- Description This role is part of a growing program, and hiring will depend on available funding. We review applications on a rolling basis, but the timeline for interviews and offers may vary. In some cases, we may extend contingent offers that become active once funding is confirmed. This position is located in Gaithersburg, MD;
Egg Harbor Township, NJ; or Eagan, MN. This is an opportunity to contribute to projects that impact millions of air travelers.  This is a hybrid position requiring 3 days onsite and 2 days remote work.  Candidates should reside a commutable distance to one of the above locations.  Leidos is seeking a Principal Cloud & Platform Architect to join the Air Traffic Business Area within the Homeland Sector, supporting the development of the Leidos Common Automation Platform (L-CAP).

L-CAP is a mission-critical, future-ready automation platform built on a hybrid cloud data mesh architecture, enabling next-generation air traffic management capabilities. You will serve as the enterprise platform architect responsible for designing the hybrid cloud infrastructure and platform services that underpin the L-CAP automation platform. We are building with an AI-first engineering mindset, embracing emerging AI capabilities and modern development practices to accelerate delivery, improve software quality, and continuously evolve how we design and build mission-critical systems.

This position supports government programs and requires the ability to obtain and  maintain  a favorable Public Trust investigation.
What You'll Do :
* Design the hybrid cloud architecture spanning on-premises and cloud environments   
* Define Kubernetes orchestration strategy for containerized workloads at scale   
* Establish Infrastructure-as-Code ( IaC ) governance using Terraform   
* Architect FedRAMP-compliant platform designs across multiple environments   
* Design and govern CI/CD platform services for engineering teams   
* Lead capacity planning and infrastructure cost modeling   
* Define platform reliability standards including SLOs and SLIs   
* Design multi-environment deployment strategy (dev, test, staging, production)   
* Oversee container orchestration patterns and service mesh architecture   
* Drive cloud cost optimization and Fin Ops practices   
* Design platform architecture to host safety-critical ATC applications with deterministic performance characteristics rather than general enterprise IT workloads   
* Ensure operational resilience and failover capabilities for distributed real-time ATC services across hybrid cloud deployments   
* Define platform requirements for deterministic distributed services including latency guarantees and predictable resource allocation   
* Champion an AI-first engineering culture by  identifying  and applying AI-assisted development capabilities, automation, and emerging software engineering practices that improve developer productivity, code quality, testing, and delivery.
