Full description
This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for a Senior Platform Security Engineer – AI Resilience & Security Enhancements (Contract) based in Ireland.
In this hands-on contract role, you will strengthen the security and resilience of a modern engineering platform, with a particular focus on AI-enabled workflows and secure software delivery. You will work closely with platform, engineering, and security teams to design, prototype, and implement practical security controls. Your work will span secure autonomous agent execution, CI/CD security, production access management, container security, and software supply chain integrity. You will turn security requirements into reliable, maintainable tooling and workflows that developers can use in their day-to-day work. The role combines technical problem-solving, automation, and close collaboration with engineers to deliver measurable improvements to production systems. You will help improve security without compromising service availability or engineering productivity.
Accountabilities
-
Design, evaluate, and implement controls for secure autonomous AI agent execution, including policy enforcement, permissions, sandboxing, execution isolation, and auditability.
-
Integrate security checks into CI/CD pipelines and pull request workflows to identify vulnerable or unsafe code changes before they are merged.
-
Evaluate conventional security tools and AI-assisted code security approaches, assessing detection accuracy, false positives, potential bypasses, and developer usability.
-
Strengthen production access controls through least-privilege permissions, secure privileged-access pathways, session controls, and comprehensive audit trails.
-
Adapt engineering tools and workflows to support secure, controlled access to production environments.
-
Improve CI/CD and software supply chain security through secure builds, dependency and container scanning, provenance, artifact signing, software bills of materials (SBOMs), and policy enforcement.
-
Develop practical security automation and platform guardrails that engineering teams can adopt, operate, and maintain.
-
Collaborate directly with software engineers on technical design, prototyping, implementation, and the integration of security improvements into production systems.
-
Contribute to broader security engineering initiatives, partnering with specialist teams when deeper domain expertise is required.
