Field application engineer

Efficient Computer is rethinking computing from the ground up to solve one of AI's biggest challenges: energy. Our Fabric architecture delivers a 10–100x improvement in energy efficiency for general-purpose computation, including AI, while supporting familiar programming languages and software frameworks—unlocking new possibilities for autonomous machines, intelligent infrastructure, wearables, and space systems. With our first processor, Electron E1, now shipping in volume and more than $97 million in Series B financing recently announced, we're accelerating customer deployments and scaling our architecture to data center performance. Join us to build the hardware and software that bring intelligence wherever it's needed and help shape the next generation of computing.

We are seeking a Field Application Engineer to join our growing Sales Support team. Efficient's Field Application Engineers are the technical bridge between our customers and our engineering team, guiding customers from first evaluation through design-in and production. This position is a unique opportunity to shape how a new processor architecture is adopted in the market as part of a highly interdisciplinary team, helping to demonstrate the value of Efficient's breakthrough technology. You'll work directly with customers and help write the playbook: building reference designs, demos and application notes, and feeding what you hear from customers straight back to our Product and Engineering teams.

If you have experience as a Field Application Engineer who wants to be part of an intensely skilled team and wants to have an immediate impact on the growth of our Sales organization, we want to talk with you!
