Requirements:

• Degree or equivalent, typically with 7+ years of relevant experience.
• 5+ years of professional software engineering experience, including ownership of production applications, services, platforms, or distributed systems.
• 2+ years of hands-on identity, authentication, authorization, or security engineering experience.
• Strong programming skills in Java, C#, Python, or a comparable object-oriented or backend language.
• Production experience integrating applications with a modern identity provider such as Okta, Microsoft Entra ID, Auth0, or Ping Identity.
• Production experience with OAuth 2.0, OpenID Connect (OIDC), and SAML.
• Experience modernizing or migrating applications from legacy authentication technologies such as LDAP, Active Directory, SiteMinder, or custom authentication services.
• Hands-on experience using Terraform to provision and manage infrastructure or platform configuration as code, including reusable modules, source control, review, testing, and deployment practices.
• Experience building or supporting REST APIs, microservices, or distributed applications in security-sensitive production environments.
• Experience with CI/CD and automated software delivery practices.
• Experience applying secure engineering practices to authentication, authorization, secrets, sessions, or access controls.
• Preferred: Deep hands-on Okta experience, including SSO, MFA, lifecycle management, provisioning, policies, and application integrations.
• Preferred: Experience managing Okta configuration through Terraform and implementing SCIM-based provisioning or identity lifecycle automation.
• Preferred: Experience with AWS, Azure, or GCP; Docker, Kubernetes, or other cloud-native technologies; and relational or NoSQL persistence technologies.
• Preferred: Experience with identity threat modeling, Zero Trust, least privilege, or policy-based access controls.
• Preferred: Experience in healthcare, financial services, insurance, life sciences, or another regulated environment, and familiarity with HIPAA, SOC 2, or comparable controls.

• Design identity integrations using OAuth 2.0, OIDC, SAML, and SCIM.
• Develop secure services, APIs, and integrations for authentication, authorization, provisioning, and identity workflows.
• Collaborate with application engineers, architects, product owners, and security teams to turn identity and access requirements into scalable technical solutions.
• Incorporate identity configuration and security controls into CI/CD pipelines, including automated testing and deployment.
• Review code and technical designs for authentication and authorization correctness, secrets management, session handling, and secure engineering practices.
• Diagnose complex production identity issues involving tokens, sessions, federation, provisioning, application integrations, and access policies.
• Help shape the architecture and roadmap for consolidating identity capabilities and retiring legacy authentication technologies.
• Mentor engineers on secure software development, identity patterns, IaC practices, and authentication architecture.
• Produce technical documentation, identity-flow diagrams, deployment patterns, and operational runbooks.
• Partner with security, risk, and compliance teams to develop identity solutions suited to a regulated healthcare environment.
• Deliver production-ready identity capabilities and reusable patterns that engineering teams can reliably adopt.
