About the Role

Concurrences is building the world's first AI research engine for antitrust law. We need someone with strong legal foundations who wants to own entire legal domains — designing what "correct" means, building the evaluation frameworks, and catching the subtle errors only a trained legal mind can spot. October 2026 production launch.

You'll work directly with our founder Nicolas Charbit (20 years building Concurrences into the definitive antitrust platform), our CTO Anton, and the wider Concurrences team of competition law partners and editors. Mentorship, feedback, and full access to Concurrences' 20-year case law database from day one.

Concurrences.com: The canonical antitrust platform since 2004. 100k+ articles, 20 years of case law, 120+ countries, ~50,000 professionals. Editorial board includes William Kovacic (former FTC Chair) and Mario Monti (former EU Commissioner). Now building Concurrences.AI — powering Claude, ChatGPT, and enterprise copilots to research competition law correctly.

What You'll Do

• Evaluate AI outputs for legal accuracy across jurisdictions — EU, US, French, Brazilian enforcement

• Build evaluation rubrics, annotation guidelines, and testing protocols for your legal domains

• Design instructions that help the AI reason about antitrust with precision, not generic legal chat

• Run structured experiments: "Find cases where precedent reversed." "Compare EU vs. US on vertical restraints."

• Own specific domains end-to-end — EU merger control, cartels, abuse of dominance — and shape the product roadmap from domain insight

• Write evaluation scripts using AI coding tools (no engineering background needed)

What You Have

• Law degree (JD, LL.B., or equivalent) with strong academic record. Antitrust coursework, thesis, research, or internship is a plus — but solid legal training combined with genuine interest in learning competition law is what matters most

• 0-2 years professional experience welcome, not required

• You've used Claude, ChatGPT, or another LLM and have a sense for where they struggle

• Strong English writing. French is a plus but not required

• You're curious about AI + law and want to be part of defining how AI serves legal research

Compensation

€1,200–€2,400/month depending on experience and output, paid in EUR via Wise. Independent contractor, monthly invoicing.

Fully remote. Async-first with regular mentoring sessions. Learn competition law and AI evaluation on the job — we invest in your growth. Start: ASAP.
