We are seeking an experienced Network & Application Support Engineer to join our team in support of a critical, long-standing contract with the National Geospatial-Intelligence Agency (NGA). This role offers a unique balance between maintaining the stability of legacy systems and driving the innovation of new capabilities. The ideal candidate will be deeply customer-focused, ensuring all technical deliverables align with the NGA’s operational mission and strategic goals. While you will enter an environment with established stability and a deep institutional knowledge base, the evolving needs of the NGA ensure the work remains challenging and forward-looking. This dual-function role encompasses both the engineering of sophisticated enterprise computing infrastructure and the critical 24/7 operational sustainment of customer applications. The successful candidate will provide engineering services for network infrastructure—including cloud services, containerized solutions, and virtualized applications—while ensuring the day-to-day stability of customer applications and segment interfaces. This role interfaces directly with engineering resources across multiple facilities and serves as the high-level technical escalation point for complex system anomalies. This position offers significant growth potential, providing a pathway to transition from a technical expert into a leadership role as you help shape the future of geospatial intelligence capabilities. Key Responsibilities: • Infrastructure Engineering & Optimization • Cloud & Virtualization: Build and manage VPCs with Linux VMs using commercial cloud providers (eg. AWS), configuring them as network appliances and ensuring they meet strict cybersecurity standards. • Network Hardening: Configure and harden network hardware, including firewalls, switches, routers, and IPS, as well as Linux OS in both cloud and physical environments. • Architecture Support: Provide expertise in core infrastructure, voice/video engineering, network analytics, and bandwidth service delivery. • Operations & Application Sustainment • Mission Support: Provide critical 24x7 mission support, monitoring customer applications and investigating segment interfaces to minimize operational impacts. • Triage & Resolution: Perform initial assessment, research, and technical assistance for hardware and software issues; isolate problems and implement permanent solutions. • Incident Management: Respond to technical requests via phone, email, or in person; log all interactions and track resolutions following standard help desk procedures and CONOPS. • SME Escalation: Act as a primary point of contact for problem escalation with vendors, factories, and other site Subject Matter Experts (SMEs). • Reporting: Prepare daily operational status briefings and maintain up-to-date knowledge of all system changes and updates. • Customer Engagement: Foster a collaborative relationship with the Customer to identify pain points and propose proactive technical solutions. • Strategic Planning: Contribute to the long-term technical roadmap of the contract, identifying opportunities for modernization and efficiency gains. Because of the need for consistent, in-person collaboration and the nature of this role, this position is performed 100% full-time on-site at a BAE Systems customer facility. Due to the 24x7 mission requirement, the candidate must be able to provide independent troubleshooting and resolution during after-hours and weekends (Call-in support).
