Full Job Description
About the role

We're looking for a Senior Electrical Engineer to help architect, design, and ship next-generation neurotech hardware products. As a key member of our growing hardware team, you will own major portions of the electrical system from early architecture through production and play a critical role in bringing complex consumer electronics to life.
What you'll do
  • Electrical System Architecture & Product Development
    • Lead electrical architecture and board-level design for mixed-signal consumer hardware systems from concept through production.
    • Own schematic design and guide development through EVT, DVT, PVT, and mass production.
    • Define system partitioning, interfaces, and component selection across compute, sensors, connectivity, and power subsystems.
    • Drive rigorous design reviews and help establish strong electrical design and manufacturing standards.
    • Collaborate closely with mechanical, firmware, and software teams to optimize performance, size, thermal behavior, and reliability.
    • Operate effectively in a startup environment where engineers own large portions of the hardware stack.
  • High-Speed & High-Density Hardware Design
    • Design high-density, multi-layer PCBAs using HDI techniques, fine-pitch BGAs, and controlled-impedance routing.
    • Implement high-speed digital interfaces such as USB, Quad-SPI, MIPI, CSI/DSI, DDR, or similar buses.
    • Design analog and mixed-signal circuits including amplifiers, filters, sensor interfaces, and ADC/DAC connections.
    • Optimize PCB layout for signal integrity, power integrity, and low-noise performance.
  • Power Electronics & Battery Systems
    • Define system-level power architecture for battery-powered consumer and wearable devices.
    • Design and integrate high-efficiency DC-DC converters (buck, boost, and related architectures).
    • Optimize power consumption, battery runtime, and quiescent current across active and standby modes.
    • Design and integrate battery charging and power management solutions for Li-ion/Li-poly systems.
    • Consider thermal constraints and power density in compact or sealed wearable devices.
  • Validation, Bring-Up & Debug
    • Lead board bring-up and electrical debugging across analog, digital, and power domains.
    • Use advanced lab instrumentation including oscilloscopes, logic analyzers, spectrum analyzers, and high-speed probes.
    • Define and execute validation plans including signal integrity, power integrity, and environmental testing.
    • Perform root-cause analysis and resolve hardware issues discovered during development or production.
  • Manufacturing & Production (DFM / DFT)
    • Design hardware with strong Design for Manufacturing (DFM) and Design for Test (DFT) principles.
    • Support EVT, DVT, and PVT builds and ramp hardware to mass production.
    • Work with contract manufacturers and suppliers to resolve manufacturing and yield issues.
    • Develop or support manufacturing test infrastructure, including programming, calibration, and test fixtures.
Requirements
  • 5+ years of experience in electrical or hardware engineering.
  • Experience shipping at least one consumer electronics product, preferably compact or wearable devices..
  • Strong experience designing high-density, multi-layer PCBs with controlled impedance and fine-pitch components.
  • Solid understanding of analog and mixed-signal circuit design.
  • Experience implementing system power architecture for battery-powered products.
  • Experience designing or integrating DC-DC converters and power management circuits.
  • Experience with high-speed interfaces such as USB, Quad-SPI, MIPI, DDR, or similar.
  • Strong hands-on experience with board bring-up, debugging, and lab validation.
  • Understanding of signal integrity and power integrity in high-density electronic systems.
  • Experience working cross-functionally in fast-paced product development environments.
Strong candidates may have
  • Experience designing wearable or body-worn devices with tight power, size, and thermal constraints.
  • Strong experience with Altium Designer or equivalent PCB tools.
  • Experience supporting EVT, DVT, and PVT builds and ramping hardware to mass production.
  • Experience designing manufacturing test fixtures or automated test systems.
  • Familiarity with thermal analysis for compact electronics.
  • Experience with embedded firmware development (C/C++).
  • Experience with Python for lab automation or instrumentation control.
  • Familiarity with EMI/EMC pre-compliance testing and mitigation.
  • Deeper power electronics experience including converter loss analysis and control loop analysis and compensation design


Compensation Range

$150,000 - $200,000/year
Benefits
  • Competitive equity package
  • Comprehensive medical, dental, and vision insurance
  • Company size: 20-30 people
  • Unlimited PTO
  • Visa sponsorship
  • 3% 401k matching
