Collaborate with cybersecurity, development, and infrastructure teams to design secure identity solutions aligned with DoD and DISA standards.
Conduct system hardening, monitoring, log analysis, and performance tuning across Linux‑based ICAM components.
Perform systems integration tasks such as API‑based connectors, service integrations, and automated provisioning/deprovisioning workflows.
Support architectural reviews, internal control assessments, and risk management activities related to ICAM operations.
Diagnose and resolve escalated ForgeRock/ICAM issues within defined SLAs, including root‑cause analysis and corrective action development.
Create, maintain, and version-control engineering documentation including CONOPS, SOPs, API interface documentation, and workflow diagrams.
Provide input to audits, ATO support, compliance adherence, and continuous improvement initiatives.

Hands‑on experience with federation technologies (SAML, OAuth2, OpenID Connect) and Zero‑Trust identity principles.
Experience engineering or administering the ForgeRock platform (AM, IDM, DS).
Strong understanding of ICAM concepts, identity lifecycle management, and enterprise access controls.
Experience with Windows and Linux systems administration, shell scripting, system tuning, and troubleshooting.
Ability to work across highly technical and non‑technical teams in a fast‑paced environment.
