This is a newly created role for a hands-on security engineer that has a true builder's mindset. We're looking for someone who enjoys solving complex problems through automation, improving security at scale and embedding security into modern engineering environments.
You'll be defining, building and scaling a Security Engineering and Operations function from scratch, lifting and shifting what doesn't work and identifying innovative ways to optimise workflows. This is particularly well suited for those who thrive in Detection Engineering and have experience in security automation, Google Cloud Platform infrastructure, DevSecOps, log ingestion, detection engineering, and securing AI-driven applications within modern cloud environments.
Key Responsibilities:- Designing and building security automation across vulnerability triage, sandboxing, remediation workflows, and auto-patching.
- Securing cloud infrastructure with a strong focus on Google Cloud Platform, Amazon Web Services, and infrastructure-as-code using Terraform.
- Supporting security architecture and security operations, with particular focus on ingesting and analysing logs from SaaS platforms, cloud environments, and ideally some Microsoft ecosystems.
- Embedding security controls into CI/CD pipelines and broader engineering workflows to strengthen DevSecOps maturity.
- Contributing to security initiatives across AI systems, including securing LLM applications, agent-based workflows, and automated threat modelling.
- Experience building practical security automation rather than relying solely on manual processes.
- Strong cloud security knowledge, particularly in Google Cloud Platform, with solid understanding of IaC principles.
- Exposure to modern application security, threat modelling, and engineering-led security practices.
- Interest or experience in AI/LLM security, including securing agentic or automated application environments.
- Basic to intermediate scripting capability in Python and solid working knowledge of Linux.
