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. ## Related Videos - [What makes Cybersecurity different for critical infrastructure?](https://www.wearedevelopers.com/videos/571-what-makes-cybersecurity-different-for-critical-infrastructure) - [JavaScript?
