• Work alongside other embedded architects and the client's security leadership
• Join a practice that grows senior architects into lead roles

What you'll need to succeed

• A solid 10 years in security, with senior architecture experience
• Real depth in at least one of AWS, Azure or GCP
• Client‑facing experience, with the judgement to push back and hold your position
• Design and ability to make decisions you can explain and defend under questioning
• Experience governing third‑party delivery is highly regarded
• Full, unrestricted right to work in Australia mandatory as a PR or Citizen
