Software Engineer I

Meet the Team

You’lljoin Silicon Labs’RAIL team, which develops the Radio Abstraction Interface Layer (RAIL)—the embedded software that enables developers to configure, control, andoptimizewireless radios across Silicon Labs’ IoT products. The team works closely with radio, firmware, SDK, validation, and applications engineering teams to deliver reliable, high-performance wireless capabilities for technologies such as Bluetooth Low Energy, proprietary wireless, and multiprotocol IoT solutions.

Responsibilities

• Develop andmaintainembedded software features for SiliconLabswireless radio platforms. 

• Design, implement, test, and debug firmware in C/C++ for resource-constrained microcontrollers. 

• Support radio-control capabilities, includingtransmit, receive, power management, timing, and diagnostic features. 

• Collaborate with hardware, radio design, SDK, validation, and applications teams to bring new wireless products and features to market. 

• Investigate software and hardware integration issues using debuggers, logic analyzers, and other lab tools. 

• Contribute to code reviews, technical documentation, automated testing, and continuous improvement of development processes.

Skills You Need

Minimum Qualifications

• Master’s degree in Electrical Engineering, Computer Engineering, ora relatedtechnical field. 

• Strong interest in embedded software, wireless communications, and low-level system development. 

• Academic or project experience in embedded software development using C or C++. 

• Understanding offundamental wireless communication concepts, including RF, modulation, packet-based communication, or digital signal processing. 

• Familiarity with microcontrollers, embedded peripherals, interrupts, memory-constrained systems, and real-time software concepts. 

• Strong problem-solving, analytical, and debugging skills. 

• Ability to use development and debugging tools such as JTAG/SWD debuggers, oscilloscopes, logic analyzers, or protocol analyzers. 

• Ability to work effectively in a collaborative engineering environment and communicate technical concepts clearly.

• Ability to learn complex technical systems, analyze issues, and turn requirements into well-tested software. 

• Clear communication and a collaborative approach to solving engineering challenges.

The following skills will be considered a plus:

• Internship, co-op, research, or project experience related to embedded firmware, wireless systems, or IoT devices.

• Experience with bare-metal embedded software development, including low-level programming without an RTOS.

• Exposure toBluetooth Low Energy, Zigbee, Thread, Wi-Fi, proprietary wireless protocols, or multiprotocol systems. 

• Experience with Python or other scripting languages for test automation, data analysis, or development tooling. 

• Knowledge of RTOS concepts, device drivers, bootloaders, power optimization, or embedded security. 

• Exposure to Git, CI/CD workflows, unit testing, and automated hardware-in-the-loop testing. 

• Participation in engineering competitions, technical organizations, research publications, or relevant student leadership activities.
