New Opportunity: Security Architect – DevSecOps & AI

We're supporting a leading global financial services organisation, who are looking for a hands-on Security Architect to secure its next‑gen technology platforms.

This role suits an engineer or solutions‑minded builder with a security mindset, not a traditional security architect. You'll work at the intersection of AI, cloud, and up-to-date engineering practice, embedding security into the fabric of how the business builds and ships software, not as a gatekeeper, but as a genuine enabler of innovation.

What you'll do

- Lead threat modelling and design security controls for agentic and Agent-to-Agent (A2A) architectures, including mitigations for prompt injection
- Build and oversee CI/CD security controls, writing automation scripts and resolving dependency issues hands‑on
- Set security architecture across AWS, GCP, and Azure, with a focus on container runtime security
- Advise technical stakeholders, translating risk into pragmatic, business‑friendly strategies

What you bring

- Hands‑on engineering or solutions experience, you can write scripts, debug pipelines,



and get into the weeds
- Practical understanding of AI security concepts like prompt injection, not just theory
- Familiarity with multi‑agent frameworks such as LangGraph and ADK
- Real experience with CI/CD platforms and Git‑based tools (GitHub Enterprise, GitLab), plus supply chain security
- Hands‑on expertise securing container runtimes across major cloud providers
- Strong communication skills and the ability to influence engineering teams
- A risk‑aware mindset that enables innovation rather than slowing it

We're especially interested in people who've come up through engineering or product‑focused roles rather than a conventional security career path, including those from smaller organisations where you've worn multiple hats. Architectural pattern‑building can be learned on the job; deep hands‑on engineering skills cannot.

If you're excited by the challenge of securing AI‑driven, cloud‑native platforms at scale, we'd love to hear from you.
