ABOUT THE ROLE

NanoXplore is a pioneering French fabless company designing FPGA and e-FPGA solutions for the most demanding environments, including aeronautics and defense. With offices in Sèvres, Grenoble, and Montpellier, we are constantly looking to strengthen our teams.

To support the growth of its ASIC/SoC design activities, NanoXplore is hiring a Physical Implementation Engineer. Reporting to the team lead within a multidisciplinary team recognised for its expertise, you will work on advanced technology nodes (28 nm, 7 nm, and beyond).

 

YOUR MISSION

Physical Implementation (RTL to GDSII)

  • Own all or part of the physical implementation flow: floorplan, clock tree synthesis (CTS), and place & route (P&R).
  • Perform post-layout verification: STA, power analysis, IR Drop, equivalence checking, DRC, and LVS.
  • Work closely with front-end (design) and analog teams to ensure design flow consistency throughout the project.

 

Flow Development & Project Support

  • Contribute to resolving project-specific challenges, in liaison with the project manager, customer, or suppliers.
  • Proactively propose improvements to design methods and flows.
  • Progressively take ownership of a full chip and improve the physical implementation flow to address new constraints (foundry requirements, technology nodes, EDA tools).

 

PERSONAL QUALITIES

Autonomy and rigour in conducting physical implementation activities.

  • Methodology and commitment to quality, with adherence to ISO-9001 procedures.
  • Strong communication skills to work effectively in a cross-functional (digital, layout, measurements) and multicultural environment.
  • Ability to work within a multidisciplinary team on highly technical projects.
  • Good command of written and spoken English.
  • Intellectual curiosity and genuine interest in advanced ASIC/FPGA technology nodes.

 

SKILLS & EXPERIENCE

Education

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

Experience

  • First experience in place & route and/or post-layout verification (STA, DRC, LVS).
  • Experience on advanced technology nodes (28 nm and below) is a valued asset.

Technical Skills

  • Proficiency in Cadence back-end design tools: Innovus, Genus, Tempus.
  • Proficiency in Synopsys tools: PrimeTime, StarRC.
  • Proficiency in Mentor/Siemens tools: Calibre (DRC/LVS).
  • Solid understanding of the full RTL to GDSII design flow.

 

PRACTICAL INFORMATION

  • Contract type: Permanent (CDI) — Full time
  • Location: Meylan
  • 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.
