AI Malware Classification Researcher

Eliana Magnusson

Full-time · Job · London

About the role

Traditional signature-based malware detection catches what it's seen before. Our system catches what it hasn't. We use deep learning to classify malware families from behavioral traces — API call sequences, network patterns, file system mutations — processing 12 million samples per week across our threat intelligence pipeline. The challenge isn't training a model that works on last month's data. It's building a system that stays accurate as adversaries evolve. You'll design models with built-in concept drift detection, develop adversarial robustness testing, and build the feedback loop that retrains on newly confirmed threats within hours, not weeks. We publish research and encourage conference submissions. Your last two years should include at least one published paper or significant open-source contribution in ML or security. You'll join a research team of four, reporting to our CTO, with direct access to one of the largest proprietary malware datasets in the industry.

Responsibilities

  • Design deep learning models for behavioral malware classification
  • Build concept drift detection systems to maintain model accuracy over time
  • Develop adversarial robustness testing frameworks for security models
  • Implement automated retraining pipelines triggered by new threat data
  • Publish research findings internally and at security conferences
  • Evaluate emerging ML techniques for applicability to threat detection

Requirements

  • 6+ years in ML research or engineering with publications
  • Experience with sequence modeling or behavioral analysis
  • Strong PyTorch skills and familiarity with experiment tracking
  • Understanding of cybersecurity concepts and threat landscapes
  • Track record of shipping ML systems that handle adversarial inputs

Benefits

  • Fully remote across European or US time zones
  • Research conference budget with no cap
  • 30 days PTO
  • Equity participation
  • Sabbatical program after 3 years
