Job Title: Embedded Firmware Engineer (USB-C, PD)

Job Description

We are seeking an embedded firmware engineer to join our team in developing cutting-edge hardware centered around USB-C Power Delivery controllers. You will play a crucial role in transforming bare PCBs into production-quality firmware. This position involves writing and debugging firmware on 32-bit ARM microcontrollers, configuring companion ICs over I2C/SPI/UART, and collaborating closely with our hardware team.

Responsibilities

• Bring up new PCBs by validating power and clocks, connecting debuggers, enabling peripherals, and running firmware on new hardware.
• Develop and debug embedded C firmware on ARM Cortex-M-class microcontrollers.
• Configure and drive companion ICs over I2C or other peripheral buses.
• Implement and debug USB-C / USB-PD behavior, including power negotiation, source/sink roles, and fault handling.
• Perform debugging at the bench using tools such as oscilloscopes, protocol/logic analyzers, multimeters, and SWD/JTAG.
• Work from datasheets, register tables, and schematics to document configurations and design decisions.
• Collaborate with hardware engineers to isolate hardware versus firmware issues.

Essential Skills

• Proficiency in embedded C on 32-bit microcontrollers (ARM Cortex-M or similar), including interrupts, register-level peripheral work, and development under flash/RAM constraints.
• Understanding of USB-C/USB-PD, including source/sink/DRP roles and power contract negotiation.
• Experience with I2C/SPI/UART peripheral/companion-IC communication, configuration, and debugging.
• Hands-on experience with hardware bring-up, from power-on to running firmware or debugging firmware against real hardware.
• Ability to read and interpret datasheets and schematics to configure parts from register tables and confirm pin/power connections.
• Competence in using standard bench debugging tools such as oscilloscopes, logic/protocol analyzers, SWD/JTAG debuggers, and UART logging.
• Proficiency with Git for version control.

Additional Skills & Qualifications

• Experience with Cypress/Infineon MCU SDK/IDE and its middleware, such as ModusToolbox or STM32Cube, including creating/customizing board support packages.
• Experience with firmware update/bootloader work, such as DFU or equivalent, including building and flashing update images.
• Knowledge of power-path or regulator firmware, including VBUS control, fault detection/recovery, and enable/soft-start sequencing.
• Experience with USB subsystems, including hubs, DisplayPort Alt Mode, redrivers/retimers, or billboard devices.
• Familiarity with USB-IF PD compliance/USB-C requirements.

Work Environment

This position offers a flexible 3-day work schedule in an office environment. You will have the opportunity to be part of an early-stage team in Bellevue, contributing to the development of some of the world's most advanced technology.
