Job description

  • Confidence engaging senior, non-technical stakeholders and translating between technical and business needs
  • Experience working within Private Equity is highly desirable - wider Financial Services is accepted

Data Engineer - Databricks, Azure, Python, SQL - 12 Month Contract - Outside IR35 - Up to £700 p/d (dependent on experience)
