:

Parsons has emerged as a leader in developing and delivering cutting-edge solutions to the Department of Defense and the Intelligence Community by staying relentlessly focused on mission impact and investing in exceptional people. Our success is driven by close collaboration with operators and analysts, ensuring the systems we build are not only innovative but operationally relevant, intuitive, and effective in real-world environments.

Within our Space Operations directorate, we are focused on enabling mission-critical capabilities that support national security in an increasingly contested and dynamic space domain. We bring together experienced subject matter experts and highly skilled technologists to deliver resilient, scalable solutions that directly support operational decision-making and execution.

We are seeking a Systems Engineer with Software Engineering experience who wants to work on systems that matter, supporting operational, system-of-record capabilities used by the space community. In this role, you will be part of a high-performing Agile engineering team developing and sustaining distributed, integration-heavy mission applications. You will operate in a fast-paced environment where understanding end-to-end system behavior, interfaces, and data flows is critical to success.

If you are looking to grow your technical depth while contributing to real-world mission outcomes and want to be part of a team solving complex national security challenges in the space domain, we want you on our team.
