Engineer I - Software Design

What You ll Do

• Develop, maintain, and optimize peripheral drivers (GPIO, UART, I2C/I3C, SPI, DMA, timers, ADC, CAN, SDIO, etc.) in C for multiple SoC families.
• Lead development and integration of the USB Device stack, including:
• Control path (EP0), composite/class support (CDC, HID, MSC, DFU, Audio).
• Transfer management, suspend/resume, LPM/remote wakeup.
• Protocol compliance and power-aware operation (HS/FS).
• Integrate and maintain RTOS (e.g., FreeRTOS, Zephyr) for real-time, resource-constrained systems:
• Task scheduling, ISR design, memory protection (MPU), tickless idle, and synchronization.
• Support new silicon bring-up: boot sequences, clocking, memory map setup, cache/MPU configuration, and debug interfaces (JTAG/SWD).
• Contribute to the Gecko SDK: ensuring consistency, quality, and integration with tools like Simplicity Studio.
• Collaborate with hardware, validation, security, apps, and product teams on feature development, bring-up, and support.
• Write technical documentation, integration guides, and internal specifications.

What You ll Bring

• BS/MS in Electrical Engineering, Computer Engineering, or related field.
• 2+ years of embedded firmware development experience on ARM Cortex-M/A or RISC-V SoCs.
• Strong proficiency in C and embedded systems debugging (JTAG, trace analyzers, oscilloscopes).
• Hands-on experience building and shipping USB Device solutions using vendor or open IP cores (e.g., Synopsys DWC2/3, Cadence, Mentor).
• Familiarity with USB device class stacks (CDC-ACM, HID, MSC, Audio, DFU).
• Proven knowledge of RTOS internals and real-time scheduling.
• Peripheral driver development with DMA and concurrency awareness.

Preferred Qualifications :

• Experience with USB-IF compliance, protocol analyzers (Total Phase, LeCroy, Beagle), or custom descriptors.
• Familiarity with low-power system design: tickless idle, wake-up sources, retention/sleep modes.
• Secure firmware development (secure boot, signed updates, debug lockdown) is a plus.
• Prior experience with Silicon Labs Gecko SDK and Simplicity Studio toolchain is a strong plus.
