Desirable to have experience or a willingness to learn in the following areas * Working in a regulated or high-security environment. * Detection engineering or incident response. * Defining security practice in a function or capability that did not previously exist. ## Description We are seeking an exceptional Staff Security Engineer to join our AI Security function. The role is expected to involve the following activities: * Design and implement security controls in the inference gateways, platforms and developer tooling used across the firm, delivered as code and configuration. * Embed controls in the systems that engineering teams already work in, so that the secure option is the default. * Define the standards and patterns other teams adopt when building with AI. * Define who an internal agent acts as, what it is permitted to reach and how those decisions are enforced. * Build telemetry that records what ran, on whose behalf and against what. * Establish how agent and automation activity is proven after the fact for audit and investigation. * Secure developer harnesses, plugins, and the dependency and model provenance they rely on. * Own secrets handling and vulnerability management across the AI tooling the firm depends on. * Set provenance and integrity requirements for models and components introduced into the firm. * Threat model live systems across platform and gateway security, agent identity and permissioning, and the AI supply chain. * Deliver the remediation resulting from threat modelling directly. * Identify gaps in control coverage and prioritise remediation against risk and delivery constraints. * Take and document control decisions in areas where no established answer exists. * Set and own the technical direction for the function's core areas and help define how the function works. * Drive the adoption of secure defaults and governed identities and gateways with a reliable audit trail. ## Related Videos - [Resilient by Design: Building Robust Architectures in High-Stakes Financial Systems](https://www.wearedevelopers.com/videos/2106-resilient-by-design-building-robust-architectures-in-high-stakes-financial-systems) - [Thinking Differently - How to Make Money from Cyber Attacks & Cheats](https://www.wearedevelopers.com/videos/745-thinking-differently-how-to-make-money-from-cyber-attacks-cheats) - [AI Pair Programming with GitHub Copilot at SAP: Looking Back, Looking Forward!](https://www.wearedevelopers.com/videos/1546-ai-pair-programming-with-github-copilot-at-sap-looking-back-looking-forward) - [Security Pitfalls for Software Engineers](https://www.wearedevelopers.com/videos/726-security-pitfalls-for-software-engineers) - [The New AI Security Stack: Observe, Detect, Protect](https://www.wearedevelopers.com/videos/100302-the-new-ai-security-stack-observe-detect-protect) - [No Keys for the Robot: GitOps as the Control Plane for Autonomous Agents](https://www.wearedevelopers.com/videos/100095-no-keys-for-the-robot-gitops-as-the-control-plane-for-autonomous-agents) ## Related Articles - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london)
