Senior Engineer – SoC Platform Software (USB Device, Peripherals, RTOS)

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.
