The role

We need a freelance social media marketer to grow Fulcra's reach and signups on X and LinkedIn among people who build with AI agents. You'll own engagement on those company accounts day to day, and work with content creator and our influencer program to turn creator posts into signups.

  • Type: Freelance / contract, remote
  • Time: About 15–20 hours a week (flexible)
  • Term: 3-month initial contract, with extension based on results
  • Reports to: Kristina Libby (marketing)
  • Works with: Liz, founders, product team
Who you'll reach

Our audience builds with AI agents every day and can tell marketing from a real setup at a glance.

  • X (developers, indie hackers and AI engineers running Claude Code, Codex, Cursor or OpenClaw, often several at once): agents losing context between sessions, agents overwriting each other's memory, handoffs between agents, real terminal-level demos
  • LinkedIn (engineering leaders, AI/platform teams, technical founders and early adopters inside companies): agents that share team context safely, permissions and data ownership, what actually works in production

They respond to builders showing real workflows. They ignore hype threads, listicles and "this changes everything" posts.

What you'll do
  • Join the conversations that matter: find and reply to builders posting about agent memory, context loss and multi-agent handoffs. Add something useful; don't pitch.
  • Turn product work into content: work with the team to make new features, agent-to-agent demos and user setups into posts.
  • Support the creator program: amplify partner posts, repurpose them (with permission), and flag new creators worth approaching to Liz.
  • Measure and report: track reach, engagement, profile visits, link clicks and signups each week, and double down on what converts.
  • Test paid boosts: with a small budget, test promoted posts on X and LinkedIn once organic winners are clear.
What success looks like

Success is measured in signups from builders, not in follower counts.

You might be a fit if

Must-haves

  • 2+ years growing B2B, developer or AI-tool audiences on X and LinkedIn, with examples you can show.
  • You use AI agents or coding tools yourself.
  • Sharp, plain writing: you can explain a technical idea in one post without jargon or hype.
  • Comfortable with analytics (X and LinkedIn analytics, UTM links) and reporting on what drove signups.
  • Self-directed: you can run accounts with light oversight and a weekly check-in.

Nice-to-haves

  • Short-form video or screen-recording editing for demos.
  • Experience working with creators or influencer programs.
  • Existing relationships in the AI builder community on X.
  • Familiarity with FTC disclosure rules for sponsored content.
How to apply

To apply, send the following to kristina@fulcradynamics.com:

  1. Links to 3 posts you wrote for X or LinkedIn that you're proud of, and why they worked.
  2. One account you grew, with before/after numbers.
  3. A draft X post or short thread introducing Fulcra to developers who run several AI agents (under 200 words).
  4. Your Fulcra ID.

Process: a 30-minute intro call, then a paid trial week (one week of drafted posts and replies), then the offer.

About Fulcra

Fulcra Dynamics builds the user-owned context backend for AI agents. Fulcra brings real-world data, recorded knowledge, files, and ongoing agent work into one owner-controlled context, helping agents know their users, know what's happening, work together, and become more helpful over time. People can carry that context across AI products, while organizations can use Fulcra as a governed context lake between agents and systems of record. Learn more at fulcradynamics.com.
