Make an impact!

As a senior data science leader, your primary focus is to own measurement strategy and drive business impact by connecting rigorous data science with strategic business decisions.

• Translate complex findings into clear, compelling narratives for C-suite and senior leadership to guide multi-million dollar budget decisions
• Drive cross-functional partnerships across marketing, finance, engineering, and data teams to implement measurement frameworks and ensure adoption
• Influence stakeholders at all levels to adopt data-driven decision-making and shape how the organisation measures marketing ROI among channel managers, advertising partners, senior leadership, finance, and data engineers.
• Promote measurement best practices and establish standards within the organization; stay current with industry advancements in experimentation, attribution, and measurement
• Mentor and raise the bar for analytics capabilities within the team and contribute to advancing the analytics discipline
• Operate with independence and ownership: take initiative on ambiguous problems, drive solutions to completion, and demonstrate strategic judgment in prioritizing high-impact work

Experience and qualifications:

• Relevant degree in a quantitative discipline (Mathematics, Data Science, Engineering, Statistics, or related field) OR minimum 3+ years of experience in analytics, data science, or a related analytical role
• Experienced in measuring marketing effectiveness and channel ROI such as incrementality testing, marketing mix modeling (MMM), cleanroom, or other marketing measurement method or frameworks
• Demonstrated capability to independently frame ambiguous business problems into data science solutions within marketing analytics and drive end-to-end processes from data extraction to insight implementation
• Strong proficiency in SQL, Python, and Tableau for data extraction, analysis, modelling, and visualisation. Hands-on expertise applying statistical methods and experimentation techniques, including A/B testing, user-level testing, and causal analysis
