Executive Assistant

About AIUC

AIUC builds standards and insurance for frontier AI. Our mission is to Underwrite superintelligence . We exist because risk, not capability, is becoming the binding constraint on AI being useful. History offers lessons for how to build confidence in new technology; electricity burned down houses until insurers funded Underwriters Laboratories (UL) to certify products against their standards. Today, the UL mark is a trustmark on every light bulb in America. We’re building that for AI.

AIUC-1, our standard for agent security, serves frontier builders like Cursor, Lovable, ElevenLabs, and Harvey. We've raised $55m from Ribbit, First Harmonic and Nat Friedman to audit frontier AI. Our team comes from METR, Anthropic, McKinsey, and OpenAI. Come join us.

The Role

We're hiring an Executive Assistant to partner closely with AIUC's cofounders. This is a high-trust role for someone who anticipates needs, solves problems quickly, and ensures nothing falls through the cracks.

You'll support the founders across both professional and personal priorities, owning everything from complex scheduling and travel to special projects, events, and day-to-day logistics. In return, you'll gain a front-row seat to building one of the world's most ambitious AI companies and learn firsthand how a category-defining startup is built.

This role is ideal for someone who is exceptionally organized, dependable, and excited by the opportunity to work alongside experienced founders.

In this role, you will:

Manage executive inboxes, draft and triage communications, and ensure important follow-ups never slip through the cracks

Organize founder dinners, company events, and other high-impact moments with end-to-end ownership

Anticipate needs before they arise, creating leverage for the founders by proactively solving problems and removing operational friction

Improve how the founders operate by streamlining workflows, automating repetitive tasks, and leveraging AI tools where appropriate

Assist with other operational endeavors, as arise in a high-growth start-up environment

What we're looking for

3–7 years of experience supporting senior leaders or operating in high-performance environments, ideally in consulting, legal, VC/PE, technology, or similar fields

Exceptional organizational skills with meticulous attention to detail and a reputation for flawless execution

Strong written and verbal communication skills with the judgment to represent the founders professionally

High ownership and reliability; you take initiative, move quickly, follow through, and can be trusted with sensitive information

Strong professional judgment and polish when interacting with executives, customers, investors, and partners

Comfortable switching between strategic priorities and highly tactical work; no task is beneath you

Comfortable using AI tools such as ChatGPT or Claude to improve speed and efficiency

Excited to work in person five days a week with flexibility beyond traditional office hours when needed

Nice to have

Previous experience supporting founders or C-level executives at a startup

Experience planning events, offsites, or executive travel

Interest in AI, startups, and emerging technology

Experience building systems and processes that improve operational efficiency
