Federal Security Platforms Lead (Principal Information Security Engineer)

We are looking for a Federal Security Platforms Lead (Principal Information Security Engineer) to join our Enterprise Security team. This is a full-time onsite role based in Crystal City, VA, reporting to the Director of Federal Security Operations. 
You will build and own the security detection and response platform for a new, dedicated DoD/DoW IL6 cloud environment. In this role, you will architect Splunk Enterprise Security from the ground up, establish critical data pipelines and deliver high-fidelity automation to enable real-time threat response. Partnering across Zscaler, you will ensure our 24/7 federal security operations remain scalable, compliant, and mission-ready.

What you’ll do (Role Expectations)

• Architect, implement, and optimize Splunk Enterprise Security from the ground up, including ingestion pipelines, CIM normalization, indexer/search head clustering, and HA/DR across DoD IL6 environment
• Design, build, and tune high-fidelity detections mapped to MITRE ATT&CK and DoD threat profiles while managing the full content lifecycle, QA, version control, and false-positive reduction
• Define telemetry requirements and lead onboarding for cloud, endpoint, identity, and network sources to ensure data quality, normalization, and enrichment to close coverage gaps
• Develop SOAR automation and triage workflows, deliver analyst-facing dashboards and hunt workspaces, and partner with Incident Response for operationalization and continuous improvement
• Operate the SIEM/SOAR platform for a 24/7 environment and ensure configurations, retention, encryption, and RBAC align with FedRAMP, DoD CC SRG, and DISA STIGs

Who You Are (Success Profile)

• You thrive in ambiguity. You're comfortable building the path as you walk it. You thrive in a dynamic environment, seeing ambiguity not as a hindrance, but as the raw material to build something meaningful.
• You are a problem-solver. You seek out challenges because you are energized by finding solutions, knowing that solving the hard problems delivers the biggest impact.
• You are a high-trust collaborator. You are ambitious for the team, not just yourself. You embrace our challenge culture by giving and receiving ongoing feedback—knowing that candor delivered with clarity and respect is the truest form of teamwork and the fastest way to earn trust.
• You operate with urgency. You understand that in a high-growth environment, speed and quality are not mutually exclusive. You have a relentless focus on execution and a bias for action, delivering high-impact results quickly to win for the customer and the team.
• You are a pragmatic builder. You are obsessed with creating, iterating, and shipping. You aren't afraid to roll up your sleeves and build the first version yourself, balancing the drive for technical excellence with the need to deliver value to users quickly.

What We’re Looking for (Minimum Qualifications)

• US Citizenship and an active U.S. Secret Security Clearance (Top Secret preferred), with a willingness to participate in an on-call rotation (nights and weekends)
• 8+ years of security engineering or operations in FedRAMP/DoD environments, supporting 24/7 mission needs
• Experienced in architecting, administering, and optimizing clustered Splunk Enterprise Security deployments, including ingestion pipelines and CIM normalization across GovCloud/Secret regions
• Skilled at configuring data retention, encryption, and indexer/search head clustering for resilient, compliant log management aligned to FedRAMP and DoD CC SRG
• Proficient in SPL to build and tune correlation searches, dashboards, and risk-based alerting; partnered with IR to improve signal quality and reduce false positives

What Will Make You Stand Out (Preferred Qualifications)

• Experience operating in U.S. government cloud regions (AWS GovCloud/Secret; Azure Government/Azure DoD/Azure Secret) with DoDIL6 constraints
• Have or be able to obtain advanced DoD 8140 DCWF certification
• Expertise automating security workflows with Python or PowerShell, including SOAR playbooks, enrichment pipelines, and CI/CD for content deployment
