Senior Cyber Security Engineer - Blue Team

About the role

Teneo seeks a skilled and self-sufficient Cybersecurity Engineer to join our security team in Sydney or Melbourne. In this role you will focus primarily on detection engineering and blue-team operations: designing, writing and tuning detection / SIEM / XDR rules, responding to security alerts and incidents, and maintaining our security posture across cloud, network and endpoint environments. You will play a critical role in strengthening our defences, automating security processes, and enabling IT and business teams to operate securely. The position is based in Melbourne and follows a hybrid working model, with three days per week in the office.

Responsibilities

• Design, develop, and maintain detection logic and rules (SIEM / XDR / log-management) to identify suspected malicious activity, anomalies, or policy violations across network, cloud, endpoint, and identity systems.
• Configure, deploy, and manage security tooling: SIEM / XDR platforms, log management, IDS/IPS/NDR, firewalls, endpoint protection, cloud-security tools, and other security infrastructure.
• Triage and investigate alerts: perform log analysis, correlate events, determine real threats, escalate or respond as needed.
• Perform vulnerability assessments, threat hunting, risk-based tuning of detection rules, and threat modelling for identified CVEs / weaknesses.
• Participate in incident response: containment, mitigation, root-cause analysis, remediation, documentation, lessons-learned, and improvement of detection strategies.
• Automate security operations where possible: develop scripts or workflows (e.g., via Python, PowerShell, Bash, SOAR integrations) to streamline monitoring, alerting, incident handling, and reporting.
• Collaborate with IT, DevOps, and business stakeholders to embed security best practices into system and network architecture, cloud infrastructure, and software deployments.
• Maintain and enforce security policies, standards, access controls, and compliance frameworks (e.g., relevant regulatory or industry standards).
• Produce clear documentation, dashboards, reports, and run-books for detection logic, incidents, and ongoing security operations.

Requirements

• Several years (e.g., 5-7+) of professional experience in cybersecurity engineering / operations, with hands-on experience in detection, SIEM/XDR, log management, incident response, and security tool administration.
• Strong technical knowledge in network security, cloud security (e.g., AWS, Azure, or similar), endpoint security, identity and access management (IAM), firewall/IDS/IPS, and intrusion detection/prevention.
• Proven ability to author, tune and review detection rules / alerts / log-parsing logic, and to perform advanced log analysis and event correlation.
• Familiarity with scripting or automation (e.g., Python, PowerShell, Bash), for building detection logic, automating response, or managing security tool configurations.
• Solid understanding of security frameworks, best practices, and threat-detection methodologies.
• Strong analytical, problem-solving, communication, and collaboration skills - able to work independently but also engage with IT/security stakeholders.
• Desirable
• Experience with cloud-native security environments and multi-cloud deployments.
• Familiarity with SOAR or security automation/orchestration platforms.
• Certifications such as CISSP, CISM, CEH, or other relevant credentials.
• Prior experience in a blue team / SOC / detection engineering / incident response role.
• Understanding of compliance, regulatory standards, and risk management best practices.
