We are looking for several experienced and highly driven Senior Analog Mixed-Signal Design Engineer to join our silicon development team.

In this role, you will design high-performance analog and mixed-signal integrated circuits for state-of-the-art high-speed data converter products. You will drive the development of novel circuit topologies, execute detailed transistor-level implementations, and lead silicon validation activities, while mentoring junior engineers. This is a key technical leadership position requiring deep analog expertise, strong hands-on design capability, and exceptional cross-functional collaboration skills to ensure first-pass silicon success.

 

YOUR MISSION

  • Lead transistor-level design of high-performance analog and mixed-signal blocks including ADCs, DACs, PLLs, LDOs, bandgaps, amplifiers, comparators, clocking circuits, and complete data converter subsystems.
  • Partner with system engineers and architects to translate system-level requirements into detailed circuit specifications and robust design implementations.
  • Drive, in close collaboration with the analog design and layout team, the specifications of the IC analog sub-blocks to get the best area/power/performance trade-off
  • Perform comprehensive transistor-level simulations and verification.
  • Drive top-level integration of analog and mixed-signal subsystems.
  • Collaborate closely with layout engineers to ensure optimal floorplanning, symmetry, matching, shielding, and parasitic-aware design techniques.
  • Support silicon bring-up, lab validation, characterization, and root-cause debugging.
  • Analyze silicon measurement results, ensure correlation with simulations.
  • Contribute to and lead technical design reviews, risk assessments, and comprehensive documentation.
  • Collaborate cross-functionally with digital design, verification, product engineering, and test teams.
  • Provide strong technical leadership, mentor junior engineers, and continuously improve design methodologies.
  • Write documentation in accordance with company Quality Assurance policy

 

YOUR PROFILE

  • Proven track record of architecting, designing, and bringing to production multiple complex analog/mixed-signal ICs in advanced CMOS technologies
  • Deep expertise in high-speed, low-noise, and high-linearity analog circuit design
  • Strong technical leadership with a clear ownership mindset and accountability for deliverables
  • Excellent analytical, problem-solving, and debugging skills
  • Ability to mentor junior engineers and elevate overall team technical capability
  • Strong communication skills with the ability to work effectively in cross-functional and multicultural teams (English required).

 

SKILLS & EXPERIENCE

  • Master’s or PhD degree in Electrical Engineering or a related field, with a strong focus on analog/mixed-signal IC design.
  • 10+ years of hands-on experience in analog/mixed-signal IC design in deep submicron CMOS technologies.
  • Strong foundation in analog fundamentals including device physics, noise analysis, linearity, stability, mismatch, yield, and reliability.
  • Extensive experience with transistor-level circuit design and simulation tools within the Cadence design suite (e.g., Virtuoso, Spectre), including corner and statistical verification methodologies.
  • Proven experience designing high-performance blocks such as data converters, clocking circuits (PLLs/DLLs), high-speed interfaces, or precision analog front-ends.
  • Deep understanding of layout-dependent effects, matching strategies, parasitic extraction flows, and analog layout best practices.
  • Hands-on experience with silicon lab validation, characterization setups, and systematic debugging methodologies.
  • Familiarity with ESD, latch-up, reliability qualification, and production test considerations.
  • Demonstrated ability to take full ownership of complex design blocks from concept definition through silicon validation and production release

 

PRACTICAL INFORMATION

  • Contract type: Permanent (CDI)
  • Location: Jacou / Sèvres / Meylan / Caen
  • 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.
