The Software Quality Engineer II role involves ensuring the quality and reliability of software products through comprehensive quality assurance practices. This position requires a solid understanding of all stages of the software development lifecycle and the ability to apply software assurance standards in various contexts. The role includes assisting with test case design, performing integrated testing, and overseeing the software assurance process during requirements verification, certification, and customer and supplier oversight.

In this role, you will participate in all stages of the software development lifecycle, from requirements gathering and analysis to design, implementation, testing, and maintenance.

Additionally, you will perform requirements verification and ensure traceability throughout the development process while overseeing the software assurance process during certification and customer and supplier oversight. You will track and report software defects, working with development teams to resolve issues, and collaborate with cross‑functional teams to ensure software quality throughout the development lifecycle. Furthermore, you will provide clear verbal and written communication of quality assurance activities and findings and contribute to continuous improvement initiatives within the quality assurance process.

Our mission is driven by an unyielding commitment to advancing space‑based technology in service of our customers and safeguarding national security.
