Office Coordinator

About Atomic Semi

Atomic Semi is building a small, fast semiconductor fab.

It’s already possible to build this with today’s technology and a few simplifications. We’ll build the tools ourselves so we can quickly iterate and improve.

We’re building a small team of exceptional, hands-on engineers to make this happen. Mechanical, electrical, hardware, computer, and process. We’ll own the stack from atoms to architecture. Our team is optimistic about the future and we want to continue pushing the limits of technology.

Smaller is better. Faster is better. Building it ourselves is better.

We believe our team and lab can build anything. We’ve set up 3D printers, a wide array of microscopes, e-beam writers, general fabrication equipment - and whatever is missing, we’ll just invent along the way.

Atomic was founded by Sam Zeloof and Jim Keller. Sam is best known for making chips in his garage, and Jim has been a leader in the semiconductor industry for the past 40 years.

About the role:

We’re looking for an Office Coordinator who can keep our office running smoothly and make sure the little things never get in the way of the big things. You’ll be the go-to person for day-to-day operations: stocking supplies, managing resource calendars, handling maintenance requests, and making sure our spaces are ready for the team to do their best work.

As Office Coordinator, you’ll be the first face people meet at Atomic Semi. Your welcoming, professional, and warm presence will set the tone for the entire team. If you’re proactive, detail-driven, and thrive on keeping the office running like clockwork while solving problems on the fly and keeping things seamless, this role is for you.

• Keep office operations moving: manage the front desk, own calendars, support visitors and coordinate vendor requests.

• Ensure the office is stocked: including grocery orders, Monday breakfasts, weekly lunch coordination, and supply restocking. You'll oversee our dayporter and janitorial staff, setting cleaning schedules and resolving issues quickly.

• Set up and maintain the office environment — managing furniture, desks, AV equipment, and security systems.. When we open or refresh a space, you're the one making it happen.

• Mailing and logistics: handling Amazon returns, scheduling Uber couriers, and related tasks.

• Plan and execute company events end-to-end, owning logistics, vendors, and follow-through.

• Be the face of the office — greeting guests and candidates, ensuring every visit feels seamless from room setup to catering to last-minute logistics.

What makes you a great fit:

• Detail-oriented with a knack for staying organized.

• Proactive and resourceful—you spot what needs doing and make it happen.

• Comfortable juggling multiple tasks without losing track.

Required experience

• Event support experience (team off-sites, exec meetings, small gatherings).

• Vendor management or negotiation experience.

• Strong written communication skills for clear, professional correspondence.

• Experience as an office coordinator, office manager, or similar role

• Hands-on experience setting up and managing office infrastructure — AV, hardware, security systems, and contractor coordination

• Comfortable managing facilities vendors

Nice to have

• Passion for nanotechnology or interest in deep tech.

• Experience working at a startup or fast-scaling company.

• Familiarity with tools like Slack, Google Workspace, and Notion.

• Eye for workspace design and making environments feel welcoming.
