Job description

Role Overview:

We are looking for a Data Analyst to join One Retail Group and play a critical role in bringing structure, clarity and trust to our data. Operating within an online retail business that sells primarily through Amazon FBA alongside additional ecommerce channels, this role is central to how we understand performance and make decisions as we scale. Our data today lives across multiple systems and tools, and while it is rich, it is often fragmented. Your role will be to turn this complexity into clear, consistent and reliable reporting that teams across the business can depend on. You will design, build and maintain impactful Power BI dashboards that support commercial, operational and performance decision making. Sitting within the IT and Data function and reporting to the Head of IT, you will work closely with stakeholders across Buying, Operations, Warehouse, Logistics, Finance, Customer Experience and Marketing. This is a hands‑on role with real ownership, where you will be encouraged to deeply understand our end‑to‑end business model and reflect it accurately in the reporting you deliver. As the function matures, there is scope to grow responsibility for key reporting areas and become a trusted owner of core business metrics.

Key Responsibilities:

Data Integration & Management:

• Bring together data from a wide range of internal and external sources including Microsoft 365 tools, Dynamics 365 Business Central, Microsoft Fabric, Power BI, spreadsheets, and third‑party cloud platforms covering purchasing, logistics, sales and finance.
• Work confidently with imperfect, inconsistent and evolving datasets, applying logic and structure to improve usability and reliability.
• Validate and reconcile data across systems, ensuring alignment between sales, stock, dispatch, finance and returns.

Reporting & Dashboard Development:

• Design, build and maintain Power BI dashboards used across the business to track commercial, operational and performance metrics.
• Develop and maintain consistent KPI definitions, creating a single version of the truth that teams can rely on.
• Transform and model data using Power Query, DAX and related tooling to support scalable, efficient reporting.
• Ensure dashboards are intuitive, actionable and clearly aligned to how teams actually operate.

Stakeholder Collaboration & Insight:

• Work closely with stakeholders across Buying, Operations, Warehouse, Logistics, Finance, Customer Experience and Marketing to gather requirements and understand reporting needs.
• Translate business processes into meaningful metrics that reflect real performance and outcomes.
• Support ad‑hoc analysis requests and convert recurring needs into automated, standardised reporting wherever possible.
• Explain data, metrics and insights clearly to non‑technical stakeholders, building confidence and trust in reporting.

Process Improvement & Automation:

• Reduce reliance on manual spreadsheet reporting by improving automation, structure and standardisation.
• Document reports, datasets and metric logic to ensure continuity, transparency and long‑term trust.
• Proactively identify opportunities to improve data quality, efficiency and reporting workflows.
• Take ownership of issues through to resolution rather than working around problems.

Ideal Candidate:

• 2 to 5 years’ experience in a Data Analyst or similar role, ideally within a fast‑paced commercial environment.
• Strong experience building dashboards in Power BI, including data modelling and DAX.
• High level of competence with Excel and spreadsheet‑based analysis.
• Comfortable working with data from multiple sources and navigating ambiguity or inconsistency.
• Exposure to online retail or ecommerce data environments is an advantage, but not essential.
• Able to understand end‑to‑end business processes and translate them into clear, relevant metrics.
• Confident working with both technical and non‑technical stakeholders across multiple departments.
• Strong attention to detail, with a genuine care for data accuracy and reliability.
• Curious, business‑focused and motivated to understand how the company really operates.
• Proactive, ownership‑driven and keen to grow responsibility over time rather than remain task‑focused.
• Practical, hands‑on and improvement‑oriented, with a mindset aligned to spending mindfully and delivering real value.
