• Partner with stakeholders, architects, engineers, and suppliers to solve complex cyber security challenges within operational, budget, and capability constraints
• Maintain and evolve cyber security architecture across applications, infrastructure, and platforms across IT and OT environments, balancing innovation with resilience and risk reduction
• Provide expert input into technology and security investment decisions, helping maximise return on investment while reducing cyber and operational risk
• Champion continuous improvement in cyber security practices, standards, and ways of working, while contributing to a positive, high‑performing technical community

What Makes You a Great Fit

• Strong grounding in cyber security principles, architecture patterns, and secure‑by‑design practices
• Experience leading or contributing to solution architecture across enterprise‑scale systems and platforms
• Solid understanding of modern development and project delivery approaches, and how security is embedded across them

• A degree in Computer Science, Systems Analysis or a related field, or equivalent practical experience delivering cyber security outcomes
