We manufacture equipment, software, and systems that help plan, deploy, certify, monitor, and optimize a wide range of networks—from mobile phones to data centers and beyond. Our solutions extend to high‑performance thin‑film optical coatings and engineered diffusers, servicing sectors such as automotive, defense, and consumer electronics. At VIAVI, our employees are passionate about supporting customer success and thrive on collaboration and innovation.

Based in Saint‑Étienne, VIAVI Solutions France is hiring a Senior Digital Electronics Design Engineer to join its R&D department. The role involves designing high‑performance electronic boards for fiber‑optic test and measurement instruments, covering hardware architecture, schematic design, PCB routing, prototype qualification, and production release.

Duties & Responsibilities

• Define the hardware architecture of electronic boards, considering system constraints such as power, thermal, signal integrity, EMC, and product specifications.
• Design and validate electronic schematics; manage PCB routing and oversee prototype manufacturing.
• Test, debug, and qualify prototypes; write test plans and qualification reports to support production release.
• Contribute to system integration in collaboration with embedded software, mechanical, and manufacturing teams, and participate in architecture reviews.
• Monitor component and solution availability; evaluate and qualify new technologies relevant to VIAVI products.
• Document all developments—bill of materials, calculation notes, definition files—in accordance with department quality processes.

Required Skills

• An engineering degree in electronics (classical academic background preferred: CPGE / engineering school).
• At least 5 years of hardware design experience in an industrial R&D environment.
• Strong command of high‑speed digital design, with a solid understanding of analog constraints (noise, dynamic range, linearity) in measurement instruments.
• Ability to work in a cross‑functional team (software, mechanical, manufacturing) and communicate effectively with international stakeholders.
• Fluency in English and French.
• Self‑driven, rigorous, and curious, with a strong appetite for cutting‑edge technologies and a genuine interest in solving complex problems.

Required Technologies

• Digital design around FPGAs, SoCs, or microprocessors and their ecosystems (DDR memories, DC‑DC power, clocks, high‑speed buses: PCIe, USB 3.x, Ethernet GbE).
• VHDL/Verilog development for programmable logic (Xilinx/Intel).
• Proficiency in Cadence or equivalent for schematic capture and PCB routing review.
• Knowledge of signal integrity and electromagnetic compatibility (EMC); simulation experience (HyperLynx, SIwave or similar) is a plus.
• C/C++ and Python for board bring‑up, testing, and measurement automation.
