Senior AI Security Engineer
London – Hybrid
The client:
This company uses AI to change how new medicines are discovered. Their platform runs on autonomous AI agents, right at the edge of what's currently possible, and they need security to keep pace with that speed.
Reporting straight into the CISO. Think of yourself as the bridge between ML engineering, platform architecture, and security, making sure nothing sensitive gets exposed as the science moves fast.
It’s still a scaling environment. There’s ambiguity, and you’ll be expected to take ownership and shape how security is designed and implemented across the business.
The role:
As Senior AI Security Engineer, you'll take ownership of security across the AI platform and its agentic systems.
- Map out the threats specific to AI and ML, and build that into a proper risk framework
- Decide how model weights, training data, and code get tracked and locked down
- Build guardrails and sandboxing for LLMs and autonomous agents, with real-time monitoring behind it
- Work closely with ML researchers and engineers, embedding security across the whole ML lifecycle
- Lead the response when something goes wrong, using ML techniques to catch what standard tools miss
- Help turn emerging AI regulation into something the business can actually keep up with
- Partner with Legal and Compliance to shape what responsible AI security looks like in practice
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.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
About you (skills/experience):
You will bring:
- A genuine understanding of deep learning (JAX, PyTorch, or TensorFlow), and you've worked with large-scale cloud training or inference infrastructure
- Think like an attacker on AI systems: prompt injection, model inversion, and data poisoning are all familiar, and you know the OWASP Top 10 for LLMs and MITRE ATLAS
- Proven experience in securing agentic systems before, and understand identity and access controls between agents
- Comfortable in cloud security, GCP ideally, with solid container and multi-cloud experience
- Can write production-grade code, Python preferred, so you build your own tooling
- Communicate well, sit comfortably with ambiguity, and can turn ML risk into something engineers can act on
