Electronic System Engineer - Senior

Job Title

Electronic System Engineer - Senior

Role Summary

Design and validate high-speed electro-optical links and their electrical integration into complex systems. Work with photonics and product teams to translate component specifications into system-level electrical requirements and ensure manufacturable, testable designs.

Role based at the Palaiseau site, contributing to development of laser driver circuits, photodiode readouts, RF architecture and system verification for AI-focused optical interposers.

Experience Level

Senior level. Target experience: approximately 5–10 years of relevant industrial experience in electronic system design, preferably in optical communications or high-speed interconnects.

Responsibilities

Primary responsibilities include system architecture, design, validation and cross-functional integration.

• Define RF system architectures for high-speed optical links and optimize signal integrity and overall performance.
• Specify electrical interfaces between optical components (lasers, detectors) and electronic subsystems.
• Develop system-level specifications that map component performance to integrated link requirements.
• Design and optimize laser driver circuits and photodiode readout electronics, including transimpedance amplifiers.
• Plan and execute system-level characterization and performance verification versus specifications.
• Develop and validate models for architecture-level simulations; analyze test data to identify bottlenecks and propose design improvements.
• Collaborate with photonics, product and manufacturing teams to ensure technical feasibility and support integration during product development.

Requirements

Must-have technical skills and experience for immediate contribution.

• 5–10 years industrial experience in electronic system design for high-speed links or related fields.
• Deep understanding of RF/high-frequency circuit design, signal integrity and EMC.
• Proficiency in analog and mixed-signal design: amplifiers, filters, high-speed interfaces.
• Hands-on experience designing laser driver circuits and transimpedance amplifiers for photodetectors.
• Experience with system integration and defining/validating electrical subsystem interfaces.
• Familiarity with high-speed test equipment: oscilloscopes, network analyzers and optical instrumentation.
• Strong problem-solving, attention to detail, independent working ability and effective cross-team communication.
• Professional proficiency in English. French is a plus.
• Nice-to-have: Python programming skills.

Education Requirements

Engineer degree, Masters degree or PhD in Electrical Engineering, Electronics or a related technical field; a PhD is valued but not mandatory if compensated by significant industrial R&D experience. Equivalent practical/industrial experience will be considered.
