About Alljoined

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 Role

As an Office Manager & Operations Assistant, you will take ownership of our day-to-day office and facility operations and help keep the company running smoothly across a range of administrative and operational needs.

Your primary responsibility will be making sure our San Francisco office and facilities are well-run, organized, stocked, and set up to support our team. This includes managing day-to-day workplace needs, coordinating with vendors, and proactively identifying and resolving issues as they arise. You will also work closely with our Operations Lead to take on related tasks and support other administrative and operational needs across the company, from helping with events, onboarding, purchases, and team logistics to tackling other ad hoc needs as they come up.

This is a hands-on role for someone who enjoys taking ownership, solving problems, and jumping in wherever needed. As you get up to speed and demonstrate the ability to manage the core office and facilities responsibilities, there will be opportunities to take on more across administrative and operational areas based on your interests, strengths, and capacity.

This is a unique opportunity to work closely with a technical founder and Operations Lead 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 broader team to anticipate needs, reduce friction, and develop lightweight systems that make the company more effective.

This is an in-office, part-time role based in San Francisco, starting at approximately 10 hours per week, with the potential to expand in hours and grow into a full-time position over time.
