Embedded Firmware Engineer — USB-C PD & ARM Bring-Up

Hikinex; Bellevue (WA); On-site; USD 110,000 - 160,000; Full time

Job summary

Hikinex is seeking an embedded firmware engineer to bring up new hardware built around USB-C Power Delivery controllers. You will develop firmware for 32-bit ARM MCUs, configure ICs over I2C/SPI/UART, and work hands-on at the bench with the hardware team to move from PCB to production-ready software.

You will debug firmware on ARM Cortex-M MCUs, work from datasheets, and document configurations while collaborating to isolate hardware vs. firmware issues.

Qualifications

• Strong embedded C on 32-bit MCUs, with interrupt and peripheral handling.
• Experience with USB-C/USB-PD negotiation and role management.
• Proficient in I2C/SPI/UART for peripheral control and debugging.
• Hands-on hardware bring-up from power-on to functioning firmware.
• Ability to read datasheets/schematics and configure parts accordingly.
• Proficient in bench debugging tools: oscilloscope, logic analyzers, SWD/JTAG.

Responsibilities

• Bring up new PCBs and validate power/clocks, enabling firmware on hardware.
• Develop and debug embedded C firmware for ARM Cortex-M MCUs.
• Configure companion ICs via I2C/SPI/UART.
• Implement and debug USB-C/USB-PD behavior including negotiation and fault handling.
• Debug at bench with tools and document decisions.
• Collaborate with hardware engineers to isolate issues.
