Their next vision was to develop an IoT sticker, a computing element that can power itself by harvesting radio frequency energy, bringing connectivity and intelligence to everyday products and packaging, things previously disconnect from the IoT. This revolutionary mixture of cloud and semiconductor technology is being used by some of the world's largest consumer, retail, food and pharmaceutical companies to change the way we make, distribute, sell, use and recycle products. Our investors include Softbank, Amazon, Alibaba, Verizon, NTT DoCoMo, Qualcomm and PepsiCo. We're looking for software engineers to join our growing team and help build the next generation of data-driven applications that bring intelligence to individual cases across the supply chain. These applications will unlock insights at the granular level—tracking location, temperature, humidity, product freshness, and more help global enterprises act on them in real time. This is a hands-on engineering role focused on designing, building, and deploying applications that interface with Wiliot's IoT cloud, device data, and enterprise systems. You'll work closely with product managers, hardware teams, and customer-facing leads to deliver high-impact software at scale.
