• Experience integrating applications into enterprise security stacks and identity environments (SSO, SAML, OIDC, LDAP, directory services)
• Demonstrated experience designing and delivering mission-critical solutions with high security, availability, and compliance requirements
• Ability to translate complex, sometimes security-sensitive requirements into clear architecture designs and implementation roadmaps
