Responsibilities
LMI is seeking a skilled Infrastructure Engineer to design, implement, automate, operate, and sustain the foundational computing platforms supporting enterprise applications, data, and mission services across a network of new and existing secure facilities. The Infrastructure Engineer will ensure that physical, virtual, and cloud-based environments remain reliable, secure, scalable, recoverable, and supportable. This is an execution-oriented role supporting a fast-paced, milestone-driven prototype effort with near-term deliverable commitments. Success requires strong compute, storage, operating-system, virtualization, platform, automation, and lifecycle-management fundamentals rather than expertise limited to a specific vendor.
Primary Duties Include:
- Enumerate and document the infrastructure baseline across geographically dispersed sites, including compute, storage, operating systems, virtualization, cloud services, backup, recovery, and platform dependencies.
- Design current-state, transition-state, and target-state infrastructure for secure facilities, data centers, cloud environments, and operational sites.
- Engineer physical, virtual, containerized, and cloud-based platforms based on mission, performance, availability, security, and recovery requirements.
- Establish platform standards, configuration baselines, reusable patterns, implementation procedures, and lifecycle roadmaps.
- Implement secure configurations, patching, hardening, encryption, access controls, and privileged-administration practices in coordination with cybersecurity personnel.
- Develop and validate backup, restoration, disaster-recovery, and continuity procedures for mission-critical services and data.
- Monitor infrastructure health, performance, capacity, utilization, configuration compliance, and emerging lifecycle constraints.
- Diagnose complex infrastructure issues involving compute, memory, storage, operating systems, virtualization, cloud services, and supporting dependencies.
- Automate infrastructure provisioning, configuration, patching, testing, monitoring, scaling, backup, recovery, and compliance using repeatable infrastructure-as-code and configuration-management practices.
FOUNDATIONAL SKILLS
- Compute, storage, operating systems, virtualization, containers, and cloud infrastructure.
- Platform architecture, availability, scalability, performance, and capacity engineering.
- Backup, restoration, disaster recovery, and continuity of operations.
- Identity, authentication, authorization, encryption, and privileged-access fundamentals.
- Secure configuration, patch management, system hardening, and vulnerability remediation.
- Infrastructure monitoring, telemetry, logging, and performance analysis.
- Network, distributed-system, application-hosting, and data-platform fundamentals.
- Automation, scripting, APIs, configuration management, infrastructure as code, and version control.
- Configuration, change, release, incident, problem, capacity, and technology-lifecycle management.
Location: This position is based in the Washington, DC metro area, with travel to program locations.
Travel: This position requires approximately 25-50% travel to support activities across multiple program locations.
Qualifications
Required:
-
- Bachelor's degree in Computer Science, Information Technology, Engineering, or a related field.

-
- Strong understanding of compute, storage, operating systems, virtualization, cloud, backup, recovery, and platform-security principles.
-
- Demonstrated ability to troubleshoot complex infrastructure issues across multiple technical domains.
-
- Experience engineering capabilities for SCIF or other accredited classified environments, including multi-enclave systems and security boundaries.
-
- Working knowledge of the Risk Management Framework (NIST SP 800-37 / 800-53) and experience advising senior leaders.
-
- Active Top Secret Clearance (SCI eligibility) required.
-
- Excellent communication skills both verbally and in writing. Ability to develop papers, reports, and briefings targeted to senior decision makers.
Nice to Have:
-
- Relevant infrastructure, cloud, systems engineering, automation, or cybersecurity certification.
-
- Experience integrating cross-domain solutions (CDS) into enterprise architectures.
-
- Experience supporting Special Access Program (SAP) facilities, systems, or environments.
-
- Experience designing or standing up network or security operations centers (NOC/SOC), including 24x7 coverage models.
