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 Engineer to support this need as a hands-on engineer, but also to lead the design and evolution Developer ecosystem as a Product Owner, or in a Scrum Master capacity. This role focuses on building intuitive, self-service workflows that enable development teams onboard, deploy, and operate software efficiently across secure environments. You will operate at the intersection of product, platform, and users — maintaining and 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 support the role as a Product Owner yet still have your hands on the design and implementation and 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. Note This Position will be based out of Aurora Colorado but may be supported Hybrid at either Richardson TX; or Dulles VA: if local to these other areas. What You Will Do Provide Product Ownership to the deliverable design.Implement user-focused workflows for onboarding, resource provisioning, and lifecycle managementDevelop 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 other platform teams to convert infrastructure capabilities into self-service productsImprove usability, adoption, and developer satisfaction across the platformGather feedback from engineering teams and translate it into product improvementsCreate documentation
