Silicon Laboratories Wireless IC Design Engineer Jobs
Silicon Labs builds the EFR32 wireless SoCs that sit inside door locks, thermostats, and industrial sensors that have to run for years on a single coin cell. That constraint shapes every design role here. Wireless IC engineers co-optimize the RF front end, baseband, and power management so a radio can wake, transmit, and drop back to sleep on a current budget measured in microamps.
The open roles cover RF transceiver design, baseband IC development, ultra-low-power analog, and mixed-signal SoC integration. Day to day, that means RF CMOS circuit design, low-power analog techniques, and enough protocol-layer knowledge to design against IEEE 802.15.4, Bluetooth 5.x, and Z-Wave requirements. The EFR32 Series 2 parts carry Bluetooth LE, Zigbee, Thread and Matter, Z-Wave, and proprietary sub-GHz stacks, often running concurrently, so designers who understand the stack above the silicon are in demand.
Silicon Labs runs wireless design teams out of its Austin, TX headquarters and its Boston, MA office, plus international sites in Oslo, Norway and Tampere, Finland. The Oslo and Tampere teams trace back to the EnergyMicro and Zentri acquisitions and carry deep low-power and connectivity experience. You can sort companies hiring for semiconductor design by location and seniority to match those sites.
The company narrowed its focus in 2021 when it sold its infrastructure and automotive IC business to Skyworks Solutions. What is left is a company built entirely around IoT wireless connectivity, which means the engineering culture points at one hard problem: pushing wireless power efficiency further every generation. For an RF or mixed-signal designer, that focus is a feature. You work with people who care about the same nanoamps you do.
If you have shipped a low-power radio or tuned a receiver chain for sensitivity at sub-milliwatt budgets, these roles will feel familiar. Adjacent RF IC design engineer jobs on the board show how the same skill set travels to phones and base stations.

FAQ
What wireless standards do Silicon Labs IC design engineers work with?
Silicon Labs engineers design for Bluetooth LE, Bluetooth Mesh, Zigbee, Thread, Z-Wave, Wi-Fi 6, and proprietary sub-GHz protocols including Wi-SUN and MIOTY. The EFR32 multi-protocol SoC supports concurrent operation of several standards on one chip.
What makes IoT IC design at Silicon Labs technically challenging?
The chips have to hit very low active and sleep currents to support years of battery life. That requires co-optimizing the RF front end, baseband, and power management circuits at the transistor level inside a single CMOS SoC.
Does Silicon Labs have wireless IC design engineers outside the US?
Yes. Silicon Labs runs wireless IC design teams in Oslo, Norway and Tampere, Finland, which bring expertise from the Zentri and EnergyMicro acquisitions. SemiDesignJobs lists global Silicon Labs openings alongside the US roles.
