Agentic AI Engineer

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.

What You'll Do

• Architect and build AI agentic systems from the ground up that reshape how commerce operates
• Own end to end full stack development from front to back, infrastructure to interface, with AI first thinking throughout
• Design and build intuitive, AI native user experiences, not just backend logic
• Prototype quickly and iterate in direct collaboration with co-founders and early customers
• Partner with forward leaning industry leaders who are moving fast and expect the same
• Help define the technical foundation, stack decisions, and engineering culture for a scaling team
• Operate daily in the trenches with leadership, with high visibility, high ownership, and high impact

What You'll Bring

• Hands on experience building and deploying LLM powered applications or agentic systems in production
• Strong full stack engineering fundamentals across modern JS/TS frameworks, Python, REST/GraphQL APIs, and cloud platforms such as AWS, GCP, or Azure
• Experience with AI orchestration frameworks such as LangChain, LlamaIndex, AutoGen, CrewAI, or equivalent
• Strong product and design sensibility, with the ability to make good UX calls without a dedicated designer in the room
• The ability to move fast without sacrificing foundational quality: you know when to cut corners and when not to
• A founder mentality: you think about product, users, and business outcomes, not just tickets
• Comfort with ambiguity and zero to one environments where you're building the playbook, not following one

Bonus Points

• Experience with marketplace or PLG products
• Startup or founder experience
• Experience using AI coding tools extensively
• Experience with procurement, supply chain, or B2B commerce.
