Senior Security Engineer – Investigations

Join the team redefining how the world experiences design. Our flagship Sydney campus is uniquely Canva - an extension of our Surry Hills neighbourhood. It’s a thoughtfully designed space with plenty of room to collaborate, focus, and connect. This role is based in Sydney, and we’re looking for someone who calls it home. Our hybrid way of working gives you the flexibility to work remotely, and to come together on campus for meaningful in-person collaboration and connection when it matters most.

What You’d Be Doing In This Role:

• Lead high-complexity investigations involving sophisticated techniques and potential legal or regulatory considerations.
• Coordinate closely with Legal, People, and Security teams on investigation scope, evidence handling, privacy considerations, and response activities.
• Write detailed investigation reports documenting findings, evidence, impact, and recommendations for technical and non-technical stakeholders.
• Respond to security events from detection through to containment, remediation, and resolution.
• Create and improve detection logic, correlation rules, and alerts across SIEM and EDR platforms.
• Proactively run threat hunting and anomaly detection exercises across Canva’s environment.
• Design and improve scalable tooling, workflows, and operational processes that strengthen Canva’s incident detection, investigation, and response capabilities.
• Act as an escalation point and incident coordinator during active investigations and security incidents.
• Participate in a collaborative on-call rotation supporting critical security investigations and incident response activities.
• Mentor and support the growth of teammates through knowledge sharing, operational guidance, and investigation best practices.

You’re probably a match if:

• You have experience leading or coordinating security investigations, digital forensics, or incident response activities in complex environments.
• You’re comfortable working cross-functionally with Legal, People, and Security teams, and can communicate clearly during high-pressure situations.
• You’re able to translate complex technical concepts for diverse audiences, including non-technical stakeholders.
• You’ve built or improved detection, automation, case management, or response workflows at scale.
• You have hands-on experience investigating macOS environments, alongside Linux and Windows systems.
• You’re comfortable designing, building, and improving security tooling and operational workflows.
• You’re confident working with SIEM, EDR, endpoint telemetry, and security investigation tooling.
• You enjoy solving ambiguous problems and proactively improving systems, processes, and operational maturity.
• You bring empathy, sound judgement, humility, and a collaborative mindset to sensitive investigations and incident coordination.
• You have programming or scripting experience in languages such as Python, Golang, or Java.

Nice To Have Experience:

• Experience with insider threat programs or user behaviour analytics (UBA/UEBA).
• Familiarity with DLP technologies and endpoint monitoring solutions.
• Experience building security automation or orchestration tooling.
• Exposure to legal evidence handling, privacy investigations, or law enforcement collaboration.
• Experience operating in cloud-native or large-scale SaaS environments.
