Our technology stack is built on modern open-source components, both enabling day-to-day research and development, and supporting our 24hr trading. \nWith adoption of AI-agents we are investing in security as a first-class concern. Man has a sophisticated AI platform - MAIA - that offers the best foundation models on our modern technology stack. As agents become more powerful, the security platform which supports safe agentic workflows is critical. \nThis senior role will own the security architecture from end-to-end, setting the technical direction for the security platform. This is a hands-on leadership role. You will set direction, make and document key design decisions and stay close to the engineering, building prototypes and reviewing code alongside the engineers who deliver it. \n\nRole Responsibilities\nArchitecture and Direction \nDefine and own the target security architecture (components, services and APIs) for internal applications and platforms, covering identity, authorisation and secrets. \nSet the Zero Trust roadmap: user and machine identity, just-in-time and least-privilege access, and policy enforcement at the point of use. \nMake and record architectural decisions, balancing risk, delivery speed and operating cost. \nPublish reference designs and paved-path patterns so that the default for teams is also the secure one. \nEngineering Leadership \nLead the design of the security policy engine for scoped time-bound system and data access. \nDesign and build the platform APIs that applications, AI agents and users call. \nMentor engineers and lead design reviews. \nCollaboration \nWork with IAM, Infosec, Security Operations and Infrastructure teams so that controls can be monitored, detected and audited. \nWorking with Developer, Infrastructure and AI platform teams to ensure solutions balance the security and agility requirements of Man. \nExplain risk clearly to engineers, senior leadership and non-technical stakeholders, and support audit and regulatory work. \n\nKey Competencies\nRequired \nSignificant experience in security engineering or architecture, including end-to-end ownership of security architecture for production platforms. \nStrong Python skills; comfortable with Bash, SQL and log query languages. \nPolicy-as-code (e.g., OPA/Rego, Kyverno, Cedar, OpenFGA, SPIFFE/SPIRE). \nInfrastructure-as-code and GitOps (Terraform, Ansible, Helm). \nDeep understanding of authentication, authorisation and secrets management (OIDC/OAuth, Azure AD/Entra ID, vault, Keycloak) and of access control models. \nDesirable \nSecurity of AI agents and LLM applications (delegated access, tool-use authorisation, prompt injection). \nHands-on experience with Kubernetes, Linux and containerised environments, including network policies. \nStrong grasp of network security controls: firewalls, WAFs, segmentation, TLS termination and egress filtering. \nA structured approach to threat modelling and risk assessment, and the ability to explain risk clearly to any audience. \nExperience in financial services or another regulated environment. \nInclusion, Work-Life Balance and Benefits at Man Group\nYou'll thrive in our working environment that champions equality of opportunity.
