What is a part time test engineer?

Part Time Test Engineers are professionals who work fewer hours than full-time employees to test software, hardware, or systems for quality and functionality. Their responsibilities typically include designing test cases, executing tests, identifying bugs, and reporting issues to the development team. Part-time positions offer flexibility, making them suitable for students, parents, or those seeking work-life balance. These engineers play a critical role in ensuring products meet quality standards before release, even on a reduced schedule.

What are the key skills and qualifications needed to thrive as a part time test engineer?

A Part Time Test Engineer needs a solid background in software testing principles, familiarity with quality assurance methodologies, and a relevant technical degree or equivalent experience. Proficiency in test automation tools (such as Selenium or JUnit), bug tracking systems, and version control software is typically required. Strong attention to detail, effective communication, and time management are crucial soft skills for excelling in this flexible role. These competencies ensure efficient identification and resolution of software issues, contributing to reliable product releases even within limited working hours.

What are some common challenges faced by part time test engineers, and how can they be addressed?

Part-time Test Engineers often face challenges related to time management and communication, as they may not be present during all project meetings or development cycles. To address these issues, it’s important to maintain clear documentation and regular updates with the team, ensuring that testing priorities and results are communicated effectively. Leveraging collaborative tools and maintaining flexibility can help balance workload and ensure that quality standards are met despite limited hours. Building strong relationships with full-time colleagues can also help streamline handoffs and clarify expectations.

What is the difference between Part Time Test Engineer vs Part Time QA Tester?

AspectPart Time Test EngineerPart Time QA Tester
CredentialsTypically requires a degree in computer science or related field, certifications like ISTQB are commonOften requires similar certifications and a background in software testing
Work EnvironmentWorks in software development teams, involved in designing and executing testsPerforms testing tasks, often in a similar environment, focusing on executing test cases
Industry UsageUsed across software, gaming, and tech industries for quality assurance rolesCommonly used in software development and IT sectors for testing roles

Both roles involve testing software to ensure quality, with overlapping skills and environments. The main difference lies in the scope: Test Engineers often design testing processes, while QA Testers focus on executing tests. Both roles are essential in software development and frequently searched together by employers and job seekers.

Job Description:

We are seeking a Senior Propulsion Test Engineer to lead the planning and execution of propulsion test campaigns for the X-BAT platform. This role is responsible for end-to-end ownership of propulsion test activities—from test architecture and test stand design through execution, data analysis, and iteration - supporting a low-bypass turbofan-powered Group 5 UAV.

You will serve as the focal point for propulsion testing, ensuring test results accurately characterize engine and subsystem performance, de-risk integration, and inform flight readiness decisions. This role is hands-on, data-driven, and highly cross-functional - requiring close collaboration with propulsion engineers, design engineers, technicians, controls, airframe, and flight test teams.

What you will do in this role:
  • Own the propulsion test program from requirements through execution, data review, and test-to-flight handoff.
  • Architect, design, analyze, and build test stands and fixtures for engine, fuel, oil, bleed air, and TVC-related testing.
  • Define and implement instrumentation plans, DAQ architecture, calibration methods, and test procedures.
  • Lead ground test campaigns, including performance mapping, transient response, and edge-of-envelope testing.
  • Analyze test data to validate performance, identify anomalies, and drive design or control updates.
  • Partner with propulsion REs and controls engineers to ensure test coverage closes risk against CONOPS and mission profiles.
  • Drive root cause investigations for test anomalies and implement corrective actions.
  • Author test plans, reports, and readiness reviews; represent propulsion test in design and flight readiness reviews.
Required qualifications:
  • Bachelor’s degree in Aerospace Engineering or a related engineering discipline.
  • 5+ years of experience in propulsion or engine testing in aerospace development environments.
  • Hands-on experience with engine test cells, test stand design, instrumentation, and DAQ systems.
  • Strong understanding of gas turbine engine performance, transients, and test methodologies.
  • Proficiency in Python (or similar) for data reduction, automation, and analysis workflows.
  • Experience supporting flight test readiness and test-to-flight transitions.
  • U.S. Citizenship or ability to comply with ITAR requirements.
  • Ability to obtain a S//SAR level security clearance desired.
Preferred qualifications:
  • Experience testing low-bypass turbofan engines or propulsion subsystems on UAVs or tactical aircraft.
  • Familiarity with REFPROP, GFSSP, ANSYS, or FEA to support test interpretation and correlation.
  • Experience designing structural test fixtures, load paths, thermal management, and safety systems for hot-fire environments.
  • Background in controls integration, actuator testing (e.g., TVC), and transient characterization.
  • Experience operating in a test-driven, hardware-centric aerospace development environment.
  • M.S. in Aerospace Engineering or a related discipline.
