We make it easy for developers to solve complex wireless challenges throughout the product lifecycle and get to market quickly with innovative solutions that transform industries, grow economies and improve lives.

Why this position matters

The Internet of Things is a fast growing, innovative market.  Silicon Labs has invested in several exciting and market-leading highly integrated mixed signal SoCs aimed at IoT. The low power Gecko MCUs and Wireless MCUs that we develop will be deployed in literally millions of products worldwide. The IoT is the future of Silicon Labs and the SoC Implementation team plays an important role in the realization of that future. As a Middle-End Design Engineer, you will work with our design team to define and deliver key flow’s and chip implementations within the low power wireless MCU platform.

Is this a great match for you?

It is if you are a highly motivated, self-driven, talented Engineer with demonstrated knowledge of the IC design flow, all the way from initial idea to implementation. Engineers inquiring about this position should be familiar with digital implementation tools with focus on middle-end implementation like, synthesis, logical-equivalence checks, low-power intent. Basic knowledge of place and route to support physical-aware synthesis is desired. Successful candidates will have excellent written and oral communication skills in English and will be comfortable explaining technical concepts to a wide range of audiences, including senior engineering leaders.

The candidate will be a technical contributor as part of a digital design team implementing highly integrated mixed signal SoC’s for IoT products, include MCU and Wireless SoCs, performing middle-end implementation using deep sub micron technology.
