As part of our AI@LSEG Product Management team, we are seeking a Senior Product Manager with deep expertise in testing, automation, and evaluation systems to own our AI Evaluation Framework for the entire AI workflow from natural language requests to the execution to the response.
This role will define how LSEG measures the accuracy, reliability and consistency of AI-powered interactions across our data, analytics and market solutions. You will establish the frameworks, processes and standards that evaluate LLM behaviour, MCP tool usage, and natural-language output quality across multiple AI stacks—ensuring our customers receive precise, trustworthy, and explainable results.
Key Responsibilities & Accountabilities
Framework Ownership
Design and own the end-to-end evaluation framework for AI systems: natural-language prompting, LLM orchestration, MCP execution, and natural-language output quality.
Codify a rubric-based scoring system covering task fulfilment, factual accuracy, reasoning quality, safety, coverage and instruction adherence.
Develop the taxonomy for query types, complexity levels, and evaluation profiles across all LSEG MCPs and AI stacks.
Test Design & Automation
Partner with SMEs to create seed evaluation scenarios, and define the processes for generating structured prompt permutations using LLMs.
Build the strategy for scalable automated evaluation pipelines, including LLM-based graders, confidence scoring, sampling strategies and regression detection.
Define requirements for internal tooling: scenario catalogues, result dashboards, model-versus-model comparisons, performance tracking and release gates.
Cross-Functional Leadership
Collaborate with product teams across Data & Analytics, Markets, FTSE Russell and Risk Intelligence to integrate the evaluation framework into their AI initiatives.
Work closely with Engineering, AI Governance, Model Risk, Compliance and GSSR to ensure alignment with responsible AI standards and regulatory expectations.
Support product teams in interpreting evaluation results, identifying failure modes and improving model + MCP reliability.
AI Strategy & Governance
Contribute to group-wide AI governance by defining evaluation requirements that support responsible AI, explainability and bias mitigation.
Provide insights on emerging testing and benchmarking methodologies across the AI ecosystem.
Ensure evaluation frameworks adapt as LLMs, MCPs and customer workflows evolve.
External & Internal Advocacy
Serve as the internal subject matter expert for AI evaluation and testing.
Present evaluation insights to senior stakeholders, ExCo, product leadership and external partners.
Skills & Competencies
Required
Background in product management, QA/test automation, or ML evaluation frameworks with experience designing structured test systems at scale.
Strong knowledge of LLMs, prompt engineering, and tool-augmented LLM workflows.
Experience with test automation, scenario design, evaluation metrics and quality frameworks in complex systems.
Familiarity with financial data, analytics workflows, or MCP-style interoperability.
Ability to translate ambiguous real-world user tasks into formal evaluation structures and rubrics.
Preferred
Experience with LLM-based evaluators, rubric scoring systems, structured data validation, and regression frameworks.
Familiarity with financial data pipelines, structured/unstructured data handling, analytics APIs, and Python/JS-based tooling ecosystems.
Strong analytical skills: ability to identify quality gaps, failure patterns and reliability issues in AI systems.
Comfortable partnering with senior internal stakeholders, engineering teams and policy groups.
Measures of Success
Quality & Accuracy
Improvements in task fulfilment accuracy, reasoning clarity and factual correctness across MCP-powered workflows.
Reduction in hallucinations, constraint violations, and output variability across permutations and AI stacks.
Scalability & Adoption
Uptake of the evaluation framework across LSEG product divisions.
Level of automation achieved in test execution and evaluation pipelines.
Stability of evaluation results and speed of identifying regressions.
Organisational Impact
Contribution to Responsible AI, model risk processes and governance frameworks.
