Job description

Overview

As a Senior Data Analyst, you're passionate about using data to answer important business questions. You're not here to just build reports; you're here to build solutions. You thrive on solving problems that matter, working closely with teams across the business to translate messy challenges into models, insight and interactive data products that empower your colleagues to take action.

Responsibilities

• Be a Trusted Business Partner : Act as a true consultant to teams across the business to solve real commercial problems using data, building models and decision frameworks that help us answer tough questions and make confident calls.
• Champion Data-Driven Decisions : Help us move from instinct to evidence. You will design, run and analyse experiments (e.g. A / B tests) to measure the impact of our initiatives and prove what works.
• Turn Insight into Direction : Your insights are only as good as the change they drive. You will craft compelling narratives, demonstrating the "so what" behind every analysis.
• Build and Deploy Actionable Data Products : Go beyond dashboards. You will identify opportunities to operationalise data by designing, building and maintaining interactive applications and tools (e.g. using Retool). These products will empower teams to access, explore and act on data directly, improving efficiency and enabling self-service analytics.
• Help Shape Our Future : You will have the opportunity to contribute to projects applying machine learning to business challenges like customer churn, lead scoring and user segmentation.
• Share Your Knowledge : Contribute to our data culture by sharing your expertise, collaborating on projects and helping colleagues improve their analytical skills.
• Commercial Acumen First : You think about the business impact of your work and can connect data analysis to key performance indicators (KPIs).
• A Proven "Analytics Translator" : You have a demonstrated ability to bridge the gap between technical teams and business stakeholders. You can simplify the complex and articulate a clear, compelling story.
• Pragmatic & Outcome-Focused : You understand that done is better than perfect. You can lead multiple projects, fail fast and iterate quickly in a fast-paced environment, always with an eye on the final business outcome.
• Strong Analytical Capability :
• Excellent SQL skills for complex querying, data wrangling and performance optimisation.
• Proficiency in Python for data analysis.
• A solid grasp of statistical concepts, with hands-on experience in experimentation and A / B testing.
• Familiarity with data visualisation and application tools (e.g. Tableau, Retool)
• A Passion for What's Next : You have a demonstrable interest in emerging technologies like AI / ML and think creatively about how they can be applied to solve business challenges.
