Principal Electrical Engineer

About Us:

Voyant Photonics is redefining how machines see the world.

Our LiDAR-on-chip products enable compact, affordable, and power-efficient 3D sensing for robotics, drones, industrial automation, and beyond.

By replacing bulky, mechanical LiDARs with solid-state solutions built on integrated photonics, we’re delivering high-performance sensing at scale. With Voyant, machines can sense, understand, and navigate their environments with unprecedented precision.

Why Join Us:

As a growing company, we’re looking for engineers who want to move fast, solve hard problems, and leave their mark on a foundational technology. You’ll join a mission-driven team at the intersection of product design, silicon photonics and machine perception.

Location: San Francisco, Hybrid

Key Responsibilities:

• Architect 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.

Qualifications:

• Experience: 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 Qualifications:

• Experience 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).

Benefits Package:

• Competitive base salary and a meaningful equity package.

• Comprehensive health benefits (Medical, Dental, Vision).

• Unlimited PTO and paid company holidays.

• Team events and company meetups.
