Senior Cyber Security Engineer

Who We Are

As a Senior Cyber Security Engineer, you'll play a pivotal role in safeguarding Entain's digital ecosystem — from on-premises networks to our growing cloud environments. You'll leverage your technical expertise, strategic thinking, and leadership to design, implement, and continuously enhance our security posture across complex systems that power millions of customer experiences every day.

You'll thrive in an environment that challenges you to think critically, balance security with agility, and collaborate across diverse teams. With your deep understanding of cyber threats, risk management, and modern cloud security, you'll help shape how Entain protects its assets, data, and customers.

This is your opportunity to lead initiatives that elevate our resilience, drive innovation, and embed security at the heart of everything we do.

Your Impact

Join Entain as a Senior Cyber Security Engineer and help define what exceptional cyber resilience looks like in the world of sports, gaming, and digital entertainment. You'll play a key role in developing and managing security systems that ensure the integrity, confidentiality, and availability of our platforms.

Working closely with Technology Leadership, Software Engineering, and SRE teams, you'll champion proactive threat detection, effective risk mitigation, and a culture of security awareness. You'll lead from the front — strengthening Entain's defences, driving automation across our tooling stack, and ensuring our operations remain compliant, scalable, and secure.

If you're driven by curiosity, precision, and purpose — and love solving complex security challenges in a high-impact environment — this role is your next big play.

A Day in the Life

Based in our vibrant Bowen Hills office (or Wellington, if you're across the ditch), you'll enjoy a flexible hybrid work model that supports both deep technical focus and collaborative teamwork. No two days are the same — one day you might be refining threat detection strategies; the next, leading incident response, hardening infrastructure, or mentoring engineers on secure design principles.

You'll work alongside passionate technologists who care deeply about customer trust, reliability, and performance — all while enjoying a culture that values balance, innovation, and connection.

What You'll Do

• Fortify Entain's digital defences by designing, implementing, and maintaining secure network, cloud, and endpoint architectures across AWS, Azure, and on-prem environments.
• Lead vulnerability and risk management — identifying, assessing, and remediating security weaknesses across systems, software, and third-party integrations.
• Embed automation and efficiency by leveraging scripting and modern security tooling (e.g., SIEM, EDR, SOAR) to detect, respond, and recover swiftly.
• Drive security monitoring and operational awareness, supporting incident response from triage to containment and recovery.
• Integrate security at every stage of development and operations, ensuring alignment with frameworks such as ACSC ISM, NIST, ISO27001, and MITRE ATT&CK.
• Collaborate across teams to ensure risk mitigation aligns with business priorities, compliance obligations, and customer expectations.
• Mentor and guide peers, providing thought leadership and fostering a culture of shared accountability for security.
• Champion proactive security awareness, helping teams adopt secure practices and stay ahead of emerging threats.

Your Strengths

• Proven experience in cyber security engineering, with hands-on technical expertise across cloud and on-premises environments.
• Strong understanding of Azure, AWS, and containerised architectures (AKS, EKS, Container Registry).
• Demonstrated experience with Infrastructure as Code (Terraform, Ansible, ARM/Bicep, CloudFormation) and CI/CD pipeline security.
• Deep knowledge of security operations, incident response, and threat management.
• Ability to communicate complex security concepts clearly to technical and non-technical stakeholders.
• Strategic thinker with a passion for automation, innovation, and continuous improvement.
• Collaborative and pragmatic — able to balance strong risk awareness with business agility.
• Committed to uplifting others, sharing knowledge, and leading by example.
