About the role

As we rapidly scale our Practice Management Software for Allied Health Professionals, ensuring the rigorous protection of sensitive healthcare data and our internal corporate environments is our highest priority. The Principal Security Engineer will serve as the premier technical authority for product, application, and internal IT security. Embracing a "builder, defender, and breaker" philosophy, this is a highly hands on role where you will execute complex cloud infrastructure security tasks, define our overarching security strategy, and drive the secure adoption of AI and data analytics. You will champion secure development practices while fostering a culture of psychological safety, balancing hands on technical execution with high level commercial advisory for the executive team.

About you

You're a hands on security leader who enjoys solving complex technical challenges while thinking strategically about business outcomes. You bring deep expertise across cloud, application and infrastructure security, with a builder's mindset and a passion for creating secure, scalable solutions. You're equally comfortable partnering with executives on commercial risk as you are working alongside engineers to strengthen security practices. Most importantly, you thrive in a fast paced scale up, collaborating across teams, adapting quickly, and leading with empathy.

• Internal IT, Data & AI Security - Define workplace IT security practices, guiding IT/ITS teams on secure operations.

• Security Architecture & Threat Modelling - Lead complex threat modelling (e.g., STRIDE) and architectural design reviews for all new platform infrastructure and SaaS features.

• Pipeline Auditing & Security Automation - Audit existing software delivery pipelines to embed automated security testing (SAST, DAST, SCA). Build custom security tooling to analyse attack surfaces and manage regression testing.

• Commercial Executive Advisory - Provide commercially aligned privacy and security guidance directly to the Executive Leadership Team (ELT/Exco), translating technical risks into business impact.

What we're looking for

• years of comprehensive experience in the Information Security industry.

• Deep hands on expertise in Cloud Infrastructure Security, specifically utilising AWS (IAM, GuardDuty) and secure data warehousing (Snowflake).

• Strong background in Application Security (AppSec) and Product Security (ProdSec) engineering, specifically within scaling tech environments.

• Extensive hands on experience conducting security assessments, complex threat modelling, security code reviews, and vulnerability assessments.

• Demonstrated experience navigating healthcare or enterprise compliance requirements (e.g., HIPAA, SOC 2, ISO 27001, Australian Privacy Principles) within a multi tenant SaaS architecture.
