Flux is looking for a Director of Systems: Electronics to lead the design, integration, and execution of the electronic subsystems that power our Optical Tensor Processing Unit (OTPU).
At Flux, the unit of progress is the build—a tightly-scoped, cross-disciplinary prototype that integrates updated optical, electronic, and mechanical elements into a working system.
Reporting to the VP of Engineering, you will be the single point of accountability for all electronic subsystems outside the ASIC: high-speed analog front-ends, FPGA logic and firmware, power delivery, control systems, and system-level integration. Your focus is on execution—driving the roadmap, coordinating across disciplines, and ensuring each prototype advances Flux’s long-term architecture toward manufacturable, high-performance compute hardware.
This is a managerial and integrative leadership role, operating in close partnership with the VP of Optical Systems. While your optics counterpart leads light-based subsystems (sources, modulators, detectors, packaging), you own the electronic domain—ensuring the analog and digital front-ends, timing, control, and system integration meet performance, reliability, and manufacturability goals.
You’ll work closely with the Electronics Architect, who defines the detailed technical direction, while you lead execution, resourcing, and roadmap delivery. Supplier management and volume manufacturing are handled separately by our Operations & Manufacturing teams.
Success in this role demands deep technical breadth, strong people leadership, and relentless execution focus.
ResponsibilitiesPrototype 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.
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.
ASIC design and tape-out – owned by the Director of Hardware-ASIC.
Optical subsystem development – owned by the VP of Optical Systems.
Supplier execution, volume procurement, and factory logistics – handled by the Director of Operations & Manufacturing.
