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 (£100,000)
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.
