The Product Security team at Atlassian is committed to ensuring the delivery of secure products. These teams are geographically distributed, with a presence in the USA, Australia, and India. Each team is structured uniformly to provide comprehensive product security services tailored to their respective time zones. These services include security consulting, risk identification, and mitigation consulting for all products within their purview.
Recognising the critical importance of product security as a customer necessity and a competitive edge, our team holds a pivotal position within the organisation. With Atlassian's strong engineering focus and emphasis on autonomous teams, maturing the security of this complex environment stands as our core duty. Our tasks encompass identifying potential security threats in our products, devising suitable mitigation strategies, and evaluating their effectiveness on a large scale.

You will partner closely with engineering leadership, platform teams, and principal architects to define secure-by-default standards, architect scalable guardrails, and lead cross – organisational initiatives that protect Atlassian’s cloud environments at global scale.
In this role, you will operate at the intersection of deep technical leadership and strategic influence – diving hands-on into complex architectural designs, critical codebases, and high-severity escalations, while steering long-term security roadmaps and mentoring senior engineers across the organization. You will systematically identify systemic risks, design resilient mitigations, and ensure our cloud platforms deliver world-class security, reliability, and trust for over 300,000+ customers.

Partnering closely with security leadership, principal architects, and platform engineering teams, you will champion strategic programs that uplift and scale our security posture across multi-cloud environments. Some of your key responsibilities will include:
Strategic Architecture & Secure Design: Define and steer the overarching security architecture for multi-cloud platforms (AWS, GCP, Azure), setting company-wide secure-by-default standards, architectural patterns, and guardrails for cloud-native services and core platforms.
Complex Threat Modeling & High-Impact Assessments: Drive advanced threat modeling and deep-dive security assessments across critical, complex systems, distributed microservices, and high-assurance environments (such as Isolated, Private, and Regulated/FedRAMP offerings).
Platform Automation & Guardrails at Scale: Architect, champion, and scale automated security controls, detection capabilities, and self-healing guardrails embedded directly into CI/CD pipelines and infrastructure as code (IaC), systematically eliminating classes of vulnerabilities.
Continuous Posture Optimization & CSPM Strategy: Set the technical direction for Cloud Security Posture Management (CSPM) and posture analytics, driving continuous compliance, maturing security baselines, and providing leadership visibility into systemic risk.
Operational & Architectural Excellence: Establish company-wide reusable security frameworks, engineering guidelines, and operational standards that improve resilience, reliability, and security performance across Atlassian products.
