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.

What You Will Do

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/TypeScript)

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

Qualifications You Must Have

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, TypeScript, Golang, Rust, Shell

Frameworks: React/Next.js, Flask, Spring Boot, Svelte

Containerization: Docker, Podman

Orchestration: Kubernetes, Rancher

Databases: PostgreSQL, MongoDB

Product tooling: Jira / Atlassian ecosystem

Observability platforms

Generative AI developer tooling

Ability to obtain a TS/SCI security clearance is required after day 1. U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance

Qualifications We Prefer

Experience building or supporting Internal Developer Platforms (IDPs)

Experience improving developer workflows or platform usability

Background in DoD, Intelligence, or Space environments

Experience working in scaled agile environments

Experience leading platform or product initiatives

Ability to understand Modern DevSecOps practices

Ability to understand Software testing methodologies

Experience with RESTful API and distributed architecture design

Experience with Secure system design principles
