As a Measurement & Growth Science Lead within Next Lab, you will play a critical role in shaping how effectiveness, testing and measurement best practice is defined and embedded across the Sky account.

Sitting within the Measurement & Growth Science team, you will report into the Measurement Lead, while working extremely closely with Media Planning, Vertical Planning teams and Digital Leads. Your role is to act as a strategic partner and technical challenger; ensuring that experimentation, measurement design and data foundations are robust, practical and decision‑led.

This is not a pure analytics role, nor a traditional planning role. Instead, it requires someone who can:

• Zoom out to understand the full media ecosystem and business context;
• Zoom in to challenge how tests are designed, how data is structured, and whether measurement approaches will genuinely answer the questions being asked.

You will help ensure that Sky’s investment in media is underpinned by clear learning agendas, high‑quality experimentation, and trusted sources of truth, while enabling planning teams to move faster and more confidently.

• Act as a partner to Sky stakeholders and Publicis planning teams on measurement, effectiveness and test‑and‑learn strategy.
• Shape and challenge experiment design (e.g. incrementality studies, conventional tests, controls and splits), ensuring approaches are feasible, statistically sound and decision‑useful.
• Partner closely with Vertical Planning teams and Digital Leads to embed best‑in‑class testing practices across Brand and Performance activities.
• Support the definition of learning agendas – ensuring tests are connected to clear business questions rather than activity for activity’s sake.

• Act as a bridge between measurement teams, media planners and channel specialists, translating technical considerations into practical planning implications.
• Serve as an active thought partner – confidently challenging assumptions and helping teams stress‑test ideas before they go live.
• Support Digital Leads and Vertical Planning teams by providing clarity on what good looks like when it comes to effectiveness and testing.
• Contribute to the development of shared ways of working, templates and playbooks that improve consistency across teams.

• Support the ongoing standardisation of measurement frameworks, trackers and reporting processes, working alongside Next Lab colleagues and planning leadership.
• Help document and codify best practice (e.g., “Best practices for implementing Brand Lift Surveys to support your measurement strategy”), ensuring knowledge is transferable and scalable.
• Identify gaps in capability or process and help shape solutions that improve speed, quality and confidence across the organization.

• Champion initiatives that improve data integrity, consistency and clarity, including:
• Single Source of Truth for spend and planned budgets.
• Conversion tracking and reporting consistency.
• Alignment between platform, ad‑server and first‑party data.
• Help simplify complex data…
