🚀 Data Engineer | AI & Cybersecurity | Up to £100,000 + Benefits | London / Hybrid


Are you a Data Engineer ready to take full ownership of building a modern data platform from the ground up?


This is a rare opportunity to join an early-stage, deep-tech company at the intersection of artificial intelligence and cybersecurity, working on technology that’s pushing the limits of how machines understand and analyse complex software systems.


You’ll be joining as the first Data Engineering hire, partnering closely with the ML and Product teams to design, build, and scale the data infrastructure that powers advanced AI models. Your work will directly enable large-scale model training, data-driven product development, and cutting-edge security research.


🔧 What You’ll Be Doing

  • Architecting and building a robust data platform from scratch
  • Managing large, complex, and often messy datasets
  • Collaborating with ML and product teams to align data requirements
  • Owning data quality, governance, and modelling standards
  • Enabling scalable ML pipelines and data-driven decision-making


💡 What We’re Looking For

  • Strong experience with Python and SQL
  • Hands-on expertise with AWS or GCP (and their data services)
  • Solid understanding of data modelling, data quality, and governance principles
  • Experience working with large-scale data systems
  • A self-starter mindset with the ability to work independently and solve complex problems
  • Experience working within a start-up environment


Nice to have:

  • Experience with modern data warehouses (e.g. Snowflake, BigQuery)
  • Exposure to vector databases (e.g. Qdrant)
  • Understanding of data needs for ML training
  • Background or interest in cybersecurity, compiled languages (C/C++/Rust), or binary analysis


🌟 Why You’ll Love It Here

  • Build something from the ground up - huge ownership and technical freedom
  • Join a smart, curious team tackling truly unique technical challenges
  • Competitive salary (ÂŁ100,000)
  • Equity options, pension scheme, and private health insurance
  • Hybrid working – 3 days per week - central London
  • 25 days holiday + bank holidays


If you’re excited by the idea of shaping a data function in a cutting-edge AI startup and working on problems that most companies haven’t even begun to tackle, we’d love to hear from you.

Data Science Recruitment Trends 2025 (UK): What Job Seekers Need To Know About Today’s Hiring Process

Summary: UK data science hiring has shifted from title‑led CV screens to capability‑driven assessments that emphasise rigorous problem framing, high‑quality analytics & modelling, experiment/causality, production awareness (MLOps), governance/ethics, and measurable product or commercial impact. This guide explains what’s changed, what to expect in interviews & how to prepare—especially for product/data scientists, applied ML scientists, decision scientists, econometricians, growth/marketing analysts, and ML‑adjacent data scientists supporting LLM/AI products. Who this is for: Product/decision/data scientists, applied ML scientists, econometrics & causal inference specialists, experimentation leads, analytics engineers crossing into DS, ML generalists with strong statistics, and data scientists collaborating with platform/MLOps teams in the UK.

Why Data Science Careers in the UK Are Becoming More Multidisciplinary

Data science once meant advanced statistics, machine learning models and coding in Python or R. In the UK today, it has become one of the most in-demand professions across sectors — from healthcare to finance, retail to government. But as the field matures, employers now expect more than technical modelling skills. Modern data science is multidisciplinary. It requires not just coding and algorithms, but also legal knowledge, ethical reasoning, psychological insight, linguistic clarity and human-centred design. Data scientists are expected to interpret, communicate and apply data responsibly, with awareness of law, human behaviour and accessibility. In this article, we’ll explore why data science careers in the UK are becoming more multidisciplinary, how these five disciplines intersect with data science, and what job-seekers & employers need to know to succeed in this transformed field.

Data Science Team Structures Explained: Who Does What in a Modern Data Science Department

Data science is one of the most in-demand, dynamic, and multidisciplinary areas in the UK tech and business landscape. Organisations from finance, retail, health, government, and beyond are using data to drive decisions, automate processes, personalise services, predict trends, detect fraud, and more. To do that well, companies don’t just need good data scientists; they need teams with clearly defined roles, responsibilities, workflows, collaboration, and governance. If you're aiming for a role in data science or recruiting for one, understanding the structure of a data science department—and who does what—can make all the difference. This article breaks down the key roles, how they interact across the lifecycle of a data science project, what skills and qualifications are typical in the UK, expected salary ranges, challenges, trends, and how to build or grow an effective team.
