Own the full-stack AI engineering and architecture foundation that powers Hexion's CaaS transformation. Design, build, and operate the enterprise AI platform - spanning data infrastructure, ML/LLM
pipelines, agentic systems, MLOps, and AI governance - that enables every domain (Commercial, R&D, Manufacturing, Supply Chain) to deploy production-grade AI at speed. 

• Define and own Hexion's enterprise AI architecture: multi-agent frameworks, LLM/GenAI platforms, ML pipelines, data
  layer, and integration patterns across SAP S/4HANA, Salesforce, OSIsoft PI, and cloud environments (Azure/AWS).
• Build and scale the agentic AI platform: multi-agent orchestration (LangGraph/CrewAI), RAG pipelines, tool-calling
  frameworks, guardrails, and human-in-the-loop controls for autonomous workflows across business functions.
• Establish and operate enterprise MLOps: model registry, CI/CD for AI, model versioning, drift monitoring, inference
  optimization, and closed-loop retraining pipelines - ensuring all models are production-grade and auditable.
• Architect the data foundation for AI: feature stores, semantic/vector layers, real-time streaming (Kafka/event-driven), data
  quality pipelines, and synthetic data generation for specialty chemicals use cases.
• Lead AI security and responsible AI engineering: prompt injection defense, model explainability (XAI), bias detection,
  access controls, and compliance with enterprise data policy and regulatory requirements (REACH, GHS, SOX).
• Serve as the technical authority connecting AI CoE, IT, domain teams (R&D, commercial, manufacturing), and external
  vendors - translating business requirements into scalable AI system designs.
• Evaluate and manage AI technology vendors, cloud providers, and open-source frameworks; make strategic
  buy/build/partner decisions for the AI stack with clear cost, capability, and risk analysis.
• Build and lead the AI engineering team: ML engineers, data engineers, LLM engineers, MLOps specialists, and AI
  platform engineers - hiring, mentoring, and creating a culture of engineering excellence.
• Champion engineering standards: modular/reusable AI solution patterns, API-first design, observability, SRE practices for
  AI systems, and documentation to accelerate cross-functional deployment.
• Drive Hexion's Perception Intelligence, Predictive Modeling, and Adaptive Closed-Loop Control capabilities - including
  sensor fusion from OSIsoft PI, digital twin integration, and process optimization AI for manufacturing.
• Own the AI infrastructure roadmap - balancing rapid experimentation and disciplined production delivery - and report
  engineering KPIs, platform reliability, and build-vs-buy decisions to VP/Director, AI Transformation (Sambit).

• 10+ years in AI/ML engineering, data engineering, or enterprise architecture; 3+ years in a senior technical leadership role owning an AI platform or engineering
  team.
• Deep expertise in GenAI/LLM systems: RAG, fine-tuning, prompt engineering, agentic frameworks (LangGraph, CrewAI, AutoGen), and multi-agent
  orchestration at enterprise scale.
• MLOps mastery: model lifecycle management, CI/CD for ML, drift monitoring, feature stores, model registries (MLflow, Kubeflow, SageMaker, Azure ML), and
  inference optimization.
• Cloud-native AI infrastructure: Azure/AWS AI services, containerized ML workloads (Docker/Kubernetes), event-driven architecture (Kafka), APIs, IaC, and
  observability/SRE practices.
• Data architecture for AI: feature engineering, vector/semantic layers, real-time streaming, data quality pipelines, and integration with industrial systems (OSIsoft
  PI, SAP S/4HANA, Salesforce or Dynamics 365).
• Responsible AI engineering: XAI/explainability, bias detection, prompt injection defense, AI security, and compliance frameworks relevant to specialty chemicals
  (REACH, GHS, data sovereignty).
• High level of  proficiency with ERP and advanced planning systems (SAP IBP, S/4HANA, APO, o9, Kinaxis).
• Python/SQL fluency; working knowledge of ML frameworks (PyTorch, scikit-learn, HuggingFace); ability to review and contribute to production AI code. (Preferred)
• Prior experience building AI teams from the ground up in transformation-stage or industrial enterprises; track record of hiring and growing ML engineers and data
  engineers. (Preferred)
