Senior Embedded Software Engineer Wireless
Austin TX

Silicon Labs is looking for a Senior Embedded Software Engineer - Wireless - to join our Austin-based RAIL team.

In this role you will help develop foundational embedded software that enables customers to build reliable power-efficient wireless products on Silicon Labs devices. You will work on software that supports both proprietary and standards-based wireless systems contributing to technology used across a broad range of IoT applications.

This is a great opportunity for an experienced embedded engineer who enjoys working close to the hardware solving complex technical problems and owning software from concept through release. While experience in wireless systems is a plus we are also excited to hear from candidates with strong embedded systems fundamentals who want to grow deeper in wireless applications.

Meet the Team

The RAIL team develops the Radio Abstraction Interface Layer (RAIL) SDK a common radio software platform that helps customers build wireless applications without needing to master device-specific radio details. Our work enables everything from low-power battery-operated devices to more complex multi-protocol systems.

As part of this team you will collaborate closely with firmware silicon systems and test engineers to deliver high-quality embedded software that helps customers build innovative connected products.

Responsibilities

As a Senior Embedded Software Engineer on the RAIL team you will:

• Design develop and maintain embedded software for Silicon Labs low-power wireless MCUs and SDKs
• Own support for hardware features through the entire IC lifecycle (design pre-silicon verification post-silicon verification release and long-term support)
• Build and enhance low-level firmware components such as device drivers initialization and startup code timing-sensitive system software and radio control features
• Optimize software for performance reliability power efficiency and memory/CPU utilization in real-time embedded environments
• Debug complex issues across software firmware hardware and system boundaries using lab tools and debuggers
• Collaborate with hardware silicon systems and product teams to define requirements review designs and support bring-up of new devices
• Contribute to automated test validation and development tooling to improve product quality and engineering efficiency
• Participate in code reviews design reviews and technical discussions that raise engineering quality across the team
• Mentor and support other engineers through technical guidance collaboration and best practices

Skills You Will Need

Minimum Qualifications:

• BS or MS in Electrical Engineering Computer Engineering Computer Science or a related field or equivalent practical experience
• 5 years of professional experience in embedded software or firmware development
• Strong programming skills in Embedded C and/or C
• Experience developing software for microcontrollers inresource-constrainedreal-time environments including bare metal and/or RTOS-based systems
• Strong debugging skills at the hardware/software boundary with hands-on experience using tools such as debuggers JTAG/SWD oscilloscopes or logic analyzers
• Experience working on low-level embedded software such as device drivers interrupts peripheral interfaces timing-sensitive code or memory-constrained systems
• Experience taking features from design through implementation test and release
• Strong problem-solving communication and collaboration skills

The following qualifications will be considered as a plus:

• Experience with wireless or connectivity technologies such as Bluetooth LE Zigbee Thread Wi-Fi or proprietary radio systems
• Experience with communication stacks radio control software PHY/MAC-related functionality or other timing-critical embedded software
• Experience optimizing embedded systems for low power performance and reliability
• Experience with common embedded interfaces and peripherals such as SPI I2C UART DMA timers and interrupts
• Experience with Python or similar scripting languages for tooling automation testing or build workflows
• Experience with automated test CI validation frameworks or hardware-in-the-loop test environments
• Experience with silicon bring-up hardware validation or close collaboration with chip or board design teams
• Experience with multi-core microcontrollers concurrency synchronization or shared-resource challenges
• Familiarity with assembly on ARM RISC-V or similar MCU architectures
• Experience using AI-assisted development tools (such as GitHub Copilot Cursor ChatGPT or similar) to support prototyping test development debugging automation and documentation with strong engineering judgment and validation practices
• Experience with artificial intelligence (AI) powered tools and technologies used to enhance productivity analysis and decision-making
  

Why Join Silicon Labs

• Work on foundational wireless technology used across a wide range of products
• Solve interesting technical problems at the intersection of embedded software hardware and wireless systems
• Collaborate with experienced engineers across firmware silicon systems and test
• Make a direct impact on technology that helps customers bring connected products to market faster
• Continue growing your technical depth in embedded systems and wireless applications
