Overview

Leidos’ Digital Modernization sector is seeking a Systems Engineer with strong Dev Sec Ops , identity security, and systems‑integration expertise to support the Defense Information Systems Agency (DISA) Compartmented Enterprise Services Office (CESO). This role will contribute to the engineering, deployment, automation, and sustainment of an Identity‑as‑a‑Service (IDaaS) platform that underpins CESO’s Zero‑Trust Architecture and cross‑domain capabilities.

The engineer will work hands‑on with Ping Identity components, enterprise directory services, automated pipelines, and large‑scale ICAM integration patterns across secure environments. This position is 100% on‑site in Arlington, VA.

• Engineer, deploy, integrate, secure, and maintain Forge Rock IdP/ICAM components within complex, mission‑critical environments.
• Apply Dev Sec Ops  practices—including CI/CD pipelines, automated provisioning, configuration‑as‑code, and repeatable deployment patterns—to ICAM services.
• Integrate ICAM services with enterprise directory architecture, federation services, Zero Trust controls, and cross‑domain workflows.
• Implement and maintain access management functions including SSO, identity federation (SAML, OAuth2, OIDC), authentication flows, and policy enforcement.
• 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 Forge Rock/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.
• Develop and maintain ICAM performance metrics, identity lifecycle reports, and engineering dashboards.
• Partner with development teams to automate user, group, and credential workflows across secure enclaves.

• BS in Computer Science, IT, or related discipline and 8+ years of systems engineering experience (or equivalent experience in lieu of degree).
• Active TS clearance with SCI eligibility.
• Ability to obtain and maintain a CI Poly and Special Program Access.
• IAT Level II certification or higher (e.g., Security+ CE, CySA+, SSCP, CISSP).
• Hands‑on experience with federation technologies (SAML, OAuth2, OpenID Connect) and Zero‑Trust identity principles.
• Experience engineering or administering the Forge Rock 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.
• Strong communication skills and the ability to translate complex identity/security concepts to diverse audiences.

• Experience supporting DISA or DoD mission partners.
• Active TS/SCI with CI Poly preferred.
• Experience with any of the following:
  • JISG Access Controls
  • AWS cloud engineering, IAM, and security services
  • Ansible playbooks and automated configuration management
  • CI/CD pipelines (Git Lab, Jenkins, etc.)
  • API gateway, identity orchestration, or cross‑domain service integration patterns
