Summary: As a Security Solutions Engineer, you will serve as Lindentech’s senior technical security authority — a hands-on leader who architects, implements, and matures security frameworks across our client base. Based in West Perth, you will report directly to the CyberOperations Manager and own the delivery of Essential Eight, SMB1001, NIST, and ISO 27001 uplift programmes. You will serve as the final escalation point for incidents surfaced through our Huntress SOC partnership and play a foundational role in building and mentoring Lindentech’s security team. Your expertise will be crucial in designing maturity uplift roadmaps, translating controls into real-world deployments, and enhancing the overall security posture of diverse SME environments. Responsibilities: Own the design, implementation, and continuous improvement of security controls aligned to Essential Eight (ML2–ML3), SMB1001, NIST CSF/800-53, ISO 27001, ISM, and PSPF — tailored to each client’s risk profile and business context. Define and maintain security architecture standards across multi-tenant environments, including baseline hardening, identity and access management, endpoint protection, and network segmentation. Serve as the senior escalation point for security incidents detected by Huntress SOC and internal tooling; lead root-cause analysis, containment, eradication, and recovery. Guide, mentor, and develop junior and mid-level security engineers; define skill development pathways and foster a culture of accountability and continuous learning. Lead client security posture reviews, present framework maturity assessments, and deliver roadmap recommendations to executive and technical stakeholders. Own and optimise the security tooling stack (SIEM, EDR/XDR, IAM, email security, vulnerability management) and drive automation via PowerShell, Python, or SOAR platforms. Lead vulnerability management programmes — CVE analysis, risk-based prioritisation, remediation orchestration, and exception management. Design, implement, and maintain cybersecurity policies, standards, and procedures for both Lindentech and clients; support audit preparation and compliance reporting. Participate in after-hours on-call escalation rotations as the senior responder. Qualifications: 5–8 years’ hands-on experience in cybersecurity engineering, architecture, or operations (MSP/MSSP experience highly regarded). Bachelor’s degree in Cybersecurity, Information Security, IT, or a related field (or equivalent experience). Expert-level knowledge of Essential Eight (ML1–ML3), SMB1001, NIST CSF/800-53, ISO 27001/27002, Australian ISM, and PSPF. Proficiency in security platforms including EDR/XDR (Huntress, Defender for Endpoint), SIEM (Sentinel, Splunk), SOAR, email security, and DLP. Strong skills in identity and access management (Entra ID, Conditional Access, MFA, RBAC, PAM, FIDO2/Passwordless). Deep understanding of Microsoft 365 security, Intune, Azure security services, and Secure Score optimisation. Experience with firewalls (Fortinet, Cisco, Unifi), VPN/SSL, IDS/IPS, and DNS security. Strong PowerShell and/or Python scripting skills; familiarity with IaC tools (Terraform, Ansible) is a plus. Two or more certifications such as CISSP, CISM, Microsoft SC-200/SC-300/SC-400/AZ-500, ISO 27001 Lead Implementer/Auditor, CompTIA CASP/Security, or OSCP. Demonstrated ability to lead client engagements, present to boards/executives, and mentor technical staff.
