Our partner is a fast-growing applied AI company that builds high-quality reinforcement-learning environments, agents, and data sold to the world's leading frontier AI labs. They recently grew from under twenty people to more than fifty in a matter of months and have reached a nine-figure revenue run rate. Their work directly powers foundation-model development across the industry.

• Strong Python, plus experience with Next.js or a comparable modern web framework.
• A track record of owning projects end to end and shipping quickly in a fast-paced environment.
• Background at a top-tier tech company, financial institution, or high-growth startup; data infrastructure for AI/ML systems is a plus.
• A track record of meaningful tenure and impact at previous companies.
