Project Coordinator

What you'll do

This is the operations seat on an AI training-data program. You would sit between a leading AI lab's program leadership and the domain experts who produce its data, and keep the machine running.

The ad's list, grouped:

• Translating direction: take input from leadership, turn it into clear guidelines, and get it to the expert teams; help write and refine project guidelines with research and product partners
• People: onboard and support new experts as the program grows
• Quality: spot quality issues, work out root causes, and share what you find across teams
• Cadence: attend weekly business reviews, keep notes and action items, lead calls when needed, flag roadblocks early
• Tracking: manage deliverables in Google Sheets and Excel

If you have worked as an annotator or expert contributor and wondered who writes the guideline updates and chases quality regressions, this is that job.

Who fits

• US-based (a hard requirement)
• 3+ years in project coordination or management, including large cross-functional teams
• Hands-on AI training-data or human-data project experience, as a coordinator, team lead, EPM or expert contributor
• Strong data management (Excel, SQL) and working knowledge of coding
• People management experience or proven ability to lead large groups
• A STEM background is strongly preferred

The ad names prior AI data program coordination at companies like Meta, TikTok or Amazon, or EPM and project-lead experience on Mercor projects, as the ideal.

Employment terms

This is a full-time W-2 employment position with Cincinnatus LLC, a staffing company that acts as employer of record and places staff within client teams. Cincinnatus handles payroll, benefits and compliance. That makes it structurally different from most Mercor listings, which are independent contracts.

Payment cadence and method are not published on the listing, and the ad does not mention the usual visa exclusion.

What it pays

$45–55 per hour. At full-time hours that is roughly $94,000–114,000 a year before tax, if hours are steady; the ad does not state guaranteed hours.

Worth knowing

Good:

• W-2 employment with benefits, not a contractor gig
• Direct placement inside an AI lab's GenAI team
• A natural step up for experienced annotators and Mercor project leads

Less good:

• US-only
• Requires both coordination experience and AI data experience, plus SQL and some coding
• The lab and the benefit package are not named
• Full-time schedule, so it cannot sit alongside another job
