Role Purpose
The role is the senior functional authority for a product or product area, responsible for defining how capabilities should work end to end and ensuring that the resulting solution is coherent, effective and fit for purpose. Working closely with Product Managers, Product Directors, Business Analysts, Engineering, Architecture, UX and other stakeholders, the role translates product strategy and business outcomes into high-level functional designs and Functional Requirements Documents (FRDs) that guide delivery. The role sits between product intent and detailed delivery, owning the high-level functional design that connects the two. It does not primarily own detailed specifications or user stories; these are elaborated by Lead/Senior Business Analysts and Business Analysts but an active steering role in elaboration is expected. During delivery, the role provides functional decision-making and design authority, resolving ambiguity, addressing cross-component conflicts and ensuring the product works coherently end to end from a functional perspective. LSEG Risk Intelligence increasingly uses AI and LLM-based capabilities both within its products and across the software delivery lifecycle. Experience in AI-enabled product design or AI-assisted delivery would therefore be advantageous.
Key Responsibilities
Functional Design

- Translate product goals into functional behaviours, boundaries, workflows and component interactions.
- Maintain a coherent end-to-end functional view across the product area.
- Identify dependencies, constraints, assumptions and integration points.
- Provide the design basis from which BAs and SBAs develop detailed specifications, stories and acceptance criteria.
Product and Solution Shaping
- Partner with Product Managers and Product Directors to shape capabilities and solutions.
- Challenge proposals where they create functional gaps, unnecessary complexity or adverse downstream impacts.
- Determine how product outcomes should be realised functionally.
- Assess cross-product impacts and contribute functional insight to prioritisation and roadmap decisions.
Functional Authority
- Act as the senior point of authority for functional questions.
- Lead and arbitrate cross-component functional decisions where requirements conflict, gaps emerge or delivery teams require clarification.
- Convene appropriate collaborators as an ad hoc functional design authority where required.
- Resolve ambiguity during development while maintaining alignment with the intended end-to-end design.
- Escalate significant product, architectural or business decisions where appropriate.
