Data Analyst (Data Wrangler, SQL, Python)
Location: Primarily remote (occasional collaboration days in London)
Contract: Until end December 2025 (strong possibility of extension)
Day Rate: £375-£425 (IR35, TBC)
About the Role
Join a specialist team within a leading financial services advisory consultancy, working on a high-profile, confidential investigation. This role is heavily focused on extracting, wrangling and preparing extremely large datasets to support complex forensic analysis and reporting.

-
Conduct thorough quality checks, spotting inconsistencies or issues proactively.

Consultancy experience is absolutely critical – candidates must come from a Big Four or equivalent consultancy environment. This ensures the ability to operate in fast-paced, multi-stakeholder projects, with a rigorous approach to quality and delivery.
-
A forensic, investigative mindset is equally essential. This work involves dissecting sensitive datasets to identify discrepancies and support complex conclusions, far beyond typical data analyst or BI dashboard work.

Key Requirements
-
3-5 years’ data-focused experience in professional services or consulting environments.
