Alljoined is creating a future where humans are fully understood and augmented by technology. Our work solves the communication bottleneck between humans and computers by decoding thoughts from the brain, entirely non-invasively. We apply deep learning research to large-scale EEG datasets to decode multimedia input, eventually moving to internal thought. We are state-of-the-art in our capabilities and fully vertically integrated. Our goal is to develop a general consumer interface that completely transforms how we live our lives.
We are actively growing our world-class team of researchers and operators to build the next interface to improve individual lives and the well-being of society as a whole.
About the RoleAs an Executive Assistant & Office Manager, you will support our CEO and help keep the company operating smoothly as we grow. You will own calendar and inbox workflows, coordinate meetings and travel, prepare briefings, protect focus time, and ensure important follow-ups do not fall through the cracks. You will also manage day-to-day office logistics, team events, onboarding and offboarding, recruiting coordination, and our upcoming office move.
This is a unique opportunity to work closely with a technical founder at an early-stage deep-tech company and gain a front-row seat to how a frontier AI and neurotechnology company is built. You will collaborate with the operations lead and the broader team to anticipate needs, reduce friction, and develop lightweight systems that make the company more effective. This is an in-office role based in San Francisco, five days per week.
