The Team
This is an outstanding opportunity to join Man Group's Security Engineering team within Technology. Man Group's business is powered by sophisticated technology, with AI accelerating the next generation of transformation. Our technology stack is built on modern open-source components, both enabling day-to-day research and development and supporting our 24-hour trading.
With the 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 that supports safe agentic workflows is critical.
We are seeking a Senior Security Engineer to build and run the components that put these principles into practice: a policy engine and APIs that allow applications, AI agents and users to authenticate, with authorisation supported by scoped, short-lived credentials. This is a hands-on engineering role, securing Man's applications and services.
Role Responsibilities
Platform Engineering
Design, build and operate security platform services and APIs such as policy decision, just-in-time access and short-lived credential issuance
Write and maintain policy-as-code that is tested, version-controlled and deployed through GitOps
Integrate the platform with identity providers (Entra/AD), secrets management (Vault) and existing internal infrastructure (Keycloak, Sailpoint)
Run services to production standards for reliability, performance and observability, including 2nd line on-call support
Enablement and Detection
Provide Python APIs and onboard application teams and AI-agent developers to the platform, with documentation that makes the secure path the easy one
Build logging, metrics and alerting for platform services, and contribute SIEM detection rules
Key Competencies
Essential
Hands-on experience building and operating production services with Python
Using Kubernetes, Linux and containerised environments, including networking fundamentals and performance troubleshooting
Solid understanding of authentication, authorisation and secrets management (OIDC/OAuth, Azure AD/Entra ID, vault technologies)

Working knowledge of observability stacks (e.g., ELK, Prometheus, Grafana), including building dashboards and alerting rules
Clear communication and a structured approach to reasoning about risk
Advantageous
Kubernetes knowledge beyond basic usage: network policies, pod security standards, admission controllers and resource quota enforcement
Policy engines and workload identity (e.g., OPA/Rego, Kyverno, Cedar, OpenFGA, SPIFFE/SPIRE, Envoy/service mesh)
API design (REST/gRPC) for internal platform consumers
