About the role

Role Overview

Direct-hire, fully remote AI roles with U.S. mid-market companies. You’ll build AI systems that move beyond demos into production and remain reliable under load.

Two Role Tracks

AI Developer (Developer Track)

  • Build LLM-powered applications and agentic systems
  • Use model APIs (e.g., Claude, GPT)
  • Implement retrieval (RAG) with vector databases
  • Develop with agent frameworks, tool use, and orchestration
  • Integrate AI into a real product or operational workflow

AI Engineer (Engineer Track)

  • Own training and fine-tuning
  • Build model serving and inference systems
  • Implement MLOps, pipelines, and operational tooling
  • Provide infrastructure that keeps models fast, reliable, and affordable at scale

Responsibilities

  • Deliver production-ready AI systems that real users/operations rely on
  • Make and defend technical architecture/trade-off decisions
  • Produce clean, maintainable work the client team can operate after you ship

Requirements

  • Proven experience: you must have built and shipped complex AI systems to production
  • Ability to walk through your most complex personally built AI system: purpose, your role, hardest technical decision, and how you verified it worked
  • Strong engineering fundamentals with real code (not demo-only work)
  • Track-specific production experience:
    • Developer Track: LLM APIs, RAG, vector databases, agent frameworks
    • Engineer Track: training/fine-tuning, model serving, MLOps, scaling
  • Ability to explain verification/validation methods and communicate to both engineers and executives
  • Traits: independent, results-driven, detail-oriented, dependable, self-motivated

Nice-to-Haves

  • Demonstrated judgment in making hard technical calls and verifying system behavior
  • Experience integrating AI into existing products/workflows
