Key Responsibilities

• Design and Build Agentic Analysis Workflows
  
  

Design long-running, multi-stage analytical workflows using AI agents that can pause, resume, and recover without losing work.

Orchestrate LLMs and tools including retrieval, calculations, rules, and structured extraction into reliable and traceable workflows.

Engineer prompts and structured-output contracts to ensure validated, machine-usable outputs.

Build on event-sourced service frameworks (e.g., Akka SDK) where state, decisions, and evidence are persisted throughout the workflow.

• Build and Operate the Knowledge Graph
  
  

Design and maintain a knowledge graph that stores entities, relationships, and provenance extracted from source content.

Build ingestion and extraction pipelines that transform raw documents into validated, queryable graph structures.

Ensure every fact is traceable to its source.

Implement graph-based and vector retrieval techniques, including GraphRAG and embeddings, to provide grounded responses.

• Expose Capabilities Through Open Agent Interfaces
  
  

Develop Model Context Protocol (MCP) tool servers and agent-to-agent (A2A) interfaces.

Integrate with MCP-compatible clients and low-code agent platforms, including Microsoft Copilot Studio agents.

Build conversational interfaces that answer questions strictly from grounded knowledge graph data.

• Establish Grounding, Evaluation, and Safety Standards
  
  

Implement anti-hallucination controls ensuring outputs are supported by cited sources.

Build Automated Evaluation Frameworks, Including

Section-level scoring

Regression testing

Edge-case coverage

Human-review rubrics

Implement guardrails for prompt injection, data minimization, and safe output generation.

Incorporate human-in-the-loop checkpoints and governance evidence required for AI reviews.

• Production Deployment and Operations
  
  

Own the full path from development through production deployment.

Build and maintain CI/CD pipelines, environment configurations, secrets management, and access controls.

Work With Enterprise AI Platform Services, Including

Managed model endpoints

Search and retrieval services

Document storage

OCR/document intelligence solutions

Graph databases

Implement logging, metrics, tracing, monitoring, and alerting to support production operations.

Preferred Background

Experience delivering enterprise-scale AI systems in production environments.

Experience integrating AI capabilities into business workflows and customer-facing experiences.

Strong collaboration skills with both technical and business stakeholders.

Passion for innovation, continuous improvement, and responsible AI practices.
