Role Overview   We are seeking a   Senior Engineer / Architect   who knows that AI unlocks value only atop a foundation of trusted data and rich context. You will turn raw IT Ops data into layered, contextualized intelligence—enabling the shift from   descriptive to predictive to prescriptive   decisioning and autonomous agents. Owning the architecture end-to-end,   you'll   drive everything from   semantic modelling, ontologies, knowledge graphs, and knowledge bases   to   agentic context servicing (MCP Server & Gateway)   that exposes governed context to AI and BI solutions.

Key Responsibilities:   Own the   end-to-end architecture   spanning the Semantic, Data Context, and Context Servicing layers for enterprise IT data. Design and publish   ER models —defining entities, attributes, keys, grain, relationships, and cardinality in collaboration with stakeholders. Develop   ontologies , mapping business terms, DW tables from conceptual design to physical data models. Curate the   knowledge base   of reusable, governed business entities, semantic views, and BI-ready fields.

Architect and implement the   MCP Server and MCP Gateway   to expose governed context to AI and BI consumers. Build   LLM orchestration   capabilities, including synonym resolution, metric   selection , and entity resolution. Develop the   Query Translation Engine / SQL Generator   that converts natural-language questions into safe, governed, executable logic. Integrate the   Security Engine   to enforce access controls—row-level security, column masking, RBAC, and policy constraints—with full audit logging.

Proficiency   in Python,   PySpark   for semantic data processing, graph analytics, and AI-driven applications   Experience with RDF and OWL for semantic modelling and ontology development. Partner with   Data Governance, Risk, Security, and Compliance   to embed policies, controls, and audit trails across the context layers. Support   scenario-driven delivery , enabling agents to answer complex business questions with   accurate   facts and explanatory reasoning—the "what" and the "why."   Collaborate with and guide fellow team members   in building the semantic and context layers, providing technical direction, mentorship, and best-practice standards to uplift overall team capability.
