This is an on-site role supporting the integration, verification, and validation of complex space systems. The selected candidate will lead and support system integration and test activities across the full product lifecycle, including requirements analysis for testability, test architecture development, integration planning, verification execution, anomaly resolution, and production support. This role is responsible for developing and executing test plans, procedures, and integration flows for spacecraft RF subsystems, lower-level assemblies, payload interfaces, and end-to-end Space Segment testing. Responsibilities also include coordinating integration activities for test beds, hardware/software-in-the-loop environments, and software simulators developed internally and by subcontractors. The Sr. Specialist will define and implement verification strategies, support requirements traceability and compliance, evaluate subsystem and system-level performance, and work cross-functionally to resolve technical issues discovered during integration and test. This position requires close collaboration with systems engineering, software engineering, mission, payload, quality, and operations teams, as well as external partners, to ensure technical readiness and successful execution of system-level integration and verification objectives. The ideal candidate will bring strong experience in complex system integration, spacecraft or aerospace test environments, and execution of structured verification and validation processes. Essential Functions: * Oversee the integration and testing of lower-level assemblies through subsystem and payload-level verification * Develop system test documentation, including Test Requirements Documents, Test Design Documents (TDDs), and test plans and procedures * Support and direct personnel in the execution of system testing and integration readiness activities for space payloads and/or space vehicles * Develop and execute functional, performance, and qualification test procedures, and document results to verify compliance with program requirements * Support test configuration setup, script development, test procedure development, implementation, checkout of test racks and test set software, and evaluation of analysis tools, as required * Identify, document, track, and help resolve test and integration issues through closure * Analyze test results, identify anomalies, and collaborate with development teams to determine root cause and support corrective actions * Represent SI&T in major technical reviews, including SRR, SDR, PDR, CDR, and TRR * Work extended and weekend hours, as needed, during critical SI&T phases of the program * Partner with cross-functional teams, including Systems Engineering, Project Engineering, and Software Engineering, during requirements analysis and verification planning, including development and maintenance of the Requirements Verification Traceability Matrix (RVTM) ## Related Videos - [Security Pitfalls for Software Engineers](https://www.wearedevelopers.com/videos/726-security-pitfalls-for-software-engineers) - [Coffee with Developers: David Heinemeier Hansson](https://www.wearedevelopers.com/videos/875-coffee-with-developers-david-heinemeier-hansson) - [Improving quality with Agentic AI with Rovo Dev and Xray](https://www.wearedevelopers.com/videos/2005-improving-quality-with-agentic-ai-with-rovo-dev-and-xray) - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [Coroutine explained yet again 60 years later](https://www.wearedevelopers.com/videos/690-coroutine-explained-yet-again-60-years-later) - [Collaboration Quantified: Lessons from Open Source Developer Networks](https://www.wearedevelopers.com/videos/1422-collaboration-quantified-lessons-from-open-source-developer-networks) ## Related Articles - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Should senior developers refuse interview coding challenges?](https://www.wearedevelopers.com/magazine/29-should-senior-developers-refuse-interview-coding-challenges) - [93 Java Interview Questions You Should Prepare For](https://www.wearedevelopers.com/magazine/14-93-java-interview-questions-you-should-prepare-for) - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers)
