Solution Architect​/Engineer

Leidos Solution Architect / Engineer Overview

Leidos is seeking a highly versatile and hands‑on Solution Architect / Engineer with broad expertise across enterprise networks, infrastructure, cloud platforms, and systems engineering. This role combines high level architectural design with deep technical implementation, requiring an individual who can define target‑state architectures, build and optimize solutions, and guide modernization across hybrid and multi‑cloud environments. The candidate will collaborate with cross‑functional teams to ensure solutions are scalable, resilient, secure, cost‑optimized, and aligned with long‑term business objectives.

Location: This work is located onsite in the DC area. Hands‑on implementation experience is critical — this is not a purely strategic/theoretical role.

• Serve as the Enterprise Architecture team lead; assigning and managing team tasks, conducting daily stand‑ups and status updates, preparing weekly consolidated reports, and delivering updates to the federal lead.
• Define and develop target infrastructure architectures across hybrid and multi‑cloud environments, networks, platforms, and enterprise systems.
• Design and implement end‑to‑end technical solutions, ensuring scalability, resilience, performance, and cost optimization.
• Lead infrastructure modernization initiatives, including evaluation of legacy systems, migration strategies, and adoption of new technologies.
• Engineer and deploy solutions across cloud platforms (AWS/Azure), virtualization environments, on‑premises datacenters, and containerized workloads.
• Architect and build network solutions including LAN/WAN, VPN, SD‑WAN, firewalls, load balancers, and cloud networking (VPC/VNet, subnets, gateways, routing, peering).
• Create detailed architectural diagrams, including data flow diagrams, integration maps, logical/physical infrastructure designs, and solution blueprints.
• Analyze and document system and application data flows to ensure secure, efficient, and reliable communication between components.
• Develop automation and code‑based solutions using Python, Power Shell, Bash, or similar languages, and infrastructure‑as‑code tools such as Terraform, Ansible, or Cloud Formation.
• Troubleshoot and resolve escalated, high‑level technical issues across networking, cloud, systems, and application layers.
• Evaluate and recommend technology platforms, integration patterns, and architectural standards based on business and technical imperatives.
• Ensure all solutions adhere to security, governance, and compliance frameworks (SOC 2, ISO 27001, HIPAA, PCI‑DSS).
• Support capacity planning, resiliency strategies, disaster recovery architecture, and business continuity design.
• Collaborate closely with project management team, engineering, security, and application teams throughout design, build, deployment, and optimization phases.
• Produce comprehensive technical documentation including architecture designs, data flow diagrams, engineering procedures, operational runbooks, and implementation guides.

• Bachelor’s degree in Computer Science, Information Technology, Engineering, or related field and 12+ years of relevant experience, or Master’s degree with 10+ years of relevant experience. Additional years of experience will be considered in lieu of a degree.
• 12+ years of progressive experience in enterprise architecture, infrastructure engineering, and cloud solutions.
• 12+ years in a leadership or lead architect role, including team task management, conducting stand‑ups, and delivering executive‑level status reports.
• Proven hands‑on experience designing and implementing solutions across hybrid/multi‑cloud environments (AWS and Azure strongly preferred), on‑premises data centers, virtualization platforms, and containerized workloads (e.g., Kubernetes/Docker).
• Strong background in enterprise networking including LAN/WAN, VPN, SD‑WAN, firewalls, load balancers, VPC/VNet, routing, peering, and related technologies.
• Demonstrated success leading infrastructure modernization, legacy system migrations, and large‑scale technical implementations.
• Experience with automation and scripting…
