Senior Data Analyst – Data Delivery

This is a precision data delivery role — not a dashboarding or engineering position. You will own one of IWSR’s core data products end-to-end: ingesting, processing, and distributing it on a monthly cadence to senior external clients, while driving its ongoing modernisation. If you are energised by accurate, high-stakes data work — where getting it right every time genuinely matters — this role is built for you.

Please note: if your experience is primarily in Azure Data Factory, Databricks pipelines, or Power BI dashboard development, this role is unlikely to be a strong fit.

About IWSR: IWSR is the world’s leading source of data and intelligence on the global beverage alcohol market — trusted by Diageo, Pernod Ricard, AB InBev, private equity, and governments across 160+ markets. Now part of the WGSN group, we combine deep industry expertise with a fast-growing, collaborative team culture headquartered in central London.

What you’ll do:

• Own and deliver a dedicated data product on a monthly cycle — from raw ingestion through to client-ready output.
• Migrate Excel-based processes to SQL-based operations, dashboards, and scalable delivery frameworks.
• Troubleshoot and triage data quality issues with diligence and precision.
• Act as the primary point of contact for senior internal and external stakeholders on your product.
• Collaborate with data scientists and senior analysts to implement data-driven solutions.
• Document processes and implement best practices across the Data Delivery team.
• Keep pace with advances in data processing, analytics, and AI to continuously modernise delivery.

Essential skills – you must have these:

• Advanced Excel & VBA — evidenced in practice, not just listed on a CV.
• SQL — SQL Server, PostgreSQL or equivalent — querying, extraction, modelling, and manipulation of large datasets.
• Proven track record of owning recurring analytical outputs and delivering them accurately under deadline pressure.
• Comfortable working with large, repetitive datasets where precision is non-negotiable.
• Confident engaging senior internal and external stakeholders; able to translate data into clear business language.

Qualification:

Degree-level qualification in mathematics, statistics, data, or a numeric discipline. Applications without demonstrated Advanced Excel (VBA/Macros) and SQL experience will not be progressed.

Advantageous — these will strengthen your application:

• Python for data processing and automation (Pandas, NumPy).
• Experience in FMCG, market research, data intelligence, or commercial analytics environments with ETL design and tooling.
• Dashboard creation — Excel, Tableau, or equivalent front-end delivery.
• Knowledge of data warehouse fundamentals (star schemas, dimensional modelling).
• Familiarity with Databricks or cloud data platforms.
• Experience mentoring or developing junior analysts.

Benefits:

• 25 days holiday plus bank holidays and a company-wide end‑of‑year break.
• Hybrid working with flexible hours from our central London office and a 3‑week work‑from‑anywhere policy each year.
• Private medical insurance, pension, and regular social events.
• Strong learning and development opportunities within IWSR and WGSN.
• Access to a 24-hour employee assistance programme.
