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.

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.

• Architect and implement an Internal Developer Portal (IDP)
• Design user-focused workflows for onboarding, resource provisioning, and lifecycle management
• Develop frontend experiences using modern web frameworks (React/Type Script)
• Implement backend services and APIs supporting the portal (Python/FastAPI)
• Integrate platform systems (Kubernetes, CI/CD, identity, secrets, cost services, and infrastructure automation)
• Partner with platform teams to convert infrastructure capabilities into self-service products
• Improve usability, adoption, and developer satisfaction across the platform
• Define and evolve developer experience standards and patterns
• Gather feedback from engineering teams and translate it into product improvements
• Create documentation and enablement materials
• Communicate technical concepts to both engineers and leadership

• 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)
• Experience in one or more of the following
  • Programming:
    Python, Java, Type Script, 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:
    Postgre
    
    SQL, MongoDB
  • Product tooling:
    Jira / Atlassian ecosystem
  • Observability platforms
  • Generative AI developer tooling
