Executive Assistant, CEO

Every audit answers one question: can I trust this? For 150 years, people have answered it by hand. Clark is changing that.

We build AI that doesn’t just assist auditors. It does the audit work itself. More than 35 CPA firms already use Clark to run audit fieldwork faster and at equal or better quality. Audit is where we start. Our mission is to build the trust infrastructure layer for the AI economy, and we’re only getting started.

We’re a small, hard-working team backed by top investors. We take ownership and judge ourselves by results. If you want to change how an entire profession works, you’ll fit in here.

We are hiring an EA to the CEO to become the CEO’s operational leverage across scheduling, communication, company rhythm, recruiting, investors, customers, and day-to-day execution.

This person will help the CEO move faster, stay focused, and operate with more clarity as Clark scales. You will own calendar management, meeting preparation, follow-through, internal coordination, travel, and special projects that keep the company moving.

This is a high-trust role for someone who is organized, discreet, proactive, and excited to work directly with the CEO of a fast-moving AI company.

Clark is entering a phase where the company is scaling across engineering, AI, product, sales, customer success, audit domain expertise, infrastructure, and marketing.

As the company grows, the CEO’s time becomes one of Clark’s most important resources. The EA to the CEO will protect that time, create operating leverage, and ensure important priorities do not fall through the cracks.
