RESPONSIBILITIES * Design and simulate analog and RF integrated circuits, including critical blocks such as amplifiers, mixers, PLLs, ADCs, DACs, and bias/reference circuits, with a focus on signal integrity, linearity, and precision. * Optimize circuits for power, area, and performance trade-offs, ensuring designs meet system-level requirements across process, voltage, and temperature (PVT) variations. * Collaborate closely with optics, simulation and PCB teams to define architecture and block-level specifications for Arago’s successive prototypes and product iterations, ensuring tight alignment with overall performance and integration goals. * Work with layout engineers to guide floor-planning and physical design, minimizing parasitic effects and preserving analog precision in layout-sensitive blocks. * Support post-silicon validation and bring-up, defining test plans, analyzing lab measurements, and correlating results with simulation to refine future design iterations. * Language: English at a proficient level. French is a plus. REQUIRED SKILLS AND EXPERIENCE * A sound mathematical understanding and deep physical intuition of analog electronics, as well as analog voltage-to-current and current-to-voltage conversion at low and high frequencies. * Experience in designing high-precision analog systems for signal processing or power electronics. Experience working with high-frequency analog signals is valued. * Extensive experience in IC design and post-layout design methodology using standard industry tools like Cadence Virtuoso. * Proficiency in designing and optimizing mixed-signal circuits, including DACs and ADCs at low (kHz-MHz) and high (>GHz) frequencies, and signal conditioning circuits, ensuring flawless integration between analog RF components and digital processors. * Strong understanding of signal integrity, crosstalk, and noise reduction techniques in mixed-signal environments, particularly in high-frequency RF systems interfacing with digital processors. * Advanced node experience required (<28nm). 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 9 nationalities), and engineering-led environment.
