Responsibilities

• Act as the senior analytical partner to the Finance team, owning the data and reporting layer that supports revenue reconciliation, monthly close, external audit, and revenue recognition across online and retail channels.

• Support annual budgeting, quarterly reforecasts, and rolling forecasts with data‑led scenario modelling and trading assumptions.
• Produce monthly P&L commentary and variance analysis in partnership with Finance, translating numbers into clear narrative for the SLT.
• Own finance‑facing reporting on inventory and stock value, working capital, refunds and returns, discount and promotion leakage, and ad‑hoc financial deep dives.
• Design and build the cross‑channel reporting framework that lets us compare, contrast and consolidate performance across online and retail stores.
• Develop channel‑level KPIs, benchmarks, and trading rhythms for an omnichannel business.
• Translate analytical findings into clear, actionable recommendations for senior stakeholders, including Finance Directors, CCO, and SLT.
• Line‑manage the Insights Analyst, owning their development plan, technical review, and day‑to‑day prioritisation.
• Champion best practice in SQL, data modelling, and BI development across the wider team.
• Act as a guardian of data accuracy, ensuring the integrity of finance‑critical and commercial numbers across the business.

• Strong Power BI skills, including DAX, data modelling, and dashboard design.
• Advanced Excel, including pivot tables, lookups, and financial modelling.
• Familiarity with Python (pandas, forecasting libraries) is a plus.

• Comfortable with Business Intelligence, Data Governance, and data modelling best practice.

• A strong track record of partnering with Finance teams on revenue, margin, forecasting, and P&L workstreams, while also delivering insight across customer, trading, marketing, and product.
• Demonstrable experience working across the full commercial breadth of an ecommerce or omnichannel business (customer, trading, marketing, product, finance), not just one area.
• Experience supporting external audit, revenue reconciliation, or working with finance directors on monthly close cycles is a strong advantage.
• Experience line‑managing or mentoring junior analysts is desirable.

Platforms

• Familiarity with bricks and mortar retail data structures (POS systems, stock and inventory flows across stores) is a strong advantage.
• Exposure to attribution platforms (e.g. Triple Whale), CRM platforms (e.g. Emarsys, Klaviyo), and marketing platforms (Meta, TikTok, Google) is helpful.

Mindset

• Strong commercial instinct, with the ability to think like both a finance partner and a trading analyst.
