Requirements

10+ years building and shipping complex high-speed electronic systems, from prototype to production—ideally in compute, networking, or photonics-adjacent domains
Proven success managing managers across at least three of the following: analog/RF electronics, mixed-signal design, FPGA/RTL development, embedded software, and system integration
Deep technical fluency in GHz-class analog front-ends, precision timing and clocking, high-speed PCB design, and mixed-signal system validation
A track record of fast iteration on prototypes, balancing exploratory R&D with rigorous configuration control
Strong communication and systems thinking—able to translate circuit-level trade-offs into architectural and business implications

Responsibilities

Prototype build ownership: Own the electronic execution of each OTPU prototype build. Define scope and success criteria for all electronic subsystems; lead weekly reviews with ASIC, Optics, Analog, and Software peers and reports
Team leadership: Directly manage the electronics and FPGA teams. Set clear goals, hire and mentor managers, and build a culture of high-speed, high-quality iteration
System-level alignment: Ensure the electronic architecture integrates cleanly with optical, mechanical, and software systems. Help to key architectural decisions across PCB stack-ups, clock and timing architectures, power sequencing, and signal integrity
Design-for-manufacture: Establish early-phase DFM/DFT principles across PCB design, interconnects, and test coverage, ensuring compliance with qualifications such as CE RED, and FCC. Own critical design reviews (CDRs) and final sign-off for analog front-end schematics, FPGA top-level timing, firmware/RTL interfaces, and board bring-up procedures
Cross-functional integration: Synchronize roadmaps with the VP of Optical Systems, VP of ASICs, Director of Software, and VP of Engineering. Ensure firmware, HDL, and software test harnesses are frozen for each build gate and that system integration milestones are consistently met
