We're hiring for a very well-known loyalty and customer engagement business, trusted by some of the world's most recognisable financial services, travel and retail brands to design programmes that build genuine customer commitment. It's the rare kind of place that feels like a boutique agency, backed by serious corporate resource - fast-moving, autonomous, and genuinely fun to work in. The role You'll be the standalone Data Analyst for the Loyalty team not one of many, the one. That means real ownership from day one: extracting and shaping data from Salesforce Marketing Cloud and relational databases, building the monthly reporting suite, and turning raw numbers into commercial recommendations that actually get acted on. You'll get stuck into: * SQL querying (inner and outer joins - you'll need to be genuinely comfortable here) * Excel at a high level - pivot tables, formulae, slicing large datasets * Customer segmentation and propensity modelling * Lifetime value and uplift analysis * Helping shape what a brand-new loyalty programme could look like, working directly with a Loyalty Design Authority Who this is for This is a "doer" role. You won't have someone checking your work line by line - you'll need to be the kind of analyst who can pick up a brief, run with it, and come back with the answer, not more questions. If you like getting properly lost in the data and enjoy figuring things out yourself, this will suit you well. It's also a brilliant stepping stone if you're looking to build serious commercial and loyalty analytics experience fast, working alongside peers who love debating the best way to solve a problem. What you'll bring * Strong SQL and Excel skills, with experience handling large, complex datasets * Experience analysing customer, marketing or transactional data * Background in CRM, loyalty or lifecycle marketing analysis * Comfort building segmentation, propensity or CLV models * The confidence to work autonomously and manage shifting priorities * A collaborative, team-first mindset - this is not a lone-wolf role, even though you'll often be the only analyst in the room The details * Hybrid: 2 days per week in the office * Permanent, full-time ## Related Videos - [Beyond Dashboards: Fixing Text-to-SQL with Semantic RAG](https://www.wearedevelopers.com/videos/2036-beyond-dashboards-fixing-text-to-sql-with-semantic-rag) - [Alibaba Big Data and Machine Learning Technology](https://www.wearedevelopers.com/videos/37-alibaba-big-data-and-machine-learning-technology) - [How building an industry DBMS differs from building a research one](https://www.wearedevelopers.com/videos/768-how-building-an-industry-dbms-differs-from-building-a-research-one) - [Data Science in Retail](https://www.wearedevelopers.com/videos/586-data-science-in-retail) - [Data Analytics with Microsoft Fabric: End-to-End Use Case with Data Agents](https://www.wearedevelopers.com/videos/1547-data-analytics-with-microsoft-fabric-end-to-end-use-case-with-data-agents) - [Analytics in the Age of Agentic AI: A tour of ClickHouse and Langfuse](https://www.wearedevelopers.com/videos/100240-analytics-in-the-age-of-agentic-ai-a-tour-of-clickhouse-and-langfuse) ## Related Articles - [Data Analyst Salary in the UK](https://www.wearedevelopers.com/magazine/278-data-analyst-salary-in-the-uk) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Making Data Warehouses Fast: A Developer’s Story](https://www.wearedevelopers.com/magazine/107-making-data-warehouses-fast-a-developer-s-story) - [Data Analyst Salary Germany](https://www.wearedevelopers.com/magazine/277-data-analyst-salary-germany) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [Best Companies to work for in London: Top 25 Companies in 2023](https://www.wearedevelopers.com/magazine/187-best-companies-to-work-for-in-london-top-25-companies-in-2023)
