Security Engineer

• Working closely with the Cyber Security team to ensure security principles are consistently applied across the engineering environment.
• Collaborating and coding with engineering teams to uplift secure development practices and reduce recurring security findings.
• Designing, building, and maintaining secure cloud and microservice solutions.
• Improving security posture through effective use of COTS products, platform controls, and network infrastructure.
• Vulnerability and Threat Management — monitoring and assessing assets including cloud infrastructure, containers, packages, APIs, and requests, with a focus on remediation and measurable risk reduction.
• Supporting the secure design and operation of AI-enabled systems, including LLM integrations, automation agents, and MCP-based architectures.
• Implementing and reviewing AI security guardrails such as access controls, data protection, prompt-injection mitigation, and output validation.
• Collaborating with cross-functional teams including engineering, operations, compliance, data, and AI platform teams.
• Contributing as an individual contributor within a cross-functional DevOps / SecOps team.
• Build or integrate services to improve security and compliance

The ideal candidate is passionate about promoting a security-first culture and has a strong, current understanding of security best practices, with particular focus on cloud security, secure design, incident handling, and operational resilience.
Experience securing microservices in cloud environments and working with configuration-as-code is important for this role. Experience securing AI-driven systems, including LLM-powered services and internal automation, is highly regarded.
Strong communication skills are essential. We value engineers who can clearly communicate risk, trade-offs, and remediation paths, and who approach collaboration with empathy for engineering challenges.

Key Skills

• Strong understanding of networking, infrastructure, and applications from a DevOps perspective with a security focus.
• Hands-on experience implementing and maintaining security controls across cloud environments (particularly AWS) and access management solutions (e.g. Auth0).
• Experience with security logging, monitoring, and vulnerability assessment, with a demonstrated ability to drive findings down and improve baseline security standards.
• Passion for secure coding practices and identifying common implementation and operational security risks.

Desirable Experience

• AWS technologies such as CloudFormation, Terraform, IAM, WAF, Node.js and/or TypeScript.
• Docker, containerised environments, serverless architectures, and Kubernetes.
• Event-driven systems.
• Securing AI platforms, including LLM integrations, MCP implementations, AI guardrails, and automation/build agents.
