Software Engineer

Akkodis is seeking a Software Engineer for a Contract job with a client in Bellevue, WA . Ideally looking for applicants with a solid background in the Embedded C development on ARM Cortex-M microcontrollers., Bring up new PCBs: validate power/clocks, connect a debugger, enable peripherals, and get firmware running on new hardware

• Develop and debug embedded C firmware on ARM Cortex-M-class MCUs
• Configure and drive companion ICs over I2C or other peripheral buses
• Implement and debug USB-C / USB-PD behavior (power negotiation, source/sink roles, fault handling, etc.)
• Debug at the bench with oscilloscope, protocol/logic analyzer, multimeter, and SWD/JTAG
• Work from datasheets, register tables, and schematics
• Document configurations and design decisions
• Collaborate with hardware engineers to isolate hardware vs. firmware issues

• Embedded C development on ARM Cortex-M microcontrollers.
• USB-C / USB Power Delivery (USB-PD) experience.
• Hardware bring-up and debugging of new PCBs.
• I2C, SPI, and UART communication protocol expertise.
• Oscilloscope, logic analyzer, SWD/JTAG, and embedded hardware debugging experience.

Preferred Skills:

• Infineon/Cypress MCU development (Modu Toolbox, EZ-PD, PMG1, CCGx).
• Bootloaders and firmware update mechanisms (DFU).
• Power electronics or power-path control firmware (VBUS, OVP, UVP, OCP).
• USB subsystem experience (USB hubs, DisplayPort Alt Mode, retimers, billboard devices).
• CI/CD pipelines for embedded firmware builds.
• USB-IF compliance and certification testing., Strong embedded C on 32-bit MCUs (ARM Cortex-M or similar): interrupts, register-level peripheral work, development under flash/RAM constraints
• Working understanding of USB-C/USB-PD (source/sink/DRP roles, power contract negotiation)
• 2C/SPI/UART peripheral/companion-IC communication, configuration, and debug
• Hands-on hardware bring-up experience: taking a board from power-on to running firmware, or debugging firmware against real hardware
• Datasheet and schematic literacy: able to configure a part from its register tables and confirm pin/power connections
• Comfortable with standard bench debug tools: oscilloscope, logic/protocol analyzer, SWD/JTAG debugger, UART logging
• Git proficiency

Rate Range: $110/hour to $116/hour; The rate may be negotiable based on experience, education, geographic location, and other factors
