Responsibilities

• Design, develop, and execute test cases, test scripts, and comprehensive test plans to validate software functionality, performance, and compliance with requirements and acceptance criteria.
• Test new capabilities in modeling and simulation threat software, document new features, and analyze simulation performance to ensure accuracy and reliability.
• Develop detailed test artifacts, including test plans, test cases, test reports, and performance metrics, to support traceability and verification of system and software requirements.
• Verify and validate system and software requirements, ensuring full traceability between requirements, test cases, and test results.
• Execute and support system integration testing, regression testing, performance testing, and end‑to‑end testing for complex software solutions.
• Support the agile software development team within the context of a larger program, collaborating closely with systems engineers, software developers, and product owners.
• Contribute to sprint planning by estimating testing tasks and working with the team to ensure on‑time delivery of high‑quality deliverables.
• Support the development of simulation and software architecture by providing test‑driven feedback and identifying risks and gaps from a quality perspective.
• Research technical details related to missile defense systems, command and control, and modeling and simulation domains to better support software development and testing activities.
• Identify opportunities to enhance test strategies, tools, and processes, and recommend improvements to increase efficiency, coverage, and software quality.
• Act as a quality advocate within the team, promoting best practices in testing, documentation, and requirements verification.
• Provide hands‑on training sessions and demonstrations for end users to ensure proper understanding and effective utilization of the software.
• Collaborate effectively with technical teams and customer personnel through clear written, verbal, and interpersonal communication.
• Support integration of tests into CI/CD pipelines and, where applicable, automated API and system‑level testing to streamline delivery.
• Travel up to 10% of the time to support business needs such as integration events, demonstrations, or coordination with external teams.
