JOB TITLE: Lead Data Scientist
About this Role
Why it matters:
We're advancing digital transformation within the Chief Security Office (CSO), focusing on protecting customers, colleagues, and assets from cyber threats. As a Lead Data Scientist within the Security Data and AI Lab, you will own the future of ML-driven cybersecurity—building approaches that detect, mitigate, and prevent threats while maintaining high levels of explainability and operational safety.
Why you’ll thrive:
- You specialise in cybersecurity, data science, or analytics-driven solutions.
- You are eager to work at the intersection of AI, ethical governance, and threat prevention.
- You want to innovate while balancing technology and real-world risk considerations.
What you’ll do...
You’ll lead and shape state-of-the-art data science and AI initiatives, ensuring cybersecurity solutions are scalable, ethical, and aligned with regulatory standards:
- Own the delivery of security outcomes, including defining and evolving anomaly detection models that balance performance, explainability, and operational risk.
- Lead a team of Data Scientists to:
- Drive innovation in LLM-based security automation, including:
- Prompt engineering
- Retrieval-Augmented Generation (RAG) pipelines
- Fine-tuning security-focused generative AI models
- Collaborate with Data Engineers to deliver scalable, secure, and production-ready ML pipelines on Google Cloud Platform (GCP).
- Drive innovation in LLM-based security automation, including:
- Partner with cyber defence, risk, and compliance teams to ensure custom-built models are:
- Ethical and explainable

You’ll be well-equipped if you have:
✔ Cybersecurity, fraud, or behavioural analytics experience in leading data science projects—hands-on ownership of end-to-end machine learning workflows. ✔ Technical expertise in:
- Core languages: Python
- ML frameworks: TensorFlow, PyTorch
- Cloud platforms: GCP (Google Cloud Platform)
✔ Deep domain knowledge in:
- Anomaly detection (computer vision, NLP, time-series forecasting)
- Contemporary deep-learning architectures
- Models & pipelines in production environments (upcoming focus on LLMs and generative AI is highly desirable).
✔ A strong commitment to AI ethics, model governance, and secure ML operations. ✔ Excellent communication and stakeholder management skills to bridge technical insights with business decision-making.
