Principal Electrical Engineer

OverviewJoin to apply for the Principal Electrical Engineer role at Voyant Photonics.Location: San Francisco, HybridAbout Voyant PhotonicsVoyant Photonics is transforming machine perception with a new class of LiDAR devices that are compact enough to fit in the palm of your hand and powerful enough to measure range, velocity, and reflectivity with unparalleled accuracy. By leveraging cutting-edge silicon photonic chips, we deliver sensors that are not only revolutionary in performance but also affordable enough to integrate into any system. Our technology disrupts bulky, expensive, and power-hungry LiDAR systems, enabling high-precision sensing for robotics, autonomous vehicles, drones, industrial automation, and beyond.Key ResponsibilitiesArchitect and develop analog and mixed-signal electronics for compact, high-performance hardware modules, using TIAs, ADCs, precision current sources, and power supplies like LDOs and switching regulators.Own designs from concept through production, including schematic capture, component selection, and PCB layout in collaboration with layout engineers.Ensure signal integrity, power integrity, and EMI/EMC compliance across high-speed and noise-sensitive interfaces.Define and execute bring-up, characterization, and validation plans (e.g., DVT, EVT), with a focus on robustness, repeatability, and manufacturability.Analyze design trade-offs (performance, cost, power, integration complexity) in the context of tightly constrained product architectures.Partner closely with system architects, mechanical engineers, and firmware teams to ensure seamless integration and system-level reliability.QualificationsExperience: 7+ years in hands-on hardware development, with end-to-end ownership of systems that shipped at scale.Execution: Demonstrated ability to deliver high-reliability designs under tight constraints on power, cost, form factor, and schedule.Technical Strengths:Deep expertise in low-noise analog and high-speed digital design.Strong grounding in signal/power integrity, high-density interconnect, and EMI mitigation techniques.Familiarity with high-volume design-for-manufacturing (DFM), reliability testing, and yield optimization.Tools & Skills:Proficient in schematic capture and simulation (e.g., SPICE), with working knowledge of Altium or similar.Experience with SI/PI simulation tools (e.g., HyperLynx, SiWave) and measurement tools (GHz-range scopes, VNAs, spectrum analyzers).Familiarity with board-level integration of FPGAs, microcontrollers, and custom analog ASICs.Preferred QualificationsExperience with high-speed ADCs, custom analog IC interfaces, or photonics-related electronics.Knowledge of flex and rigid-flex PCB design.Familiarity with Verilog-AMS or mixed-signal modeling.Exposure to Verilog HDL or FPGA development.Experience designing for high-reliability or harsh environments (e.g., automotive, aerospace).BenefitsCompetitive base salary and a meaningful equity prehensive health benefits (Medical, Dental, Vision).Unlimited PTO and paid company holidays.Team events and company meetups.Equal Opportunity EmployerVoyant Photonics is an equal opportunity employer committed to building a diverse and inclusive workplace.
