Agentic AI Engineer (Boston, Hybrid)

Fairmarkit

Boston, MA • Remote

Full-time

Re-posted 11 days ago


Job description

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.

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

For this role you need to reside in Boston, MA. The annual compensation for this role is $336,000 -$350,000 (including a bonus), depending on experience and location, plus equity and benefits. This range is provided in accordance with applicable U.S. pay transparency laws. Final compensation will be determined based on experience, skills, and location. #LI-remote
