Job Description
On behalf of our client, Affinity is seeking a technical SME for AI product engineering who defines technical standards, patterns, and guardrails for AI product development. You will establish rapid POC cycles to validate feasibility and inform production architecture, and provides technical oversight of vendor-led production implementations.
What You'll Do
Establish POC Cycle (30%)

• Build repeatable POC process enabling team to validate technical feasibility in

days before production investment

• Lead internal prototyping to prove concepts before production investment
• Create starter templates, reusable components, and AI patterns library (Skills,

Agents, MCPs)

• Document learnings to inform production architecture and vendor direction

Design Production Solutions & Set Vendor Direction (30%)

• Translate POC learnings into production architecture and technical specifications
• Design Azure integration patterns (AI Foundry, AI Search, ML, Fabric)
• Create detailed blueprints vendors execute from
• Define technical requirements: performance, security, scalability, monitoring

Technical Oversight & Risk Management (25%)

• Review vendor code and architecture to manage production implementation risks
• Ensure vendor solutions align with POC findings and architectural vision
• Conduct architecture reviews and identify risks early
• Internalize knowledge to reduce vendor dependency

• Enable team to become AI-native (Claude Code, AI-assisted development)
• Evaluate and adopt emerging AI tools and frameworks
• Collaborate with UX on design system implementation for vendor use

What It Takes

• Understanding of Model Context Protocol (MCP) architecture — how MCP

servers expose tools and data to AI clients, and how standardized tool integration
replaces custom point-to-point connectors in enterprise environments

• Familiarity with agentic patterns including MCP, function calling, tool use, and

orchestration frameworks (e.g., LangGraph, Semantic Kernel)

• Understanding of LLM limitations and strong judgment on when AI is (and isn't)

the right solution

• Exposure to function calling, tool use, and agent-to-agent interaction patterns in

production or experimental settings

• Ability to establish repeatable processes and patterns that enable team

velocity—you build systems, not just features

• Strong technical collaboration, code review, and documentation skills to guide

vendors and internal teams

• Practical experience with cloud platforms and DevOps practices (Azure AI stack,

CI/CD, Docker, Infrastructure as Code is a plus)

• Experience managing or providing technical oversight of vendor implementations

is a plus
Top Skills Necessary

• 5+ years of full-stack development experience, including 1+ years building production AI/ML systems with LLMs
• 3+ years of backend development experience, specifically designing and building REST APIs, handling state management, and architecting scalable services.
• 3+ years of front-end development expertise utilizing React, Next.js, TypeScript, and/or Tailwind CSS, with practical experience building design systems and component libraries
