You'll work on systems where performance, precision, and reliability matter - every second. This is not experimental AI for prototypes. This is disciplined, responsible AI applied to mission-critical software that supports national infrastructure. If you're excited by solving complex problems in regulated, real-world environments - and using AI as a force multiplier rather than a shortcut - we'd like to talk. ## 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 andmaintaina 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 FinOps 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 byidentifyingand applying AI-assisted development capabilities, automation, and emerging software engineering practices that improve developer productivity, code quality, testing, and delivery. ## Related Videos - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) - [Understanding Kubernetes in a visual way](https://www.wearedevelopers.com/videos/100085-understanding-kubernetes-in-a-visual-way) - [Infrastructure as Code: The Developer's Secret Weapon](https://www.wearedevelopers.com/videos/1221-infrastructure-as-code-the-developer-s-secret-weapon) - [Rate-limiting using eBPF and Istio: How to protect your SaaS customers from themselves](https://www.wearedevelopers.com/videos/100220-rate-limiting-using-ebpf-and-istio-how-to-protect-your-saas-customers-from-themselves) - [Building a Cloud Platform Where Everything is Just Another Kubernetes Resource](https://www.wearedevelopers.com/videos/100137-building-a-cloud-platform-where-everything-is-just-another-kubernetes-resource) - [Reference Architecture of AI in the Cloud](https://www.wearedevelopers.com/videos/1613-reference-architecture-of-ai-in-the-cloud) ## Related Articles - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [7 Cloud Computing Trends Coming in 2025 for Developers](https://www.wearedevelopers.com/magazine/412-7-cloud-computing-trends-coming-in-2025-for-developers) - [Stephan Gillich - Bringing AI Everywhere](https://www.wearedevelopers.com/magazine/489-stephan-gillich-bringing-ai-everywhere) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [Got AI ideas but no money?
