The Role

Our Business Analytics team is growing! We’re looking for an experienced Business Analyst to join our team in London on a 3-6 month contract.

In this role you will turn complex data into the insight that shapes how Quantum grows, owning business intelligence end to end and delivering real impact within your contract, from data warehouse structure to the Tableau dashboards leadership relies on to make decisions.

Key Responsibilities

• Own business intelligence development end to end and deliver against clear priorities within the contract.

• Build and maintain high-performance Tableau dashboards that leadership and operational teams use daily, optimising structure, data sources and user experience with the wider data team.

• Run the analysis that drives profit: cohort analysis, demographic segmentation, predictive value modelling, spend and cost management, and recommendation engines.

• Implement and manage tracking through Google Tag Manager, and support the development of our data warehouse structure.

• Partner with marketing, product and commercial teams to turn requirements into insight, and document your work so dashboards and BI tools can be handed over after the contract.

About You

• You thrive when working as part of a team

• Comfortable in a fast-paced environment

• Have excellent written and verbal English skills

• Last but not least, you’ll have no ego!
