This role requires someone who can hit the ground running, operate autonomously, and communicate effectively with senior stakeholders.

* Apply strong problem-solving and critical-thinking skills to uncover insights and guide decision-making.
* Work cross-functionally to ensure data science outputs are actionable, practical, and aligned with business priorities.
Required Skills:
* 6+ years of experience in Data Science or related analytical roles.
* Deep expertise in experimentation, including advanced techniques and real-world constraints (e.g., no randomisation, low-power scenarios).
* Proficient in Python or R, with strong hands-on experience in statistical modelling and experimentation frameworks.
* Working knowledge of SQL for data extraction and manipulation.
* Exceptional communication skills, with the ability to engage senior non-technical stakeholders.
