The opportunity

We are looking for a deeply technical Cyber Security Engineering Lead to sit at the frontline of AC3's Cyber Security Operations Centre and lead the engineering capability behind our managed security services.

This is a technical leadership role first. You do not need to have held a formal people-leader title before. You may be an experienced Level 3 engineer or lead engineer who is already the person others turn to for difficult problems, implementation decisions, quality assurance and technical guidance.

AC3 can mentor the right person through the formal people-leadership component.

What cannot be taught quickly is the technical depth: you will need strong hands-on security engineering capability, prior MSP or MSSP experience, and a track record of leading customer implementation and deployment projects as the senior or lead engineer.

What you will be doing

• Act as the senior Level 3 escalation point for complex engineering issues across AC3's managed security platform estate.
• Design, implement, deploy, configure and enhance security platforms for new and existing customers
• Lead technical delivery across customer onboarding, implementation, migration, upgrade and deployment projects from discovery through to operational handover
• Troubleshoot and resolve complex issues across security technologies such as Microsoft Sentinel, Splunk, Carbon Black, Zscaler, Rapid7, Microsoft Defender, Azure and AWS
• Produce high-quality technical artefacts including high-level and low-level designs, as-built documentation, configuration records, runbooks, procedures and support handover material.
• Own technical quality across engineering work, including peer review, implementation standards and readiness for transition into managed operations.
• Drive patching, vulnerability management and lifecycle uplift across managed security platforms in line with policy and customer SLAs.
• Lead the onboarding of new security services and work closely with customers, the SOC Manager, analysts, engineers and internal stakeholders to keep delivery moving.
• Create and maintain SOPs and runbooks used by analysts and engineers for operational support and incident response.
• Identify opportunities for automation, platform improvement and stronger repeatable engineering practices across the CSOC.
• Train, coach and technically mentor junior engineers, helping them build troubleshooting, implementation and customer-facing capability.
• Support work planning, technical prioritisation and team leadership activities, with mentoring available as you grow into any formal people-management responsibilities.

What you will bring

• Strong Level 3 cyber security engineering experience across enterprise or managed customer environments.
• Previous experience working for an MSP, MSSP, systems integrator or consultancy supporting multiple customers - this is essential.
• Demonstrated experience leading security implementation and deployment projects as the senior or lead engineer, including planning, design, build, testing, customer engagement and handover.
• Hands-on experience implementing and supporting security products used by a SOC or managed security service.
• Broad technical capability across several technologies such as Microsoft Sentinel, Splunk, Carbon Black, Zscaler, Rapid7, Microsoft Defender, Azure and AWS.
• Strong understanding of systems, infrastructure, SaaS, networks, private cloud, public cloud and the dependencies that underpin modern security environments.
• The ability to investigate difficult technical issues, establish root cause, assess risk and drive practical resolution under pressure.
• Strong knowledge of vulnerability management, security platform patching and operational lifecycle management.
• Experience producing detailed high-level and low-level designs and implementation documentation for enterprise environments.
• A customer-focused communication style and the confidence to lead technical discussions with engineers, project teams and customer stakeholders.
• The ability and willingness to train, coach and raise the technical capability of less experienced engineers.
• Australian citizenship and the ability to obtain and maintain an Australian Government security clearance at Baseline level or above. People leadership experience is not the gate
•
