The ideal candidate will have the following skills:

• Experience conducting security assessments, code reviews, and vulnerability management across diverse technology stacks
• Experience in building full-stack products (web applications, APIs, CI tooling or low-level software)
• Hands-on experience with cloud technologies (AWS, GCP, Azure) and containers (Docker, Kubernetes), with a focus on security
• Familiarity with infrastructure-as-code (Terraform, Pulumi, CloudFormation)
• Knowledge of supply chain security risks and mitigation strategies in the SDLC
• Ability to build and automate security tools, processes, and controls (e.g., web apps, APIs, CI/CD integrations)
• Strong communication skills for advising and educating engineers on secure coding and remediation
• Knowledge of common algorithms and data structures for dealing with large quantities of data (e.g., building data-intensive systems)
• Experience analysing large datasets for security monitoring, detection, or incident response
• As part of this role, you will get exposure to all parts of the business that build software using a wide array of technologies (low-level C++ to high-level TypeScript web apps to new cloud technologies). This is the ideal role for a polyglot technologist looking to making a large impact on securing software in the group.
