What Your Job Will Be Like:

We are seeking Software Engineering professionals to join a high-performing team focusing on system integration and testing for space missions. In this role, you will have opportunities to collaborate on the design, development, testing, and deployment of advanced real‑time decision support ground systems. Work will include both manual testing using formal test procedures and automated testing using in‑house developed automation test tools.

You will work with experienced engineers and testers, receive mentoring, and progressively take on increasing responsibility while growing your skills in test automation, requirements‑based verification using formal test procedures, and system integration. As a mid‑career team member, you will be expected to independently drive test strategy and execution for assigned capabilities, influence design‑for‑test, and improve automation frameworks and practices across the team.

On any given day, you may be called to:

Lead collaboration with software architects, system engineers, developers, technical leads, customers, and end users to collect and analyze requirements and translate them into verification approaches, formal test procedures, and automated test designs.

Contribute to the design, development, and delivery of technology solutions that improve software quality by influencing system/test architecture and design‑for‑testability decisions.

Generate automated tests to verify system functionality and own the health, coverage, and maintainability of assigned automated test suites.

Plan and support formal test activities at multiple levels, from components to the enterprise system, including test readiness, execution leadership for assigned events, and stakeholder status reporting.

Contribute to research and development activities, including proposing improvements and new ideas and driving improvements into team practice/tools.

Work within a team of system testers to perform requirements verification on a large, multi‑node, Linux‑based satellite ground system with responsibility for end‑to‑end verification of assigned subsystems/capabilities.

Define and evolve testing strategies as the ground system is migrated to newer technologies, such as cloud computing and containerization, including how verification will be executed in containerized and/or cloud‑like environments.

Evaluate, recommend, and implement automated test strategies and tools by evaluating options, making recommendations, and implementing selected approaches.

Perform manual testing using formal test procedures and run automated tests on a…
