Systems Engineer

• Develop and maintain system architectures that ensure conformance to standards, requirements, and associated systems, utilizing DoDAF and other frameworks as specified by the Government.
• Provide preliminary and final designs, including system diagrams, design descriptions, and interface control documents, in support of project and customer requirements.
• Lead the integration of sensing software/hardware solutions with associated networks, validating software packages and devices.
• Design and test capabilities to address operational issues or shortfalls, ensuring seamless integration with existing systems.
• Develop and maintain the program’s Systems Engineering Plan (SEP) that aligns with program plans.
• Architect and develop Cyber Sensing Solutions designed to monitor the DoD telecommunications infrastructure, encompassing requirement analysis, design, and implementation at customer sites.
• Lead end-to-end architecture for mission systems across storage, network, security, data, and identity domains.
• Produce and maintain DoDAF views (OV, SV, CV, DIV) and system/solution architecture artifacts (logical/physical diagrams, interface control documents, data flow diagrams, sequence diagrams).
• Define capability roadmaps, technology standards, and reference architectures aligned to DISA/DoD policy, Cloud SRG IL2–IL6, and mission needs.
• Engineer for HA/DR/COOP, performance, scalability, and cost optimization; establish capacity models and SLOs/SLIs.
• Lead the design and integration of Windows/RHEL, virtualization (VMware/Nutanix), containers/Kubernetes/OpenShift, and GovCloud (AWS/Azure) services.
• Architect and implement ICAM/PKI/CAC, network services (DNS/DHCP/IPAM), load balancing, and edge/security services (SWG, WAF, proxies).
• Build Infrastructure-as-Code and Configuration-as-Code pipelines (Terraform, Ansible, PowerShell/Bash, GitLab/Jenkins/Azure DevOps) for secure, repeatable deployments.
• Integrate observability (SolarWinds, Prometheus/Grafana, Splunk/ELK) and design telemetry for proactive operations.
• Lead the RMF lifecycle from categorization to ATO/cATO, creating and maintaining SSP, SCTM/RTM, POA&M, test plans/evidence, and continuous monitoring dashboards.
• Apply DISA STIGs/SRGs, SCAP, ACAS/Tenable, HBSS/ESS/EDR baselines; drive remediation and control inheritance.
• Architect to Zero Trust principles (identity, device, network, app/data, analytics, automation); design micro-segmentation, policy enforcement, and continuous assessment.
• Partner with ISSM/ISSO and cyber operators to align controls with operational reality and mission risk.
• Provide Tier III technical leadership, conduct root cause analysis, and publish RCAs with corrective/preventive actions.
• Establish SOPs/runbooks, as-built documentation, change management artifacts, and operational dashboards tied to KPIs/SLAs.
• Participate in CABs, IPTs, design reviews, and readiness assessments; brief senior government stakeholders on trade-offs, risk, and performance.
• Serve as a technical lead for a cross-functional team (systems, network, security, DevSecOps, data).
• Mentor junior engineers and review designs/PRs for architectural compliance and secure coding/infrastructure patterns.
• Coordinate with vendors and DISA partners to evaluate COTS/GOTS solutions and conduct POCs.
