About The Position

At Raytheon, the foundation of everything we do is rooted in our values and a higher calling – to help our nation and allies defend freedoms and deter aggression. We bring the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today’s mission and stay ahead of tomorrow’s threat. Our team solves tough, meaningful problems that create a safer, more secure world. We are seeking a Principal Platform Architect to lead the design and evolution of our Internal Developer Portal and Developer Experience ecosystem. This role focuses on building intuitive, self-service workflows that enable development teams to onboard, deploy, and operate software efficiently across secure environments. You will operate at the intersection of product, platform, and users — translating developer needs into usable platform capabilities. The role requires strong frontend engineering instincts, backed by solid backend and cloud-native platform knowledge. You will help define how engineers interact with the platform — not just build services but design the experience. This position involves architecting UI workflows, integrating APIs, enabling self-service automation, and shaping platform standards used across multiple programs and security domains. What Makes This Role Unique This is not a traditional backend platform engineering role. You will design how developers interact with the platform itself — shaping onboarding, automation, and daily workflows across a large engineering organization. Success in this role is measured by developer adoption, efficiency, and satisfaction. You will be the person who turns infrastructure into a usable product.

Requirements

Typically requires BS/BA Degree in Science, Technology Engineering Math (STEM) in Computer Science, Computer Engineering, Information Technology or Physics and a minimum 8 years of related work experience
Experience with Windows and Linux operating systems (RHEL 8+ preferred)
Proficiency in one or more of the following: Programming: Python, Java, TypeScript, Golang, Rust, Shell; Frameworks: React/Next.js, Flask, Spring Boot, Svelte; Infrastructure as Code: Terraform, Ansible or equivalent; Data formats: JSON, XML, YAML, SQL
Experience in one or more of the following: Cloud platforms: AWS, Azure, or similar on-prem/self-hosted infrastructure; Containerization: Docker, Podman; Orchestration: Kubernetes, Rancher; Databases: PostgreSQL, MongoDB; Product tooling: Jira / Atlassian ecosystem; Observability platforms; Generative AI developer tooling
Active and transferable DOD TS/SCI security clearance is required on Day 1. U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance
