Principal Security Engineer

Principal Security Engineer

Permanent | Sydney Only | Hybrid Working

Competitive salary package (negotiable) + sign-on bonus + relocation support

The Company

We’re partnering with a leading global financial services organisation with a significant technology footprint and a highly engineering-led culture.

The security function is responsible for protecting the firm’s technology platforms, operational environments, and critical data assets. The Sydney team is continuing to grow as part of a global follow-the-sun security model, working closely with international engineering and security teams.

The Role

This is a highly technical, senior, 100% hands-on individual contributor role sitting within the security platforms and infrastructure function.

This position is not focused on stakeholder management, governance, or SOC/detection & response. Instead, you’ll be responsible for owning and engineering the underlying security platforms, tooling, and configurations that support the organisation globally.

The ideal candidate will bring strong experience across network security, DLP, and identity/SSO technologies, alongside a strong engineering mindset. There is genuine autonomy in this environment, with an expectation that security enables the business rather than slows it down.

Key Responsibilities

• Manage and maintain core security platforms across network, identity, endpoint, and cloud security domains.
• Process security-related tickets and change requests, remediate vulnerabilities, administer identity controls, and tune security controls to balance protection with business usability.
• Lead firewall administration and uplift activities across Palo Alto and Fortinet environments (~60% of workload).
• Engineer and support identity platforms, with Okta as the core authentication and SSO platform.
• Implement scalable and automated operational processes across hybrid, multi-cloud, and on-premise environments.
• Troubleshoot complex issues across security tooling, integrations, and underlying infrastructure stacks.
• Participate in a global 24/7 follow-the-sun operational capability.
• Contribute to the rollout of new security controls with a focus on operability, observability, and long-term maintainability.

Experience Required

• 5-10+ years’ experience in security engineering or security platform operations.
• Strong hands-on experience across network security, identity, endpoint, and cloud security domains.
• Deep experience with network security technologies including firewalls, proxies, and SASE platforms (ideally with Palo Alto and/or Fortinet).
• Experience with Okta or equivalent IAM/SSO technologies.
• Infrastructure-as-Code (IaC) and platform engineering experience highly regarded.
• Strong troubleshooting capability across hybrid infrastructure environments.
• Programming or scripting capability for automation and operational tooling.

Why Join?

• Competitive package including base + super + sign-on bonus + performance bonus + additional allowances.
• Access to leading AI, cloud, and security tooling in a highly mature engineering environment.
• Strong technical culture that values engineering depth over consulting or presentation-heavy work.
• Minimal bureaucracy and genuine autonomy to build and improve platforms
• International onboarding and collaboration opportunities across global offices.
