Job Description

Parsons is looking for an amazingly talented Software Architect to join our team!

In this role you will lead the architecture, technical evolution, and operational design of a large-scale, globally distributed mission platform deployed across multiple countries and managed remotely from the United States.

This platform supports real-time transaction processing, distributed data management, integration with external government and commercial systems, peripheral/device orchestration, and centralized observability and administration.

The successful candidate will be the overall software architecture authority for a modern Linux-based platform composed of approximately 25 core microservices and a broad set of supporting/integration services. The environment is cloud-heavy, distributed, operationally critical, and deployed in both constrained edge settings and larger centralized/cloud environments.

This role requires someone who can define and govern architecture while remaining grounded in the realities of runtime operations, resilience, fieldability, and maintainability.
