Job Description

We’re a team of hungry, high-character professionals from all backgrounds who came together to reinvent work for the modern enterprise. And we’re always looking for world-class human beings (not resumes) to join the movement.

Island, the Enterprise Browser is the ideal enterprise workplace where work flows freely while remaining fundamentally secure. With the core needs of the enterprise naturally embedded in the browser itself, Island gives organizations complete control, visibility, and governance over the last mile, while delivering the same smooth Chromium-based browser experience users expect. What we’re building now - it’s not another solution. It’s a whole new chapter for enterprise work.

As a Security Operations Lead at Island, you will operationalize and enhance the security of the Island Enterprise Browser by building proactive security controls, monitoring for real-world threats, and driving rapid response initiatives. You will play a critical role in safeguarding our infrastructure and customer environments, shaping the operational backbone of our security posture through precision, innovation, and real-world vigilance.

• Operational Security Automation: Develop custom automation for detection, alerting, triage, and response workflows; optimize signal-to-noise ratio to enable fast and accurate threat detection.
• Threat Intelligence & Hunting: Collect, analyze, and operationalize threat intelligence relevant to our threat model; conduct proactive threat hunting activities tailored to the enterprise browser domain.
• Security Operations Playbooks: Create and maintain incident response guides, runbooks, and operational playbooks to enable structured, high-fidelity security operations and empower cross-functional teams.
• Security Enablement & Awareness: Collaborate with product, engineering, and IT teams to improve security awareness, deliver training, and drive adoption of security best practices across Island.

Requirements

• Proficiency in scripting and automation (e.g., Python, Bash, PowerShell) to build scalable security tooling.
• Hands-on experience (3+ years) with SIEM, EDR, cloud security monitoring, and incident management.
• Familiarity with cloud security (AWS/GCP/Azure) principles and secure DevOps practices.
• Solid grasp of modern attack techniques, threat actor behaviors, and vulnerability exploitation patterns.
• Curiosity-driven, operations-focused mindset with a passion for keeping adversaries out and operations resilient.
