## About the Role

* Experience owning architecture artefacts in a governed enterprise.

## Description

The team operates a Central MCP Delivery model: building critical MCP tools and services "for" product teams where required, while simultaneously defining standards, patterns, and platform capabilities that allow teams to progressively move towards self-service contribution.

LSEG AI Assist / Internal MCP Programme of Work

This programme delivers an LSEG-owned, production-grade agentic AI platform with MCP as its extensibility layer.

The scope of work includes:

 * Building and operating LSEG AI Assist, an in-house agentic experience capable of reasoning, planning, and tool-calling.

 * Operating QAS, the enterprise RAG and search layer used to ground agent responses in approved data sources.

 * Delivering a production Internal MCP Gateway providing discovery, security, policy enforcement, observability, and lifecycle management for MCP tools and Skills.

 * Designing and building MCP servers and Skills that expose internal and vendor systems safely to agents.

 * Establishing evaluation, quality control, and governance mechanisms so MCP tools and Skills can be promoted through PTB/PTO and operated with confidence at scale.

The programme follows a "build for" model today, with a strong emphasis on defining the future product and platform experience, patterns, and contribution pathways that will enable federated scale over time.
