Network & Infrastructure Architect/Engineer

Who are we?

Dynamic Integrated Services (DIS) is a proud Service-Disabled Veteran-Owned Small Business based in the Washington, D.C. Metropolitan area providing management consulting services to federal agencies and organizations supporting the public sector. DIS offers exceptional client services in the areas of Strategic Communications and Integrated Marketing (SCIM), Information Technology (IT), and Enterprise Optimization (EO).

At DIS, we are team oriented, continuous learners, hard-working, creative thinkers, and most of all kind people. We are a different kind of company with a truly unique culture, we celebrate people in all forms; one that values our employees and shares a mutual devotion to serving our clients with the highest forms of integrity.

DIS is seeking a hands‑on Network & Infrastructure Architect/Engineer to support and enhance the connectivity, reliability, and observability of our enterprise EHR integration ecosystem. In this role, you will architect cloud and on‑premises network patterns, ensure secure and stable interface connectivity, monitor integration engines, and deploy telemetry that delivers end‑to‑end visibility across HL7/FHIR transactions, application workflows, and infrastructure components. You will contribute to Zero Trust–aligned controls, implement comprehensive logging and monitoring across OCI and connected systems, and collaborate closely with interface, platform, and identity teams to ensure safe, performant, and compliant integrations.

• Build and maintain OCI VCN architectures, including non‑overlapping CIDRs, public/private subnets, route tables, gateways (Internet/NAT/Service), DRG, and peering required for EHR interface connectivity.
• Implement segmentation across perimeter boundaries, production/non‑production environments, and tenancy/VCN constructs using NSGs for fine‑grained VNIC‑level control.
• Maintain network diagrams, address plans, baselines, and documentation supporting resilience, scalability, and hybrid connectivity between on‑premises systems and OCI.

• Configure and manage comprehensive logging across multiple domains:
• Application/Solution Logs
  : HL7/FHIR engine logs, middleware logs, interface transaction logs.
• Network Logs
  : VCN flow logs, gateway traffic logs, firewall/NSG events.
• Asset Logs
  : compute instance logs, patch/compliance data, system performance metrics.
• Security Logs
  : IAM events, anomaly detections, audit trails, endpoint telemetry.
• Implement and manage logging platforms including OCI Logging
  , Splunk
  , Crowd Strike Falcon
  , and related SIEM/SOAR integrations.
• Deploy monitoring and alerting across metrics, alarms, events, and dashboards; integrate with Grafana/Prometheus and route alerts to operational teams.
• Define and analyze KPIs/SLOs for HL7/FHIR interfaces (latency, error rates, retries), and use Open Telemetry to perform distributed tracing and end‑to‑end message correlation.

• Apply network and infrastructure controls that align with IAM requirements including phishing‑resistant authentication, least‑privilege access, and continuous session enforcement.
• Support Zero Trust advancement by implementing network‑level controls mapped to CISA's pillars and cross‑cutting capabilities.
• Maintain event logging and auditability mapped to NIST SP 800‑53 Rev. 5, especially for integration‑related assets.

• Retroactive analysis of previous networking projects for purposes of assessing issues and making recommendations.
• Communication of current network issues and gaps (e.g., lack of redundancy).
• Recommendation of solutions for detected problems.
• Provide comprehensive documentation of the DMM network infrastructure. Need to use Visio to draw maps.
• Assist in the development of proposals and supporting documentation for submission to upper management.
• Explain network device functions, interconnections, and ensure clarity on roles of supporting staff (e.g., why do we need to buy…
