Sr. Electrical Engineer

Full-time · On site, San Francisco

Summary of position

We are building the optical layer that the next generation of AI and quantum infrastructure will run on. Our hardware depends on fast, precise electronics to drive and control photonic devices. As Senior Electrical Engineer, you will own both the analog drivers and the embedded control of our hardware, from a route request to a verified optical state. You will design the driver electronics, FPGA and firmware, and the interface to our spatial light modulator. This is a hands-on role at an early-stage company, so you'll own real decisions and help set the technical bar as we grow.

What you'll do

  • Driver electronics. Design precision analog and mixed-signal drivers, including high-voltage outputs, for our photonic devices.
  • Board design. Design and prototype circuit boards (rigid and flex). Create production files and see boards through fabrication and bring-up.
  • Device interface. Own the electrical interface to the modulator backplane, working with vendors where needed.
  • FPGA and firmware. Develop deterministic control: pattern generation, state memory, timing, synchronization and readback.
  • Fault handling. Design for invalid inputs, missed deadlines, reset and power loss. Keep protective behavior deterministic.
  • Validation. Measure electrical performance and its optical consequences against system requirements.
  • Documentation. Release schematics, firmware and bench procedures that others can rebuild.
  • Cross-team work. Work with optics, device physics, test and network systems on specs and integration.

What we are looking for

  • MSc or higher in electrical engineering, physics or a related field.
  • At least 7 years of hands-on electronics design, including high-speed and mixed-signal work.
  • Recent prototype electronics you personally designed, brought up and debugged.
  • FPGA development (Verilog or VHDL) and embedded firmware.
  • Proficiency with PCB design tools (Altium, KiCad or similar).
  • Knowledge of signal integrity and PCB manufacturing constraints (multi-layer, flex, HDI).
  • Clear written and verbal communication, fluent English.
  • Comfortable using AI tools across the workflow.

Nice to have

  • Driving optoelectronic or photonic components.
  • High-voltage, many-channel driver design.
  • Display or spatial light modulator backplanes.
  • Real-time control with calibration lookup tables.

Compensation

  • Competitive salary commensurate with experience.
  • Equity and benefits available, to be agreed upon.
