- Continuously refine security approaches to balance risk, usability, and performance.
3-7 years’ experience in security engineering, infrastructure security, or a related technical field.
- Strong scripting or programming capability (Python or similar), with an emphasis on automation.
- Experience managing code and configurations using version control systems.
- Solid understanding of core security concepts including threat modelling, attack vectors, and defensive controls.
- Ability to assess risk pragmatically and explain security decisions in context.
- Hands-on mindset - comfortable building tools, not just recommending solutions.
- Good personal security practices and the ability to articulate and justify them.
- (Preferred) Experience working in engineering-led environments where security is embedded rather than siloed.
