Council of the City of Sydney, Australia Lifebyte Systems Full time

We are seeking a highly skilled Security Engineer to design, build and optimise our security platform and controls across on‑prem and cloud. Partnering with SOC/incident response, IT/DevOps and business teams, you will strengthen SIEM analytics, EDR policy and response, identity and access (IAM) controls, and security logging/retention to accelerate detection, containment and risk‑based decision making. (This role includes core traditional security engineer responsibilities.)

Key Responsibilities

Endpoint & Detection Operations

- Operate and fine-tune EDR, ensuring high visibility and timely response to detections.

- Investigate alerts, triage incidents, and coordinate remediation with IT and engineering teams.

- Develop and maintain detection rules, response playbooks, and operational dashboards.

Vulnerability & Exposure Management

- Run regular vulnerability scans across endpoints, servers, and cloud workloads.

- Prioritise findings based on exploitability and asset criticality.

- Work with system owners to track remediation progress and verify fixes.

Cloud Security (AWS Focus)

- Review and improve AWS configurations using AWS tools or CNAPP / CSPM monitoring tools (e.g., Wiz, Orca)

- Support secure architecture and IaC practices (Terraform, CloudFormation) with dev teams.

- Automate checks and alerting for misconfigurations and policy violations.

Secure Development & DevSecOps (Nice to Have)

- Support developers on secure coding practices and pipeline integration (e.g., Snyk).

- Review secrets management, API credential handling, and CI/CD pipeline security.

Identity & Access Control

- Implement and maintain least privilege and MFA policies across systems.

- Assist with SSO/SCIM integrations (e.g., Entra ID, 1Password, Cloudflare Zero Trust).

Collaboration & Continuous Improvement

- Work alongside IT Operations and Cloud teams to deploy, harden, and monitor security tools.

- Participate in incident response exercises, phishing simulations, and post-incident reviews.

- Contribute to process documentation and internal knowledge base (e.g., runbooks, playbooks).

- 4–6 years of hands‑on security experience, ideally in endpoint protection, cloud security, or vulnerability management.

- Strong working knowledge of AWS security services, IAM, and network fundamentals.

- Practical experience with EDR tools (CrowdStrike, Defender, etc.) and vulnerability scanners (Qualys, Tenable, etc.).

- Solid understanding of incident response, detection engineering, and access control principles.

- Exposure to security frameworks (ISO 27001, SOC 2, NIST) is a plus, but not mandatory.

- Clear communicator who can explain security findings to both technical and non-technical teams.

- Hybrid working arrangement - 2 Days of remote work per week

- Opportunities for enriching career growth, including exposure to regional contexts

- Complimentary snacks and beverages available in the office pantry

- Healthcare coverage (medical, dental, optical), gym benefits

- Flexibility in smart casual dress code

- Young, vibrant and open work culture
