## About the Role

+ - 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)
 + I2C/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
Preferred Skills

 + - Experience with a Cypress/Infineon MCU SDK/IDE and its middleware (e.g. ModusToolbox, STM32Cube, or similar), including creating/customizing a board support package
 + Firmware update/bootloader work (DFU or equivalent): building and flashing update images
 + Power-path or regulator firmware: VBUS control, fault detection/recovery (OVP/UVP/OCP), enable/soft-start sequencing
 + USB subsystem experience: hubs, DisplayPort Alt Mode, redrivers/retimers, or billboard devices
Nice to have

 + - Prior work with Infineon EZ-PD / PMG1 (or Cypress CCGx) PD controllers and ModusToolbox
 + CI for embedded builds
 + USB-IF PD compliance/USB-C requirements familiarity

## Description

Role Description
We're bringing up new hardware built around USB-C Power Delivery controllers and are looking for an embedded firmware engineer to help take these boards from bare PCB to working, production-quality firmware. You'll write and debug firmware on 32-bit ARM microcontrollers, configure companion ICs over I2C/SPI/UART, and work hands-on at the bench in collaboration with our hardware team., + - 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
