French is a plus. NICE TO HAVE * Deep understanding of DFM and DFA principles to ensure scalable production. * Proficiency in PCB library management and component lifecycle tracking. * Experience with control electronics for optical or laser-based systems is a significant plus. RESPONSIBILITIES * Develop complex PCBs with a primary focus on high-speed digital interfaces and sophisticated power distribution networks. * Lead the validation of hardware prototypes, utilizing structured testing and systematic fault analysis to support our fast-paced iteration cycles. * Collaborate with our optical and software teams to optimize circuit performance and resolve cross-domain design challenges. * Conduct and participate in rigorous design reviews to ensure first-pass success for all PCB iterations. * Assist in the design and implementation of control and measurement electronics for custom lab setups and hardware characterization. * Execute electrical circuit simulations using SPICE and IBIS models to predict and verify hardware behavior. * Contribute to PCB layout , ensuring signal integrity and thermal performance are maintained throughout the routing process. 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.
