Job Responsibilities:

In this role, you will oversee the design, development, and execution of comprehensive software test plans, test cases, and test procedures to ensure the functionality, performance, and reliability of complex software systems.
You will architect and oversee the technical aspects of large-scale test campaigns for complex aerospace software systems, providing leadership in the innovation and adoption of new software test technologies and methodologies.
Collaborating with software developers, systems engineers, and other engineering functions, you will design effective test strategies and direct others in overseeing the defect lifecycle from discovery to resolution, ensuring fixes meet requirements.
You will lead the definition of software test risks and opportunities while managing cost and schedule impacts, guiding teams of software test engineers and providing mentorship to ensure high-quality deliverables.
Additionally, you will review, analyze, and contribute to the development of software design descriptions, ICDs, and requirements in coordination with software development teams, oversee software test trade studies such as test management tools and Continuous Integration Test techniques, and direct the development and execution of formal verification and qualification tests.
Managing test result analysis, generating test reports, and addressing issue definitions, investigations, and closures will be key, along with collaborating closely with cross-functional peers such as Program Management, Software Development, and Flight Operations to ensure quality throughout the software development lifecycle.
You will coordinate and define test roles and responsibilities across multiple simultaneous test campaigns, direct continuous improvement initiatives, and develop enterprise best practices in testing processes and methodologies.
