The Role

Fairmarkit is building a brand new AI and Agentic business line from scratch, and we're assembling a small, elite founding team around it. This is one of the first two technical hires on this venture. You'll work directly with co-founders Kevin Frechette and Victor Kushch every day, with zero bureaucracy between your work and real company impact.

We're looking for builders: current, former, or future founders who want to architect something massive from the ground up. You need to already be deep in AI, shipping, experimenting, and living it daily. You should also have a strong eye for product and design, since you'll be shaping not just how this system works but how it looks and feels to use.
