Applied AI | Build the Brain 

Our client is building a system where AI doesn’t just generate answers - it reasons, validates, and defends them using structured evidence.

They’re hiring a Founding Agentic Reasoning Engineer to design and own the first real reasoning layer powering that system.

This is where complex questions get broken down, evidence gets challenged, and answers actually stand up to scrutiny.

What You'll Do

  • Architect multi-step AI reasoning workflows: from question → decomposition → retrieval → answer
  • Build tool-using agents that decide what to fetch, what to trust, and how to resolve conflicting data
  • Design systems that handle uncertainty, contradictions, and missing context properly
  • Combine internal structured data with external sources - and decide when each matters
  • Create reasoning traces that make system decisions transparent and debuggable
  • Build and iterate on benchmarks + evaluation loops that prove the system is improving
  • Turn one-off demos into repeatable, reliable workflows
  • Work closely with data teams to shape how evidence is structured for better reasoning

What They Want

  • You can take a messy, ambiguous question and break it into clear, solvable steps
  • Strong understanding of agentic / multi-step AI systems (retrieval, routing, synthesis)
  • You know where AI breaks - and how to fix it (not just patch it)
  • You think in terms of systems, not prompts
  • Comfortable working with uncertainty, conflicting data, and incomplete information
  • You can build and debug what you design

Nice to Have

  • Experience with RAG, knowledge graphs, or structured data systems
  • Exposure to evaluation frameworks, benchmarking, or human-in-the-loop setups
  • Familiarity with modern reasoning techniques (RL, distillation, etc.)
  • Background in high-stakes domains where accuracy and provenance matter

Why This Role

  • Own the reasoning layer of an AI system from day one
  • Work on problems where correctness actually matters
  • Shape how AI systems think. not just what they say

What it's Not

  • Not a pure research role
  • Not prompt engineering
  • Not a generic chatbot build
