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. #J-18808-Ljbffr
