Lead Architect – AI Enablement & Automation (.NET)

Company Description

Job Description

We are seeking a highly experienced Lead Architect – AI Enablement & Automation (.NET) to drive the AI transformation of our client’s engineering organization.

This role combines enterprise-level architectural leadership with hands-on AI automation delivery.

The architect will operate across two strategic pillars:

1. Enablement – Establish scalable AI foundations that empower .NET engineering and QA teams.
2. Automation – Design and deploy production-grade AI-driven agentic workflows solving high-value business problems.

Key Responsibilities

1. Enablement Pillar – Scaling AI Adoption Across Engineering

Enterprise AI Architecture

• Define and implement architectural guardrails for AI integration within .NET 8/Core microservices.
• Establish standards for secure, scalable, and cost-efficient AI consumption.

Shared AI Infrastructure

• Design and develop a Common AI Service Layer using frameworks such as Semantic Kernel or LangChain.NET.
• Implement centralized capabilities including:
  • Authentication & secure API access
  • Rate limiting & throttling
  • Cost tracking & observability
  • Model routing & fallback strategies

Developer Acceleration

• Build reusable NuGet packages, SDKs, and frameworks to standardize AI integration.
• Create project templates and CI/CD pipelines enabling teams to deploy AI-enabled modules as easily as standard Web APIs.
• Embed AI best practices into engineering workflows.

Upskilling & Mentorship

• Lead a Community of Practice (CoP) for AI adoption.
• Mentor C# engineers in:
  • Vector search concepts
  • Prompt engineering
  • RAG patterns
  • LLM orchestration & tool usage
• Drive technical governance and AI engineering standards.

2. Automation Pillar – Proven AI Delivery at Scale

Agentic Workflow Design

• Architect and implement multi-agent systems capable of:
  • Executing complex business logic
  • Interacting with legacy systems and databases
  • Performing autonomous task orchestration

Production-Grade RAG Implementation

• Build advanced Retrieval-Augmented Generation (RAG) systems using:
  • Hybrid Search (Vector + Keyword)
  • Semantic re-ranking
  • Data chunking & partitioning strategies
• Deliver high-accuracy AI-driven support and automation systems.

AI Reliability & Operational Excellence

• Implement enterprise-grade reliability mechanisms:
  • Retry policies
  • Fallback models (e.g., GPT-4 → Phi-3 or equivalent)
  • Hallucination detection & validation frameworks
• Define observability standards for latency, cost, and accuracy.

Performance & Cost Optimization

• Optimize token consumption and inference latency.
• Implement semantic caching strategies.
• Tune memory and concurrency management within the .NET runtime.
