Machine Learning Engineer
Remote, Europe | (UK, Germany, Spain)
About the role
A growth-stage cybersecurity company is hiring a Machine Learning Engineer to embed AI capabilities into its Web Application Firewall and bot mitigation product. You'll work directly with the Head of AI, using live web traffic data to build models that detect malicious traffic, bots and anomalies.
There's no data engineering function in place yet, so a large part of the role is your own data cleaning and feature engineering before you get to modelling. The brief prioritises a proactive, research-driven mindset over a fixed technical stack.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
