We’re looking for a passionate candidate with an Aerospace and Software background to expand our Simulation, Integration, and Test (SIT) team. The SIT department plays a pivotal role in ensuring the successful deployment and operation of satellites by providing support to critical areas: Flight Software, Ground Software, Vehicle Test, and Mission Operations. The department collaborates with engineering teams to develop and maintain modern software engineering solutions that lead to mission success. Additionally, it employs rigorous testing processes to validate hardware and software, minimizing risks prior to launch. On the ground, the department supports the seamless operation of ground software systems for satellite communication, monitoring, and control, facilitating real-time data analysis and mission management. Together, these efforts ensure that satellites are properly launched, placed into orbit, and operated efficiently, supporting a range of applications for our customers.  The ideal candidate will act as a critical interface between developers and internal customers, working across engineering teams to integrate and test mission-critical software. They will identify and isolate failures across software, test, infrastructure, and configuration boundaries, then communicate clear, actionable findings to the appropriate stakeholders. Success in this role also requires improving the reliability, repeatability, and automation of regression testing while providing accurate test status and risk information to support release decisions.  Responsibilities  Plan, coordinate, and execute software integration, regression, and release testing for flight software, ground software, interface middleware, and other SIT products.  Translate high-level designs, use cases, and requirements into high-quality test scripts  Interact with other York departments to support testing using SIT products  Support test-like-you-fly, test-driven development for spacecraft flight software, ground software, and space vehicle integration  Write and execute test plan documents and use cases with collaboration from other York developers  Perform troubleshooting and debugging of SIT tests and infrastructure  Develop and maintain automated integration tests for ground software and flight software CI/CD pipelines  Diagnose and triage test failures, pipeline failures, environmental issues, and software defects  Identify opportunities to improve test effectiveness, execution efficiency, reliability, observability, and automation coverage  Follow coding contribution standards and agile development practices  Create documentation and user guides  Communicate complex topics to both technical and non-technical audiences  Required Qualifications  Bachelor’s degree in Aerospace Engineering, Computer Science, Software Engineering, or related field  2+ Years of experience in Software Engineering, Software Testing, Software Systems Engineering, or related field  Demonstrated proficiency with Python  Experience troubleshooting software behavior across multiple applications, services, interfaces, or system components  Demonstrated proficiency with Git and modern Agile software development practices   Experience working in Linux environments  Demonstrated proficiency with bash/shell scripting  Familiarity with CI/CD concepts and using or supporting automated build, integration, or test pipelines  Experience with writing test documentation, such as test plans, procedures, reports, and defect records  Capable of managing multiple tasks while delivering according to program milestones and release commitments  Can proactively identify problems and communicate them clearly to leadership  Proficient at technical documentation  Self-starter with the ability to pick up new concepts quickly  Desired Qualifications  Experience with Docker, Docker Compose, & or any containerized environments  Experience with frontend automation software such as Cypress, Playwright, Selenium, etc.  Experience with REST APIs, message-based interfaces, and network protocols   Experience with Software in the loop test systems  Experience with Hardware in the loop test systems  Experience in testing and validation of satellite subsystems  Experience with data analysis and reporting  Experience with test management, requirements management, and defect-tracking tools  Experience with UI/UX testing   Experience with relational or time-series databases (SQL, InfluxDB, MongoDB)  Experience with C#  Experience with embedded development   Active Top Secret security clearance or ability to obtain
