Embedded Firmware Engineer (USB-C PD Bring-up)

Title: Embedded Firmware Engineer (USB-C PD Bring-up)

Headcount: 1

Location: Bellevue, Washington - Hybrid (3 days onsite)

Contract: 6 months w/ possibility of conversion; Start: Immediate start

Interview Process: 30-minute screener call, 1-hour technical interview, 1-hour conceptual and behavioral collaboration assessment; Feedback SLA: Weekly

Why Hiring:

- Hardware design standardized on USB Type-C creating too much firmware work for the current team of two.

- Compounded by the hiring manager's upcoming paternity leave.

End Product:

- Firmware for hardware built around USB-C Power Delivery controllers across three different SOCs, shipping production-quality embedded firmware.

Tech/Domain Environment:

- Embedded C, bare-metal firmware

- ARM Cortex-M microcontrollers

- USB-C Power Delivery controllers, Cypress / Infineon MCUs

- I2C, SPI, UART low-speed intra-IC buses

- Multimeter, logic analyzer, oscilloscope

Job Duties:

- Bring up new hardware systems and PCBs by validating power, clocks, and connecting debuggers

- Develop bare-metal embedded C firmware for USB-C Power Delivery controllers on ARM Cortex-M MCUs

- Configure and interface with low-speed intra-IC buses like I2C and SPI for peripheral companion ICs

- Implement and debug USB-C and USB-PD power negotiation, source, sink, and DRP roles

- Debug live hardware and firmware at the bench using multimeters, logic analyzers, and oscilloscopes

- Collaborate closely with hardware EE engineers to isolate and resolve hardware and firmware issues

Must Haves:

- Strong embedded C development experience on 32-bit microcontrollers

- Working understanding of USB-C and USB-PD source, sink, and DRP roles and power contract negotiation

- Experience with I2C, SPI, and UART peripheral communication and debugging

- Hands-on hardware bring-up and debugging experience using oscilloscopes, logic analyzers, and multimeters

- Schematic and datasheet literacy for register configuration and pin/power confirmation

Nice to Haves:

- Specific experience with Cypress or Infineon MCU SDKs and middleware such as ModusToolbox

- Prior work with Infineon EZ-PD or Cypress CCGx PD controllers

- Firmware update or bootloader work using DFU

Disqualifiers:

- Unable to work hybrid with 3 days onsite in Bellevue

- Not a US Person

Security/Clearance:

- US Persons Required
