Pay & Bill Business Analyst

Workwell are delivering a strategic, multi‑year programme to build an integrated global workforce platform. The programme aims to deliver efficiency through automations and integrates several back‑office systems across multiple geographies and business units. The Pay & Bill stream is central to this platform ensuring workers are paid correctly, clients are billed accurately, and the business has full financial visibility across multiple currencies and jurisdictions.

The Pay & Bill Business Analyst will be the analytical engine of the Pay & Bill stream. You will own the end‑to‑end requirements lifecycle from discovery and stakeholder workshops through to acceptance criteria, test support, and post‑delivery validation. Working closely with the Pay & Bill Delivery Manager, development teams, integration architects, and third‑party technology partners, you will ensure that business requirements are translated into precise, buildable, and testable specifications. This is a hands‑on, highly collaborative role requiring analytical rigour and the ability to navigate a complex, fast‑moving programme environment where multiple systems, teams, and stakeholders intersect. Remote role – travel to the London office as and when required.

What you’ll be doing:

• Lead requirements gathering globally across all Pay & Bill capabilities, ensuring all requirements are complete, traceable, and signed off before development begins.
• Facilitate structured discovery workshops with business and technical stakeholders to surface, challenge, and refine requirements across all workstreams.
• Produce and maintain high‑quality BRDs, functional specifications, process flows, data dictionaries, and user stories with clear, testable acceptance criteria.
• Own the Pay & Bill requirements backlog, managing traceability throughout delivery and evidencing outcomes at review points.
• Analyse current‑state pay and bill processes across business units, including legacy processes from mergers and acquisitions, identifying gaps, inefficiencies, risks, and compliance considerations.
• Design future‑state processes reflecting the target platform architecture, producing AS‑IS and TO‑BE process maps (including data flow maps) at the depth required for development and test teams.
• Identify and document all business rules governing payroll calculations, currency conversion, expense approvals, leave accruals, billing logic, and jurisdiction‑specific regulatory requirements.
• Lead the definition and documentation of the Pay & Bill Target Operating Model, mapping current‑state capabilities, identifying gaps against the target state, and translating TOM principles into actionable requirements and system specifications.
• Ensure integration decisions, system design choices, and workflow automations are continuously evaluated against the TOM, flagging deviations or technical debt risks before they are built in.
• Document and maintain all TOM artefacts, including operating model narratives, capability maps, RACI matrices, and process ownership definitions as living documents throughout the programme.
• Contribute to change impact assessments, working with the Delivery Manager and business stakeholders to identify operational changes at each phase of delivery.
• Define interface requirements between the time and attendance system, the core CRM platform, and the payroll aggregator, working closely with the integration and API team.
• Analyse data flows across systems, produce data mappings, and identify data quality issues that could affect payroll accuracy, billing integrity, or reporting.
• Contribute to data migration requirements where historical payroll or financial data needs to be transferred into new systems.
• Act as the day‑to‑day business liaison for the Pay & Bill stream, maintaining relationships with Finance, Payroll Operations, Client Services, and IT, and facilitating sign‑off on requirements and design decisions.
• Define test scenarios, UAT scripts, and acceptance criteria; coordinate UAT with business stakeholders; and conduct post‑deployment validation to confirm solutions meet requirements in production.
• Maintain accurate BA artefacts in line with the programme’s governance framework, identifying and flagging scope changes with clear impact assessments.
• Contribute to the stream RAID log, surfacing risks and assumptions that emerge through requirements and design analysis.
