Job Description

Efficient is developing the world’s most energy-efficient general-purpose computer processor. Efficient’s patented technology uses 100x less energy than state of the art commercially available ultra-low-power processors and is programmable using standard high-level programming languages and AI/ML frameworks. This level of efficiency makes perpetual, pervasive intelligence possible: run AI/ML continuously on a AA battery for 5-10 years. Our platform’s unprecedented level of efficiency enables IoT devices to intelligently capture and curate first-party data to drive the next major computing revolution.

If you are a Computer Architect who wants to impact the transformation of the next evolution of computing, we would like to talk to you. Efficient is hiring an Computer Architect with experience in design-space exploration across the hardware-software interface. We seek individuals who are comfortable designing and executing experiments and interpreting and visualizing data.

This is a unique opportunity to get in at the ground level and have influence on our products as we move from initial stages of product development to market release and scaled volume production. Join our team and help us shape the future of computing at the edge and beyond!
