Executive Assistant

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.

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:

• Own complex calendar management across two cofounders, balancing evolving professional and personal priorities

• Coordinate travel, expenses, appointments, errands, and day-to-day logistics with exceptional attention to detail

• 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

• 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

• 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

We are in the business of building trust. We take our values seriously and treat them as commitments to each other, held to the same bar as the ones we make to customers.

• Strong back: high standards, keep our promises, work hard.

• Fast feet: experiment, cut scope, take delight in pace.

• Eyes up: wrestle with the mission, and let where AI is heading shape our strategy, our teams and our day-to-day work.

• Open heart: say the scary thing, create connection, make room for emotions.
