We're looking for a Marketing Manager to run social, content, and campaigns across Mercor's marketing team.
You'll be hands-on across all of it, owning programs end to end from brief to launch to results.
This role suits someone early in their career who wants range and ownership.

Plan and run integrated campaigns across email, social, web, and events, from the brief through launch and reporting.
Run Mercor's presence on X and LinkedIn, track what AI researchers, founders, and VCs are talking about, and turn launches, research, and news into moments that take over the feed.
Drive distribution for the podcast, including the launch plan and social clips for every episode.
Write blog posts, emails, landing pages, and launch assets that meet a high quality bar.
Manage owned channels and marketing site updates, write and ship new landing pages, and run experiments.

2-4 years of marketing experience, ideally at a startup or high-growth company.
You live on X, follow AI researchers, VC and tech enthusiasts on X, and know what drives conversation.
You've run social for a brand or grown your own account.
You're an excellent writer and editor who can write for both technical and business audiences.
You have hands-on experience across more than one channel or area (content, email, social, events, web).
You use AI tools every day and have built at least one workflow or automation that saves time, but don’t rely on it for your writing.
You're scrappy and adaptable, thrive in ambiguity, move fast, and are comfortable with changing priorities.
You're organized, detail-oriented, and can run several programs at once without dropping anything.
