Software Test Automation Engineer

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.

• 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

• Bachelor’s degree in Aerospace Engineering, Computer Science, Software Engineering, or related field

• 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
