We’re working with a long-established intelligence platform hiring into a data platform engineering role focused on some genuinely complex data problems.


This is not a typical backend role and not a pure data engineering position either.


It sits across ETL pipelines, knowledge graphs, search systems and APIs within an event-driven AWS environment.


What you’ll be working on:

  • Building and optimizing data pipelines from ingestion through to delivery
  • Working with large-scale, relationship-heavy datasets (hundreds of millions of connections)
  • Supporting a knowledge graph that underlies search and data products
  • Improving how data flows into search indexes and APIs
  • Tackling performance challenges across distributed systems

Tech environment:

  • AWS
  • OpenSearch / Elasticsearch
  • Graph technologies (Neo4j-style)
  • Event-driven architecture

What they’re looking for:

  • Strong software engineering background
  • Experience working with complex data systems or data pipelines
  • Exposure to search, graph databases, or distributed systems
  • Someone who enjoys solving data problems end‑to‑end rather than specialising narrowly

Why it’s interesting:

  • Real ownership across the full data lifecycle
  • Complex graph and data modelling challenges
  • Opportunity to shape how a large-scale data platform evolves
  • Team with strong foundations but looking to raise the technical bar

Package:

  • Hybrid working (Croydon OR Manchester, 2 days per week)

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.
