You’ll work in a secure VDI environment and must be comfortable navigating complex and sensitive data.

Key responsibilities include:

  • Ingesting and transforming large datasets (100M+ rows), from Oracle, SQL Server, and flat files (CSV, XML).

  • Writing and reviewing SQL and Python (Pandas) scripts to clean and join data across multiple sources.

  • Conducting forensic comparisons between data sources (e.g., matching millions of XML records to transactional logs).

  • Supporting peer code reviews to ensure high quality and reduce rework.

  • Collaborating with data consultants and forensic analysts to troubleshoot logic and ensure audit-quality outputs.


KEY SKILLS & REQUIREMENTS

  • Strong SQL (T-SQL, Oracle, or PostgreSQL) – must be comfortable with complex joins and large volumes

  • Python with Pandas – mandatory for data transformation and wrangling

  • Experience working with large operational databases, text files, and legacy data sources

  • Strong attention to detail and a forensic mindset – ability to spot inconsistencies, gaps, and unusual data behaviour

  • Prior experience in a regulated, sensitive, or secure data environment is a big plus

  • Previous work in or alongside large consultancy firms
