About The Position

Grow your software engineering career with meaningful impact as a Software Integration and Test engineer working in the space domain! We are seeking a Software Integration and Test (SWIT) Engineer who wants to solve interesting, complex problems to protect our nation. As a SWIT engineer on this team, you will work in a team environment to design, develop, and implement test plans and procedures for software (SW) requirement verification & validation. You will be responsible for SW integration, requirement analysis, test planning and execution, performance analysis, troubleshooting and coordination for remediating software defects. In this role you will write test procedure scripts in Perl, Python, Linux, and with automated software test tools. In support of the test execution leads, you will conduct test walk throughs, and communicate plans, status and out-briefs with the IPT leads, team members, and the customer. If you're passionate about technology, ready to grow beyond junior-level work, and excited to make an impact on space mission systems, we would love to hear from you! What makes this role exciting: Deliver features independently - take ownership of well-scoped features from implementation through deployment. Expand your expertise - work with modern technologies (Python, Java, Spring Boot, React, AWS/Azure, Kubernetes) with increasing complexity. Collaborate and learn - work alongside senior and staff engineers who will help you level up your skills. Space domain impact - build software that directly supports critical space missions. If you're ready to take the next step in your career, build increasingly complex software, and contribute to systems that matter, let's talk!
