Sydney, New South Wales, 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).

Requirements

  • 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.

Benefits

  • 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
