TL;DR: Early-stage, IC-heavy CoS role for a builder who wants to run the operating system of the company.

The Mission

We’re building the AI that makes nuclear power actually deployable—collapsing licensing and delivery timelines from decades to years. Gordian, our platform, already accelerates work for utilities, advanced reactor companies, and major tech. We pair deep nuclear expertise with frontier AI and move with startup speed.

Now we need a Chief of Staff to turn momentum into machinery.

The Role (reporting to the CEO)

Not an EA. Not a scheduler. This is an IC-heavy role.

You’ll run the operating system of the company and remove friction from the work that matters most. Think 70% internal execution / 30% external orchestration with investors, clients, and partners like Accenture and hyperscalers.

Most weeks you’ll be building docs, systems, and processes yourself—then iterating them as we scale.

You will:

• Run the exec OS: set and maintain weekly plans, capture decisions within 24 hours, keep quarterly goals (OKRs) live and visible, surface risks/roadblocks early.
• Own cross-functional programs: from hiring blitzes to product/partner launches; keep the Gantt real, not pretty, and ship the artifacts (timelines, owners, checklists) that make it happen.
• Communicate like a star: spin ideas into investor updates, partner one-pagers, and external comms that don’t waste words.
• Coordinate hiring (not HR): calibrate roles, keep the funnel moving, organize interview loops, and land candidates quickly.
• Make compliance boring: drive completion of vendor security/IT questionnaires and light procurement processes so deals don’t stall.
• Instrument the business: take ambiguity and turn it into dashboards, trackers, and decisions—starting in Sheets/Notion, improving over time.
• Raise our profile: help run events, coordinate outreach to students and candidates, and be one of the operational “faces” of the business.

A sample week: close out quarterly strategy meeting action items; prep new-hire swag kits; cross-compare contract documents for a new client; run hiring stand-up; turn a founder’s brain dump into a crisp one-pager; unblock two team dependencies; publish the weekly plan.
