We are looking for talented people to join our team. If you want to be at the intersection of physics and engineering, collaborate with world-class scientists, and have the freedom to work with cutting-edge open source technology such as embedded Rust, LLVM, and next-generation FPGA tools such as the nMigen language and Yosys - then consider a job at M-Labs.
Our office is located in the center of Hong Kong, a cosmopolitan city with world-class infrastructure, many cultural and social events, and <a href="https://www.discoverhongkong.com/eng/see-do/great-outdoors/hikes/index.jsp" rel="noopener noreferrer" target="_blank">beautiful natural scenery</a>. It has a separate system from mainland China, where, for example, communications are unrestricted, taxes are low, and customs tariffs virtually inexistent. Hong Kong is located next to Shenzhen, a city with <a href="https://www.wired.co.uk/video/shenzhen-full-documentary" rel="noopener noreferrer" target="_blank">a bustling tech scene</a>, and where many of the world's electronic gadgets are designed and manufactured.
For local applicants, now is your chance to work on top-notch science and technology projects with partners worldwide, including Oxford University and <a href="https://www.nist.gov/nist-and-nobel/dave-wineland" rel="noopener noreferrer" target="_blank">NIST</a> - in <a href="https://web.archive.org/web/20170114210545/https://www.nature.com/articles/s41570-016-0001" rel="noopener noreferrer" target="_blank">a field whose applications are responsible for 20% of GDP</a>.
