Who We Are
Silicon Labs (NASDAQ: SLAB) is a global leader in secure, intelligent wireless technology for a more connected world. Our integrated hardware and software platform, intuitive development tools, and robust ecosystem simplify the path to market for customers building smart home, industrial, and commercial IoT products.

The Role
We’re looking for a Senior Engineer to join our SoC Platform Software team. You’ll play a critical role in bringing up new SoCs, developing and maintaining low-level drivers and firmware, and delivering production-quality software functionality across a wide range of embedded platforms.
This role will focus on implementing peripheral drivers, optimizing real-time OS integration, and enabling robust, low-power, high-performance device features used by thousands of developers and millions of devices worldwide.

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.
  • 7+ 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.

Benefits & Perks: 

Not only will you be joining a highly skilled and tight-knit team where every engineer makes a significant impact on the product; we also strive for good work/life balance and to make our environment welcoming and fun.
