Agentic AI Engineer (Boston, Hybrid)

Fairmarkit•Boston, MA

34d•Hybrid

About The Position

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.

Requirements

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
Reside in Boston, MA

Nice To Haves

Experience with marketplace or PLG products
Startup or founder experience
