Security Engineer, AWS Security

About the Role Amazon Web Services (AWS) is the leading cloud service provider, delivering virtualised infrastructure, storage, networking, messaging, and many other services worldwide. AWS runs a globally distributed environment, operating at massive levels of scale. Businesses, from start‑ups to enterprises to large government customers, run their operations and applications on AWS’s highly secure infrastructure. AWS Security is looking for a Security Systems Engineer to play a pivotal role in ensuring the security and integrity of our systems and infrastructure. You will work closely with our security team to implement and maintain robust security measures that adhere to Australian Government security requirements, including the Protective Security Policy Framework (PSPF) and the Information Security Manual (ISM). Key Responsibilities Perform security event monitoring, incident management and response. Develop, tune, and maintain SIEM detections, dashboards, and correlation rules. Conduct proactive threat hunting and analysis to identify suspicious behaviour. Investigate, respond and be the escalation point for security alerts and incidents. Support the integration and optimisation of security data sources within SIEM platforms. Contribute to continuous improvement of SOC processes and automation initiatives including authoring SOC SOPs and runbooks. Apply frameworks such as MITRE ATT&CK and NIST in concert with the ISM and PSPF to guide security operations. Perform on‑call duties as required, out of business hours. A Day in the Life Responding to new detections: Monitor security alerts in real‑time, investigate suspicious activities by analysing logs and network traffic, determine if incidents are legitimate threats or false positives, and coordinate immediate response actions including containment and remediation when threats are confirmed. Write security detections: Develop and implement custom detection rules based on emerging threat intelligence, tune existing security signatures to reduce false positives while maintaining coverage, and create automated alerts for specific attack patterns or indicators of compromise relevant to the organization’s environment. Threat hunt: Proactively search through network logs, endpoint data, and system activities for signs of advanced persistent threats that may have evaded automated detection systems, using threat intelligence feeds and behavioural analysis to identify potential security breaches before they cause significant damage. Work with service teams on security issues: Collaborate with IT, network, and application teams to remediate identified vulnerabilities, coordinate security patches and system hardening efforts, provide security guidance during incident response, and ensure proper implementation of security controls across all infrastructure components. Generate metrics and dashboards: Create and maintain security performance indicators including incident response times, threat detection rates, and system availability metrics, develop executive‑level reports summarizing security posture and trends, and build real‑time dashboards for continuous monitoring of security operations effectiveness.
