Principal Electrical Engineer (Design Lead)

Midjourney • San Francisco, CA

3d

About The Position

Act as the in-house electrical lead for Midjourney Medical: own the electrical architecture of the scanner and the technical direction for all board-level design. Own complex board design end-to-end: architecture, schematic capture, layout (high-speed digital, analog/mixed-signal, power), DFM/DFT, fabrication and assembly vendor management, bring-up, and revision control. Write firmware for embedded targets (MCU/SoC): drivers, real-time control loops, safety-relevant logic, bootloaders, and field update paths. Audit and update HDL (FPGA) code for high-throughput data acquisition, timing/synchronization, triggering, and pre-processing of ultrasound and sensor data streams. Define electrical interfaces and data contracts with software, recon/ML and mechanical teams: timing budgets, clocking/sync, signal integrity, connectors/harnessing, and failure modes. Establish electrical engineering rigor: design reviews, schematic/layout review checklists, bring-up procedures, test fixtures, and documentation suitable for a regulated medical device program (DHF, traceability, change control). Mentor and grow the electrical function; select and manage external design partners where leverage is high.

Requirements

• Deep experience designing complex boards from blank page to stable revision, including high-speed digital and analog/mixed-signal domains.
• Strong schematic and layout skills (Altium/KiCad or equivalent) with real signal integrity, power integrity, grounding, and EMI/EMC instincts.
• Solid embedded firmware background in C/C++ (and Python for tooling): peripherals, DMA, interrupts, real-time constraints, and debugging on hardware.
• Practical HDL experience (VHDL/Verilog/SystemVerilog) for data acquisition, timing, and streaming interfaces.
• Track record of owning bring-up and debug on real hardware: scopes, logic analyzers, and disciplined root-cause analysis.
• Technical leadership: clear trade-offs, strong written documentation, and the ability to set the electrical bar for a lean, fast-moving team.

Nice To Haves

• Ultrasound, imaging, instrumentation, or other high-channel-count data acquisition systems (ADC/AFE front ends, transducer interfacing, pulser/receiver design, low-noise analog).
• FPGA-to-host high-bandwidth data paths (10/25/100G Ethernet, serial transceivers) and deterministic multi-board synchronization.
• Power electronics and power distribution for complex electromechanical systems: rail architecture, sequencing, isolation, and thermal considerations.
• Safety-critical or medical device electronics: interlocks, isolation and leakage requirements, IEC 60601-adjacent design practice, and design controls.
• Manufacturing and serviceability thinking: DFM/DFT, ICT/functional test fixtures, calibration flows, yield and field-failure analysis.
• Building an electrical function from scratch: tooling, libraries, part standardization, ECO process, and vendor ecosystem.
• Familiarity with high-performance computing systems.
