developing the main SDK (Software Development Kit), firmware, and all embedded components that enable seamless configuration, control, and integration of our devices. From bootloaders and drivers to board support packages and diagnostic tools, they ensure our chips speak the right language whether on a satellite, in a defense system, or in a test environment. Their work is foundational : without it, nothing runs. 


What sets them apart is their ability to think system-wide. They work closely with hardware teams and application engineers, adapt to evolving specs, and support real-world use cases with reliability and reactivity. 

They’re not just writing code : they’re building the ecosystem around our FPGAs.


Driven by curiosity and precision, it’s a team where autonomy meets collaboration, and where each line of code contributes to something bigger : making advanced microelectronics accessible and operational for the most demanding applications.
