Digital Analytics Specialist

This is a role for someone who enjoys making data dependable and useful, not just producing dashboards.

You'll work with established eCommerce brands to build measurement foundations people can trust, turn performance data into clear commercial insight and solve complex tracking problems. Alongside specialists in CRO, SEO and Paid Media, you'll help clients understand what's happening, why it matters and what to do next.

You'll have the autonomy to make decisions, challenge assumptions and take ownership of client outcomes, not simply complete tracking tickets or compile reports.

Why join Proof3?

This isn't an agency where analytics ends with a monthly report.

You'll work across ambitious eCommerce brands, supported by specialists in CRO, SEO and Paid Media who actively use your work to improve performance rather than simply describe it.

You'll be trusted to shape measurement strategy, challenge clients constructively and focus on the data that matters: the data that improves decisions, customer experience and profitable growth.

You'll have variety without being treated as a reporting resource for everyone else. If you enjoy solving difficult problems, explaining them clearly and seeing your work influence what happens next, you'll fit right in.

How we approach data

At Proof3, we don't see data as a collection of dashboards, tags and platform metrics.

We combine sound measurement, careful implementation and commercial analysis to help clients make better decisions. Sometimes that means fixing a broken purchase event. Sometimes it means joining data from different sources. Sometimes it means showing that the apparent problem sits elsewhere.

Our approach starts with the business question and the decisions the data needs to support, not with a preferred tool or a standard reporting template.

We are clear about data quality and limitations, and we turn findings into practical recommendations. We measure success by the confidence and commercial impact our work creates, not the volume of reports we produce.

What you'll be doing

• Own digital analytics and measurement across a portfolio of multi-million pound eCommerce clients, ensuring data is accurate, reliable and supports commercial decision-making.
• Support CRO, SEO and Paid Media teams with robust measurement, focused analysis and actionable insights that improve client performance.

• Validate paid media tracking, consent management and privacy-related measurement across relevant advertising platforms.
• Lead measurement migrations and replatforming projects from discovery through to implementation, QA and post-launch validation.
• Build reporting dashboards and analyse customer behaviour, acquisition performance and commercial metrics to uncover meaningful opportunities rather than simply reporting results.
• Present findings and recommendations confidently to clients, adapting technical detail to suit both technical and non-technical audiences.
• Deliver data enrichment projects that improve reporting, analysis and marketing activation, while maintaining clear documentation, governance and implementation standards.
• Stay ahead of developments in analytics, privacy, AI and ecommerce measurement, applying new approaches where they'll deliver genuine value.
