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
Efficient’s Embedded Engineers design and implement firmware, applications and hardware that feature the world’s most energy-efficient programmable processors. The role’s primary responsibility is developing firmware and applications for our processors. The role’s responsibilities also include enhancing and maintaining our bare-metal SDK, porting RTOSes to run on our processors, developing hardware (development kits and bring-up boards) and participating in pre-silicon and post-silicon engineering activities (validation and verification).
This position is a unique opportunity to develop cutting-edge hardware and software as part of a highly interdisciplinary team, helping to demonstrate the value of Efficient’s breakthrough technology. If you are an engineer who wants to be part of an intensely skilled team and wants to have an immediate impact building the next generation of energy-efficient embedded applications, this is for you!
- Develop and deploy firmware and applications for our processors, in software simulation, RTL emulation, and on silicon
- Enhance and maintain our low level SDK and set of standard libraries
- Perform silicon validation and verification activities
- Develop bring-up test hardware and customer EVKs
- Perform board bring-up
- Perform first-silicon bring-up and checkout activities
- Engage with Digital Design and Compiler teams to debug silicon issues

What We Do
Efficient is building the world’s most energy-efficient general-purpose processor by combining ultra-efficient hardware with an intuitive, developer-friendly compiler and software stack that unlocks 10–100× efficiency gains across every part of an application, including AI. Efficient was founded in 2022 to commercialize a breakthrough in efficient computation developed over nearly a decade by a team of world-leading computer architects. Efficient's world-class team has produced two silicon implementations of the Fabric architecture: the Electron E0, a prototype system-on-chip, and the Electron E1, the first silicon product. With Efficient's cutting-edge effcc Compiler and software stack, the Electron E1 processor has been delivered to customers as of mid-2025, ramping to large-scale volume and distribution in 2026. Efficient already has customer traction in areas such as physical AI for infrastructure and automation, space and defense, automotive, and consumer products. Efficient's technology scales from tiny “beyond the edge” devices to large-scale robotics, autonomy, edge cloud, and datacenter applications—enabling widespread adoption across multiple industries and positioning Efficient as the solution to the energy problem across all of computing.
