Job summary

At Atlassian, the Enterprise Security Engineer will implement and operate security controls across identity, endpoints, cloud, and data protection. The role partners with IT and security teams to deliver scalable security improvements in Atlassian’s corporate environment and internal tooling.

As part of the Customer Zero initiative, you’ll validate security capabilities internally before broader adoption, drive automation, and contribute to runbooks and SOPs across multiple platform domains.

Qualifications

• 3–5+ years of experience in cybersecurity, security engineering, cloud security, systems engineering, or enterprise technology.
• Experience implementing, operating, and maintaining security controls across identity, endpoint, SaaS, cloud, network, and data protection domains.
• Hands‑on experience with IAM, directory services, SSO/MFA, and access governance (e.g., Okta, Google Workspace, Azure AD / Entra ID).
• Practical experience securing cloud environments (AWS or GCP) and enterprise SaaS collaboration suites (e.g., Google Workspace, Slack).
• Experience automating security tasks and operational workflows using scripting (e.g., Python, Bash, Go), REST APIs, and CI/CD pipelines.
• Working knowledge of endpoint security architectures, device posture management (MDM), and data protection / DLP controls across macOS and Windows.
• Understanding of SaaS vendor risk assessments, third‑party integration risks, and secure baseline standards.
• Foundational awareness of cyber‑related physical access‑control systems and their integration with enterprise identity lifecycles.
• Strong troubleshooting and communication skills, with the ability to write clear runbooks and technical documentation, and collaborate effectively across engineering and operations teams.

Responsibilities

• Design, implement, operate, and maintain security controls across identity, endpoints, network, cloud, SaaS, and data‑protection domains.
• Remediate identified gaps in access controls, device posture, SaaS configurations, and sensitive data protections.
• Assist with the rollout and adoption of secure baseline configurations and paved‑path implementations across internal teams.
• Participate in security reviews for new tools, internal workflows, and SaaS integrations under the guidance of senior engineers.
• Support cyber‑related physical security operations, including maintaining integrations between physical access‑control systems and identity platforms, monitoring access lifecycles, and addressing facility‑related cyber risks.
• Strengthen identity lifecycle management, privileged access, authentication, authorisation, and access reviews.
• Help validate agentic identity, AI‑native governance, data‑protection, and access controls internally before broader release.
• Monitor insider risk signals, anomalous access patterns, and policy violations to support triage and response.
• Support the secure implementation of service accounts and automated bot credentials.
• Implement and monitor security guardrails and posture baselines across cloud environments (AWS/GCP) and SaaS suites (Google Workspace, Slack, Okta).
• Maintain endpoint security agents, device compliance policies, and configuration baselines across macOS and Windows fleets.
• Help implement and tune Data Loss Prevention (DLP) and data‑classification controls to safeguard internal and customer information.
• Build scripts, API integrations, and automations (e.g., Python, Bash, Go) to eliminate repetitive tasks and streamline security operations.
• Maintain infrastructure‑as‑code and CI/CD security checks for enterprise tooling.
• Track operational metrics, monitor control health, and contribute to SOPs and runbooks.
• Participate in on‑call rotations, troubleshooting, and post‑incident reviews (PIRs) for security tooling outages, pipeline failures, and platform availability issues.
