About the role 

Fusion92 is an award-winning Marketing Transformation Partner that helps brands solve complex business challenges through data, technology, and innovation. We move fast, think boldly, and embrace a culture that rewards curiosity and fearless problem-solving. As we continue to deepen our investment in AI and data-driven initiatives, we are expanding our security function to match that ambition. 

The right candidate is someone who lives and breathes security, serving as a trusted authority on both current threats and the evolving landscape. This role carries real organizational weight: the security champion for a company at the leading edge of AI and marketing innovation, responsible for ensuring that as Fusion92 pushes forward, it does so with the controls, visibility, and confidence to back it up. 

This is a cross-departmental role spanning IT & Technical Operations, Platform, Product & Innovation, and Compliance. Day-to-day security operations are part of the job, but so is the bigger picture: identifying gaps, governing the security implications of AI adoption, shaping how we mature our infrastructure, and contributing meaningfully to where Fusion92 goes next. This candidate will have real latitude to recommend and implement improvements, and the opportunity to build security capability across the broader team over time. 

What you’ll do 

• Triage and respond to security alerts across Huntress, Blumira, and Microsoft Entra ID, investigating risky sign-ins, anomalous behavior, and policy violations 
• Manage and optimize endpoint security tooling, including SentinelOne and other EDR/EPP platforms, ensuring coverage, policy enforcement, and timely response across the device fleet 
• Assess and help govern the security implications of AI tool adoption across the organization, evaluating data access, integration permissions, and acceptable use boundaries as new AI initiatives are introduced 
• Collaborate with the Platform, Product & Innovation team to ensure security controls and governance frameworks are built into AI and data-driven projects from the outset, rather than retrofitted after deployment 
• Investigate security incidents end-to-end and produce clear documentation for technical and leadership audiences 
• Audit security configurations against established policies, identify implementation gaps, and surface findings with recommended remediation paths 
• Review and validate Conditional Access policies, MFA configurations, and identity hygiene across Microsoft Entra ID 
• Conduct vulnerability assessments and coordinate remediation with relevant IT and infrastructure owners 
• Perform routine audits of user access, privileged accounts, application permissions, and SaaS integrations 
• Support compliance gap analysis against SOC 2, NIST, and CIS Controls frameworks and contribute to the organization’s regulatory readiness roadmap 
• Evaluate security tools and processes and provide input on improvements that would meaningfully strengthen our posture 
• Assist in training junior IT staff on incident identification and response, progressively delegating routine work as their skills develop 
• Stay current with the evolving threat landscape, including AI-specific risks, and bring relevant insights back to the team 

Requirements
