incident response by acting as the second-line triage point for escalated issues, resolving complex tickets, and routing unresolved infrastructure bottlenecks to the right engineering squads.\nExecute operations and deployments by performing system configuration changes, validating environment health, and collaborating with technology teams to push new products live under strict change controls.\nLead major incident triage by conducting deep-dive investigations and root-cause analysis during outages, coordinating cross-team efforts to deliver clear workarounds and long-term fixes.\nDrive continuous reliability by identifying manual overhead or performance bottlenecks, contributing directly to infrastructure automation, and partnering with development squads to build system resilience.\nOwn operational knowledge management by authoring comprehensive Standard Operating Procedures (SOPs) and maintaining clear runbooks to elevate collective team capacity.\nTo be successful you will be able to demonstrate the following:\nAustralian Citizenship: Must hold or have the ability to obtain and maintain an Australian Government Security Clearance.\n3 to 5 years of operational experience in SecOps, network administration, or technical support within complex IT, cloud, or highly regulated enterprise environments.\nAdvanced problem-solving and sharp attention to detail, with a proven ability to think critically during high-pressure network and security incidents.\nStrong adaptability and stakeholder communication skills, comfortably managing incident communications and translating technical findings into clear risk updates.\nFamiliarity with structured frameworks such as ITIL, Agile delivery methods, or secure governance models, with a focus on automation and continuous compliance.\nSecurity Monitoring & Triage: Practical experience identifying anomalous network behavior, auditing firewall rule bases, and managing security alerts within a SOC or high-compliance operations environment.\nVulnerability & Compliance Management: Competency validating environment configurations against strict compliance benchmarks, ensuring secure patch management, and eliminating configuration drift.\nIncident Response Runbooks: Proven ability to follow and enhance structured incident playbooks for quick isolation, mitigation, and post-incident compliance logging.\nRelevant Security Certifications: Holding CompTIA Security+, CEH, GIAC, or equivalent security-focused credentials alongside practical Linux CLI and automation scripting (Python/Shell) experience is highly desirable.\nThe grit and professional maturity required to navigate a fast-paced, expanding scale-up environment where rapid execution and practical problem-solving are paramount.\nWhat’s in it for you?\nBe at the forefront of cyberwarfare, the greatest technology challenge of our generation\nUp to 10% of time dedicated to learning & development\n5 days of wellness leave per year\nCompany paid parental leave\nA diverse culture where we celebrate our people and their unique, individual perspectives\nOur culture is a big part of who we are so, for us, it
