Meet the Team

We are developing highly flexible wireless SoCs in a fast-paced environment. The IoT Validation team has a vital role in ensuring product performance, scalability, and time to market. We are looking for an experienced engineer focusing on RF and DSP design validation of wireless IPs for low-power, high performance System-on-Chip IoT products. You will be part of a specialized, highly skilled IP-SoC development team spanning multiple wireless communications technologies such as Bluetooth Low-Energy, 802.15.4 Zigbee-Thread, 802.11 Wi-Fi, Wi-SUN, and proprietary short-range wireless. You will be taking designs through the complete development lifecycle from initial concept to silicon bring-up and optimization before shipping products.

Responsibilities

• Contribute to initial development of Zigbee, BLE, Wi-SUN, ZWave, MBus, and proprietary PHY configurations for Silicon Labs RF SoCs
• Perform pre-silicon testing utilizing a combination of block or chip-level test benches and FPGA emulation
• Generating test requirements from specifications compliant with the standards and protocols
• Bring-up and validate new Silicon Labs IP on silicon, providing support and feedback to cross-functional teams
• Perform lab measurements including RX sensitivity, frequency/baudrate/deviation tolerance, blocking, TX output power, PA modulation characteristics, EVM and more
• Provide technical expertise, up to and including owning the investigation, for radio issues which may be escalations from Applications, PTE, Systems, Marketing, etc.
• Work with Systems and Design teams to review the PRD to ensure we design and build quality products that can be thoroughly characterized under the constraints of schedule.
• Provide guidance to the SW team on proper RF SW implementations for a scalable test infrastructure platform and tools for efficient workflows

Skills You Will Need

Minimum Qualifications:

• BSEE + 6 years of relevant experience or MSEE + 4 years of relevant experience
• Experience using Python or other high-level modeling language/tool for designing and evaluating communication systems and algorithms

• Basic DSP knowledge (up/down sampling, FIR filtering)
• Experience with RF signal chains including LNAs, mixers, PAs, A/D and D/A
• Experience with digital modulation formats (MSK/FSK, OQPSK, OOK/ASK, etc)
• Proficiency taking measurements with standard RF lab instruments (signal generator, spectrum analyzer, network analyzer, scope, DMM, SMU)
• Knowledge of common wireless communications standards and protocols such as Bluetooth low-energy, 802.15.4, 802.11 WiFi, proprietary sub-GHz
• Demonstrated ability to generate high output in a self-driven manner

The following qualifications will be considered a plus:

• Familiarity with basic operation of CMOS transistors, op-amps
• Experience in revision control and configuration management systems
