• Lead design sessions, collaborating with Enterprise Architecture, and implementation of IAM integrations for SaaS, on‐prem, and AWS cloud platforms, including federation (SAML, OIDC, OAuth), MFA, and Passwordless capabilities.
• Serve as the primary escalation point for complex IAM engineering issues; perform root‐cause analysis and drive long‐term remediation and hardening of IAM platforms and related services.
• Partner with security architecture, infrastructure, application, and HR/IT teams to align IAM solutions with enterprise security strategy, compliance obligations, and business objectives.
• Define IAM engineering standards, patterns, and reference architectures; guide other engineers in implementing secure onboarding patterns for applications into IGA, PAM, and SSO platforms.
• Lead modernization initiatives.
• Contribute to audits, risk assessments, and regulatory reviews by providing technical evidence, designing compensating controls, and closing identified IAM control gaps.
• Mentor and coach IAM engineers and analysts, promoting engineering excellence, documentation discipline, and a culture of continuous learning and improvement.

• 10+ years of experience in information security or infrastructure engineering, with at least 5 years of hands-on-keyboard experience with core IAM platforms.
• Deep expertise with the majority of our IAM stack.
• Strong hands-on experience with Microsoft Entra ID and Active Directory as foundational directory services, and extensive experience implementing federation protocols (SAML, OIDC, OAuth2).
• Proven track record designing and implementing IAM solutions in hybrid multi-cloud environments, including the automation of provisioning, access reviews, and RBAC/ABAC models.
• Experience with secrets management solutions.
• Proficiency in at least one scripting or programming language (such as PowerShell, Python, or Java) to automate tasks and build custom connectors for our IAM tools.
• Excellent communication skills with the ability to translate complex technical concepts related to our IAM ecosystem for both technical and non-technical stakeholders.
• Exceptional sense of ownership and the ability to work with a limited set of requirements.
• Highly advanced ability to breakdown work to deliver value incrementally.
• Experience leading large-scale IAM programs.
• Prior responsibility as a technical lead or architect for IAM, including mentoring teams and influencing roadmaps beyond direct reporting lines.
• Demonstrated ability to balance security, usability, and operational efficiency, with a strong bias toward automation and measurable risk reduction.
• Define and lead the implementation of the organization's security strategy, with a focus on Cloud Security, Identity Access Management, and all other aspects of Cybersecurity.
• Oversee the deployment of IAM solutions across both on-premise and cloud environments, ensuring they meet the highest standards of security.
• Lead the most complex security assessments, including threat modeling, red teaming, and cloud security reviews.
• Collaborate with executive leadership to ensure that security initiatives align with the organization's strategic goals and risk appetite.
• Act as the technical lead for large-scale security projects, coordinating cross-functional teams to ensure successful delivery.
• Architect and implement solutions across workforce IAM, PAM, and customer IAM ecosystems.
• Provide thought leadership in adopting passwordless authentication, passkeys, adaptive MFA, and AI-driven access orchestration strategies.
