Performics UK is the performance marketing arm of Publicis Media, committed to exceeding business goals by blending Data, Tech, Ops, and Talent to accelerate performance impact daily. With over two decades of experience, we harness technology and innovation to generate and convert consumer demand across search, social, display, and commerce channels. Embracing a deep understanding of consumer intent and behaviour, we thrive on data-driven insights, guiding our planning and optimisation processes through rapid trials, real-time enhancements, and intelligent analytics.

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

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.

Responsibilities
  • Act as a partner to Sky stakeholders and Publicis planning teams on measurement, effectiveness and test-and-learn strategy.
  • Shape and challenge experiment design, 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 pressure-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.
  • Help document and codify best practice, ensuring knowledge is transferable and scalable.
  • Identify gaps in capability or process and help shape solutions that improve speed, quality and confidence across the organisation.
  • Champion initiatives that improve data integrity, consistency and clarity.
  • Help simplify complex data landscapes without losing meaning, balancing granularity vs. usability for decision-makers.
Qualifications
  • Experience in a measurement, effectiveness, strategy or growth-focused role within media, consulting or a complex client environment.
  • Strong understanding of media experimentation and test design, including incrementality, attribution considerations and performance measurement.
  • Hands-on experience from at least one paid media channel background, with an appreciation of how channels interact.
  • Ability to challenge measurement approaches constructively, balancing technical rigour with commercial pragmatism.
  • Strong stakeholder management skills, with confidence working alongside senior client and agency leaders.
  • Excellent communication skills - able to translate complex measurement concepts into clear, actionable guidance.
  • A critical thinker with a proactive, solutions-oriented mindset.
Will Ideally Have
  • Experience working with or alongside Growth Science, Analytics or Marketing Science teams.
  • Familiarity with measurement approaches such as attribution, MMM, brand lift studies, incrementality testing and learning agendas.
  • Exposure to large, complex advertisers.
  • Experience contributing to data standardisation, reporting frameworks or operational best practice.
  • Interest in how emerging tools, AI and automation can enhance measurement and experimentation.
