Sydney | Melbourne | Brisbane | Hybrid Work Model | Competitive base + super + benefits
Most cyber security analyst roles keep you working one platform's alert queue and hand the detection work to someone else. This one puts you across Microsoft Sentinel, SentinelOne and Splunk, on customer environments that are never the same twice, and gives you a real hand in writing and tuning the detections you triage. As a Cyber Security Analyst in our cyber security team, you'll investigate and respond to security events for some of Australia's biggest brands while building the detection content that keeps them protected. If you are ready to take on more, not just more of the same, this is the role.

What You'll Be Doing
You'll join our cyber security team, working across daily operations, detection and continuous improvement for a broad customer base. Your week moves between triaging and resolving live events and improving the detections that catch the next one, whether that is writing a new rule, tuning a noisy one or tracing a coverage gap back to a missing log source. You'll work closely with fellow analysts, threat hunters and customer stakeholders, both remotely and onsite. There is real scope here to shape how we detect, not just how we respond.
Investigate SIEM events and own incident response from triage through escalation to resolution
Analyse phishing activity, suspicious domains and IP addresses to identify genuine risk quickly
Author reliable detections for defined behaviours across Microsoft Sentinel, SentinelOne and Splunk, applying thresholds, aggregation and suppression
Tune routine rules to cut false positives without losing true positives, and document the rationale
Build detections aimed at each customer's stated risks and most critical assets, and explain the why behind a rule in business terms
Audit customer logging against intended coverage and flag concrete gaps with the impact of each
What You'll Bring
The Essentials
3 or more years in an enterprise scale security operations environment, including hands on incident response
Hands on experience with modern detection and response tooling, including SIEM, XDR and EDR
Experience writing or tuning detection rules in Microsoft Sentinel, SentinelOne or Splunk, using their query languages
Solid grounding in Microsoft security technologies, with confidence working across Linux or Unix environments
Working knowledge of MITRE ATT&CK, NIST and ISO 27000, and the ability to explain technical detail to technical and non technical audiences
Bonus Points
Current certifications such as SC 200, Blue Team Level 1 or 2, SANS Incident Responder or GIAC GCDA
Broad understanding of cloud, networking and firewall technologies
Experience with vulnerability management tooling such as Rapid7, Tenable or Qualys
Even if you don't tick every box, don't let that hold you back. If this sounds like your kind of challenge, we'd genuinely love to hear from you.
