Lead Platform Architect

We are seeking a Lead Platform Architect to provide technical leadership and architectural oversight across a complex ecosystem of interconnected platforms shared services and mission capabilities.

The Lead Platform Architect will define and maintain the overarching technical architecture that enables multiple platforms to operate as a cohesive enterprise capability. This role will establish architectural boundaries interfaces shared services communication patterns and technical standards while enabling individual platform teams to maintain ownership of detailed implementation within their respective areas.

Because the platform ecosystem will continue to evolve the Lead Platform Architect will design for flexibility interoperability and long-term sustainability ensuring platforms can be added replaced consolidated or retired without requiring broad redesign of the overall environment.

• Define and maintain the overall technical architecture across cloud on-premises and security-domain environments.

• Establish architectural boundaries responsibilities interfaces and shared-service patterns between platforms.

• Develop architecture patterns that allow individual platforms to evolve independently while minimizing unnecessary cross-platform dependencies.

• Maintain reference architectures interface principles technical standards and architecture decision records.

• Ensure architectural decisions support long-term scalability resilience portability supportability and technology insertion.

• Define common architectural approaches for APIs messaging identity authorization service discovery data exchange observability and software delivery.

• Identify capabilities that should be implemented as shared enterprise services rather than duplicated across individual platforms.

• Evaluate major design changes for cross-platform impacts and resolve architecture-level conflicts and dependencies.

• Establish architectural patterns that enable interoperability across diverse platforms and deployment environments.

• Balance standardization with the flexibility required for platform-specific implementation and mission needs.

• Lead architecture and technical-design reviews spanning multiple engineering and platform teams.

• Partner with platform leads cybersecurity DevSecOps infrastructure G2PS ITSM and mission engineering teams to ensure architectural alignment.

• Guide technology selection modernization and replacement decisions while minimizing unnecessary vendor-specific dependencies.

• Evaluate proposed technical changes and assess their impacts across systems platforms interfaces and engineering organizations.

• Communicate architecture decisions risks dependencies tradeoffs and recommendations to program and customer leadership.

• Provide technical direction and architectural guidance while allowing platform-specific engineering teams to retain detailed implementation ownership.
