• 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.
• Strong knowledge of SQL for data extraction and manipulation.
• Exceptional communication skills, with the ability to engage senior non‑technical stakeholders.
• Proven ability to work autonomously, deliver impact quickly, and manage competing priorities.
• Strong analytical mindset with high attention to detail and a pragmatic approach.
• Demonstrated ability to think creatively and translate ambiguous business questions into clear analytical approaches.
• Experience coaching or leading junior team members.
