What you'll do

Play a critical role in ensuring the functional integrity, performance, and reliability of next-generation optical chips.

Required Skills and Experience

• Bachelor's, Master's, or PhD in Electrical Engineering, Computer Engineering, or a related field.

• Proven fluency and hands-on expertise in SystemVerilog for verification.

• Demonstrated prior experience with the UVM framework and modern verification environments.

• Direct knowledge of PCIe protocols and experience verifying digital logic for high-speed interfaces.

• Practical experience verifying RISC-V CPU designs or equivalent digital processor architectures within an ASIC context.

• Strong analytical and communication skills for customer-driven projects and interdisciplinary teamwork.

• Language: English at a proficient level. French is a plus.

Responsibilities

• Develop robust verification plans for complex digital and mixed-signal optical chip designs.

• Collaborate closely with architects, designers, and customers to understand logic requirements, translate them into verification strategies, and deliver clear, actionable feedback throughout the development process.

• Perform netlist-level simulations with SDF back-annotation for timing-accurate verification

• Support FPGA/ASIC bring-up and post-silicon validation as needed

• Develop, maintain, and optimize testbenches and verification components using advanced SystemVerilog features, such as constrained random testing, assertions, and transaction-level modeling, to create robust coverage-driven environments.

• Design scalable, reusable UVM-based environments and components (e.g., agents, monitors, scoreboards) for block- and system-level verification. Employ UVM to achieve regression automation, functional coverage closure, and high bug-detection efficiency.

• Develop and execute verification strategies for digital blocks implementing or interfacing with PCI Express (PCIe). Apply protocol-checking, compliance validation, error injection, and debug skills for PCIe endpoints and root complex devices. Use protocol analyzers and simulation environments to validate correct implementation across all protocol layers.

• Participate in the verification of RISC-V CPU cores and subsystems. Create test plans targeting processor modules (ALU, decoder, register file, control logic), with reference model comparisons, signature checks, and coverage of edge-case scenarios. Leverage formal verification and compliance suites for thorough design validation.

• Plan and perform end-to-end ASIC verification, from block-level testbenches to full-chip integration. Execute functional and regression tests, formal verification, and coverage analysis. Debug and resolve design issues, ensuring pre-silicon reliability before manufacturing. Engage in design reviews and system-level protocol validation with cross-functional teams.

Desired attributes

• Proactive in anticipating and mitigating design risks, including the assessment of undetected flaws via coverage-driven and formal verification.

• Proven ability to deliver in fast-paced, collaborative startup environments.

• Ownership mindset, attention to detail, and commitment to high product quality.

Pay and benefits

• Competitive cash compensation, with final package based on location, experience, and the pay of team members in similar positions.

• Meaningful stock option plan offered at the earliest stage of the company (included in the majority of full time offers).

• Relocation bonus and coverage of moving expenses for relocation within 20 minutes of the company's location.

• Healthcare coverage (including family-friendly options), pension contributions, professional development support, and 25 days of PTO, in addition to public holidays.

• Ownership of a key technical domain, with significant vertical and/or horizontal growth opportunities, based on performance and individual drive.

• Reimbursement of 50% of the public transport subscription fee.

• A high-paced, multicultural (with 10 nationalities), and engineering-led environment.
