Job description

Working with a market leading systematic hedge fund.

They are hiring a Staff Security AI Engineer.

Our client is building an AI Security function focused on enabling the safe adoption of frontier AI. This is a hands-on engineering role: building security controls directly into LLM/inference gateways, AI platforms, developer tooling and agent frameworks, rather than primarily reviewing or advising on them.

The scope includes agent identity and permissions, AI supply-chain security, model/component provenance, telemetry and auditability, cloud/CI/CD security, and threat modelling. There’s also significant ownership, you’d help set the technical direction and establish security patterns in areas where established practice doesn’t yet exist.
