Job Description & How to Apply Below
What you'll do
  • 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.

  • What we're looking for
    • 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/System Verilog) 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.

    Useful experience
    • 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.
