A Mission Software Engineer develops and deploys software essential for a specific, real-world objective or "mission" in partnership with our customers.

The Mission Applications (MA) Group within the AC2 Division specializes in ensuring the STR technology produces outsized mission impact.

• Develop and maintain automated test scripts and test frameworks for Java applications

This role will take advantage of STR’s flexible, hybrid environment – when the work does not require use of STR’s or the customer’s facilities, you are welcome to work remotely.
