Responsibilities
- 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
- Functional Design:
- Define and own high-level functional designs, FRDs and component scope
- 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
- Delivery and End-to-End Coherence:
- Provide functional direction and clarification to BAs, SBAs and engineering teams throughout delivery
- Review detailed specifications to ensure alignment with the intended functional design
- Participate in design reviews, refinement oversight and delivery governance
- Identify inconsistencies across components, teams and requirements and drive resolution
- Balance immediate delivery needs with longer-term product coherence and maintainability
- Leadership:
- Provide functional leadership and guidance to Business Analysts and Senior Business Analysts
- Mentor analysts and support development of functional analysis and design capability
- Promote consistent approaches to functional design and decision-making
- Where applicable, provide day-to-day leadership to a small analyst team while remaining primarily focused on functional ownership
- Success is demonstrated through:
- Clear and coherent functional designs that enable effective delivery
- Strong alignment between product intent, detailed requirements and delivered functionality
- Fewer functional gaps, conflicts and late-stage surprises
- Faster resolution of cross-component functional decisions
- Improved consistency of functional analysis across teams
- A product that works coherently end to end rather than as a collection of individually delivered features
Requirements
- Experience in AI-enabled product design or AI-assisted delivery would be advantageous
- Demonstrated experience defining high-level functional designs for complex or highly integrated products
- Significant experience in business analysis, functional analysis, product analysis or a related field within complex software environments
- Experience making or facilitating decisions across multiple components and delivery teams
- Strong analytical and problem-solving skills, particularly where requirements are incomplete, conflicting or ambiguous
- Ability to translate product strategy into clear functional direction
- Strong understanding of how software components and capabilities interact end to end
- Ability to influence senior stakeholders and challenge proposed solutions constructively
- Experience working across Product, Engineering, Architecture and Business Analysis
- Previous experience as a Lead, Senior or Principal Business Analyst
- Experience mentoring or leading analysts
- Experience with enterprise-scale, platform or highly integrated software products
- Familiarity with Agile delivery and AI-enabled product development
