Job description

Philadelphia area preferred. Mostly remote with visits to the PH office. US East Coast.

Philadelphia area preferred. Mostly remote with visits to the PH office.

Arbitr is the AI Context Platform. It understands a company's context (its rules, approvals, strategy and markets) and deploys agents that act on it to the right standard.

You'll build the engine that turns this new category into qualified pipeline. You won't do it by building a department. You'll do it as one person plus the agents you design, delivering what a team of three or four would.

What You'll Own

• Pipeline: You own the qualified pipeline number and the agent-run engine behind it.
• The category story: You shape how Arbitr describes the AI Context Platform to enterprise buyers, then turn it into messaging, positioning and content.
• AI Visibility: You run our AI Visibility pilots, and make sure Arbitr is the answer when buyers ask AI tools about our category.
• Channels, run by agents: Website, social, campaigns and content, carried out by agents you build and tune.
• Experiments: You run many small tests, cut what doesn't work quickly and scale what does.

How You'll Work With Atlas And RevOps

• Your agents take direction from Atlas and feed back every touch and result.
• You bring experiments to a weekly review with RevOps and the CCO.
• Pipeline definitions live in the platform, not in your team's spreadsheets.

Your first 90 days

• Days 1-30: learn fast. Sit with sales, customers and product. Audit the website, content and current lead flow. Agree pipeline targets with the CCO.
• Days 31-60: launch. Get your agent-run outbound engine live, ship a sharper category narrative and get the AI Visibility pilot running.
• Days 61-90: prove it. Show pipeline by channel through Atlas. Cut what's not working. Present a plan for the next two quarters, covering what your agents will take on next.

How We Measure Success

• Qualified pipeline created each quarter
• Coverage of next quarter's new-logo target
• Cost per qualified opportunity
• Conversion from first touch to opportunity
• AI Visibility pilots signed

About You

• You've built pipeline for a B2B SaaS or AI company, and you can show the numbers.
• You've built agents and automations that replaced manual work, and you can say what each one costs to run.
• You'd rather run ten small experiments than one big bet.
• You can tell a sharp story to enterprise buyers and connect it to revenue.
• You're fluent with data: CRM data, APIs and basic SQL. Attio experience is a plus.
• You want to be measured on results, and to grow your impact through what your agents do.

Bonus points: you've created or named a new category, or you've worked on how buyers find vendors through AI search.
