Job Description

What You’ll Do

Own Data Science end‑to‑end for a specific market or industry across new and established products, including analytical design, methodology decisions, and solution validation.

Act as a senior Data Science business partner to Managing Directors, Commercial, Product, and Technology leaders, supporting country‑level revenue, EBITDA, and strategic objectives.

Engage directly with external clients in high‑pressure situations, translating complex and often ambiguous business problems into robust analytical strategies, and confidently defending statistical approaches and outcomes.

Support Client and Commercial teams with advanced Data Science and methodological guidance (this role goes beyond basic statistical support).

Play a leading role in the application of data and analytics strategies, ensuring solutions are analytically sound, scalable, and business‑relevant.

Innovate and design out‑of‑the‑box solutions by leveraging large, complex datasets and state‑of‑the‑art statistical and Data Science methodologies.

Collaborate closely with in‑house Data Science teams, raising analytical standards, guiding problem‑solving approaches, and aligning on priorities.

Enable Data Science technology solutions on the ground and ensure outputs meet both client expectations and internal quality standards.

Work closely with Product Enhancement, Product, and Technology teams to bring analytical solutions to market, from concept through deployment.

Experience

Degree in Mathematics, Statistics, Data Science, or a related quantitative field involving deep statistical analysis of large datasets.

5+ years of hands‑on experience in market research, consumer analytics, or a relevant Data Science field (strong preference for candidates operating beyond junior or execution‑only roles).

Demonstrated ability to independently own complex analytical problems, including methodology selection, statistical reasoning, and interpretation.

Solid understanding of the CPG/FMCG industry and retail market dynamics, and how analytics drives measurable client impact.

Proven experience working in client‑facing, high‑pressure environments, handling challenging questions, escalations, and tight timelines.

Excellent problem‑solving, deductive reasoning, and analytical thinking skills.
