Lead AI Engineer, AI Productivity

Role Profile

Digital Operations, part of the LSEG Infrastructure & Cloud organisation, is seeking a Senior AI Engineer to build and scale AI Productivity Platforms across the enterprise.

This role will focus on hands-on engineering, integration, and operationalisation of enterprise AI platforms — ChatGPT, Claude, Microsoft Copilot and future GenAI capabilities — ensuring secure, scalable, compliant, and high-impact adoption across LSEG. The successful candidate will design and implement integrations, develop automation workflows, and embed AI capabilities directly into enterprise systems and business processes.

We are looking for a strong engineer with deep technical expertise in building AI-enabled systems and integrations from the ground up — including APIs, connectors, retrieval pipelines, agent frameworks, and automation tooling. The role requires hands-on experience across SaaS platforms, REST and event-driven architectures, scripting, identity integration, and secure enterprise development practices.

This role will play a critical part in driving measurable productivity improvements by embedding AI into engineering, operations, and corporate workflows across Markets, Data & Analytics, and Corporate functions.

This role will work closely with AI architects, platform leaders, and regional engineering squads, partnering with Cyber Security, Risk, and Infrastructure teams to ensure safe, governed, and scalable AI platform adoption.

Key Responsibilities

• Design, build, and maintain integrations between AI platforms (ChatGPT, Claude, Microsoft Copilot) and enterprise systems.

• Develop and deploy connectors, APIs, and automation workflows.

• Implement context management frameworks including MCP and support A2A communication patterns.

• Build and optimise RAG pipelines, including document ingestion and vector storage.

• Develop AI-driven automation solutions to improve productivity.

• Implement secure API integrations including authentication and data protection.

• Embed AI capabilities into SDLC processes and developer tooling.

• Implement guardrails such as prompt validation and data leakage prevention.

• Collaborate with architecture, security, and platform teams to meet enterprise standards.

• Monitor and optimize performance of AI systems.

• Contribute to experimentation and rapid prototyping.

• Support adoption through reusable components and templates.

Role Requirements

• Proven experience as a Senior Software Engineer or AI Engineer in an enterprise environment.

• Strong programming skills (Python, TypeScript or similar).

• Experience with enterprise AI/LLM platforms (ChatGPT, Claude, Microsoft Copilot).

• Solid understanding of LLM concepts (embeddings, prompt engineering, RAG).

• Experience building RAG pipelines and working with vector databases.

• Knowledge of MCP and/or agent-based architectures.

• Experience with REST APIs, webhooks, and microservices.

• Understanding of IAM (OAuth2, OIDC, RBAC).

• Experience implementing enterprise security controls and DLP.

• Familiarity with AI safety and guardrails.

• Experience with cloud-native development and containerisation.

• Strong debugging and system design skills.

• Ability to collaborate with senior stakeholders.
