At Neptune, growth doesn't happen by accident. It's considered and engineered. We're looking for a commercially minded Marketing Analyst / CRM Analyst to help us do exactly that-turn data into decisions, and decisions into measurable growth. This isn't a reporting role. You won't be buried in dashboards. Instead, you'll work at the heart of our marketing team-identifying opportunities, designing experiments, and helping us understand what really drives customer behaviour across both eCommerce and physical stores. If you're someone who likes asking 'what if?' and proving it with data, you'll fit right in. This role is based at our stunning Support Office in Swindon, Wiltshire, full-time, 40 hours per week (Monday-Friday) with some hybrid working.
Job Responsibility:
Partner with marketing channel leads (paid search, paid social, CRM) to identify and unlock performance improvement opportunities
analyse campaign performance across the funnel to understand drivers of acquisition, conversion, and customer value
deliver clear, actionable insights that improve marketing efficiency and drive customer growth
design and evaluate experiments (including incrementality tests) to measure and optimise marketing impact
build and refine customer segmentation and audience strategies to improve targeting and engagement
analyse customer lifecycle behaviour to identify opportunities to increase retention, frequency, and lifetime value
use SQL and Python/R to interrogate data, investigate anomalies, and develop models that support optimisation and decision-making.
Requirements:
Strong SQL skills
experience using Python or R to analyse large datasets
familiarity with modern cloud platforms (GCP, Snowflake or Databricks)
solid grounding in experimentation and measurement including statistical testing, incrementality, and attribution modelling
ability to translate analysis into clear, actionable insight
experience analysing marketing performance across paid media and CRM, ideally within retail or eCommerce
understanding of lifecycle metrics like retention, frequency, and lifetime value.
