Job Description: AI Architect - Infrastructure & Cloud

Title: AI Architect

Level: Senior Manager

Experience: 16-18 years

Role Summary

We are looking for an AI Architect to sit at the intersection of Infrastructure and Artificial Intelligence - someone who can design, build, and operationalize AI/LLM/Agentic solutions that solve real infrastructure problems: capacity planning, incident response, observability, automation, cost optimization, and resiliency engineering. This is not a pure research role - it's an applied engineering + architecture role for someone who can code, ship, and integrate AI into production infra workflows.

Key Responsibilities

• Architect and deliver AI/ML/LLM-based solutions embedded into infrastructure operations (ITOps/AIOps, self-healing systems, predictive capacity, automated RCA)
• Design and build agentic AI workflows (multi-step, tool-using agents) for infra automation - ticketing, monitoring, remediation, provisioning
• Evaluate, fine-tune, and integrate LLMs (open-source and commercial: OpenAI, Anthropic, Azure OpenAI, local/open models) into enterprise infra tooling
• Build RAG pipelines, vector databases, and knowledge-grounding systems over infra documentation, runbooks, and CMDB data
• Write production-grade code (Python primarily; scripting in Bash/PowerShell) - this role codes, doesn't just design PPTs
• Integrate AI solutions with cloud platforms (Azure/AWS/GCP), ITSM tools (ServiceNow), observability stacks (Datadog, Splunk, Prometheus/Grafana), and CI/CD pipelines
• Define and enforce AI governance guardrails - data privacy, model security, hallucination control, cost/token management
• Partner with infra leadership to identify high-ROI AI use cases and build the roadmap
• Mentor infra engineers on AI-adjacent skills; act as the internal AI Center of Excellence lead for the infra vertical
• Own POC → pilot → production lifecycle for AI initiatives, including MLOps/LLMOps practices

Must-Have Skills

• 16-18 years in Infrastructure/Cloud engineering or architecture, with the last 5-6 years focused on applied AI/ML/LLM work
• Strong hands-on coding ability - Python (must), API integration, SDK usage (OpenAI/Anthropic/LangChain/LlamaIndex)
• Solid understanding of LLM fundamentals: prompting, fine-tuning, embeddings, RAG, context windows, tokens/cost
• Practical experience building agentic AI systems (LangGraph, AutoGen, CrewAI, or custom orchestration) with tool-calling/function-calling
• Experience with vector databases (Pinecone, Weaviate, FAISS, Azure AI Search, etc.)
• Deep infra background: cloud architecture, networking, virtualization, ITSM, monitoring/observability, automation (Ansible/Terraform)
• Experience with MLOps/LLMOps - model deployment, monitoring, versioning, cost governance
• Strong architecture and solutioning skills - can whiteboard an end-to-end system and defend design tradeoffs

Good-to-Have

• Certifications: AWS/Azure/GCP AI or Solutions Architect
• Exposure to enterprise AI governance/responsible AI frameworks
• Experience presenting to CXO/leadership on AI strategy and business cases
• Prior experience in a Big 4 / GDS / large enterprise infra environment
• Open-source contributions or published POCs in AI/agentic systems

Soft Skills

• Ability to translate ambiguous infra pain points into AI-solvable use cases
• Strong stakeholder management - bridges infra teams, data science teams, and business
• Comfortable being hands-on (code/architecture) as well as strategic (roadmap, governance)
