You will work at the intersection of identity security and user experience, ensuring that authentication systems are correctly configured, performing reliably at scale, and aligned with the organization's security policies. This is a proactive role where you will identify gaps in authentication coverage, evaluate emerging authentication technologies, and work across teams to drive adoption and strengthen the organization's overall identity security posture.

If you bring deep technical knowledge of authentication systems, experience integrating them across complex enterprise environments, and the communication skills to support both technical teams and end users, we want to hear from you.

Notes:This position is contingent upon additional funding and requires a Public Trust background investigation. This entails an in-depth background check & either US Citizenship or Permanent Resident (Green Card) status.

• Hands-on experience deploying and managing enterprise MFA platforms (e.g., Microsoft Authenticator, Duo, RSA SecurID, or equivalent)
• Strong understanding of modern identity and authentication protocols including SAML, OAuth 2.0, OpenID Connect, and RADIUS
• Experience integrating MFA solutions with Active Directory, Azure Active Directory, and Single Sign-On (SSO) platforms
• Ability to troubleshoot authentication failures across complex, multi-system enterprise environments
• Experience developing and enforcing MFA policies aligned with organizational security standards and zero-trust principles

Identity & Access Management

• Working knowledge of enterprise identity and access management (IAM) frameworks and platforms
• Familiarity with Microsoft Active Directory, Azure Active Directory, and related Windows-based systems
• Understanding of privileged access management (PAM) concepts and how authentication controls integrate within that model
• Ability to support risk assessments and security continuous monitoring efforts related to identity and authentication
• Ability to support large, cross-functional projects and communicate clearly with both technical and non-technical stakeholders
• Experience creating and maintaining clear documentation for authentication configurations, procedures, and troubleshooting guides
• Comfortable working with end users and support teams to resolve authentication issues and support MFA adoption at scale

A minimum of 3+ years of experience in identity and access management, with direct hands-on experience deploying and managing enterprise authentication and MFA solutions. Candidates with experience supporting large-scale MFA deployments or authentication migrations will be strongly preferred.

• Scripting and automation experience in Power Shell, Bash, Perl, or VBScript to support authentication administration and reporting
• Experience with cloud-based identity platforms such as Microsoft Azure or AWS IAM
• Familiarity with Web Authn / FIDO2 and passwordless authentication technologies
• Knowledge of zero-trust security principles and how modern authentication fits within that framework
