  • Lead data reconciliation and validation of migrated datasets
  • Develop and optimise ETL processes within controlled production environments
  • Ensure production safety, minimising risk to BAU payment processing

Core Technical Skills

  • Strong expertise in IBM DB2 on Mainframe, including:

    • Managing data lineage and traceability

Required Experience

  • Hands-on delivery of data migration in banking, ideally within payments systems or other mission-critical transaction platforms

Preferred Experience

  • Strong familiarity with retail banking payments systems and data structures
  • Exposure to Oracle databases for adjacent extraction requirements
  • Background in capital markets or trading systems with similar high-volume, high-risk data handling

Personal Attributes

  • Comfortable working with incomplete information
  • Strong communication skills with a focus on early risk escalation

How Many Data Science Tools Do You Need to Know to Get a Data Science Job?

If you’re trying to break into data science — or progress your career — it can feel like you are drowning in names: Python, R, TensorFlow, PyTorch, SQL, Spark, AWS, Scikit-learn, Jupyter, Tableau, Power BI…the list just keeps going. With every job advert listing a different combination of tools, many applicants fall into a trap: they try to learn everything. The result? Long tool lists that sound impressive — but little depth to back them up. Here’s the straight-talk version most hiring managers won’t explicitly tell you: 👉 You don’t need to know every data science tool to get hired. 👉 You need to know the right ones — deeply — and know how to use them to solve real problems. Tools matter, but only in service of outcomes. So how many data science tools do you actually need to know to get a job? For most job seekers, the answer is not “27” — it’s more like 8–12, thoughtfully chosen and well understood. This guide explains what employers really value, which tools are core, which are role-specific, and how to focus your toolbox so your CV and interviews shine.

This guide helps you understand exactly what hiring managers look for first in data science applications — and how to structure your CV, portfolio and cover letter so you leap to the top of the shortlist.
