What is a part time software tester?

Part time software testers are professionals who work limited hours, usually less than full-time, to evaluate and ensure the quality of software applications. They are responsible for identifying bugs, running test cases, and reporting issues to developers. This role is ideal for individuals who need flexible work arrangements or are gaining experience in the software industry. Part time software testers often collaborate with development teams to help improve the functionality and reliability of software products.

What does a part time software tester do?

As a part-time software tester, your job is to use a computer or another electronic device to test a piece of software and help troubleshoot any issues. In this role, you may discuss errors with programmers to help debug the software, document and report each issue you encounter, test recent fixes to verify whether or not they are working as intended, and occasionally provide your opinion on the overall status of the software. Part-time software testers often work from home or as part of a large team. Employers may list this job under names like QA tester or under industry-specific titles like video game tester.

What are the key skills and qualifications needed to thrive as a part time software tester, and why are they important?

To thrive as a Part Time Software Tester, you need a good understanding of software development concepts, attention to detail, and basic programming or scripting knowledge, often supported by a degree or coursework in computer science or a related field. Familiarity with test management tools (like Jira or TestRail), bug tracking systems, and automated testing frameworks is typically required. Strong analytical thinking, effective communication, and adaptability are essential soft skills to identify issues and collaborate with development teams. These skills are crucial for ensuring software quality, meeting project deadlines, and contributing to overall product reliability.

How do part time software testers typically coordinate their work with full-time development teams?

Part-time software testers often collaborate closely with full-time developers and QA teams by attending scheduled stand-ups, using project management tools, and maintaining clear communication through documentation and messaging platforms. Since their working hours may be limited, part-time testers are usually assigned specific test cases or modules and are expected to provide timely feedback on defects and usability issues. Flexibility and proactive communication are key to ensuring that their contributions align with sprint cycles and release timelines, and many organizations support this through well-defined testing processes and frequent check-ins.

Job Description:
We are seeking a Manager of Propulsion to lead fuel system development and integration for the X-BAT vehicle, powered by a fighter-class, afterburning jet engine. This role oversees the architecture, integration, testing, and operational support of flight-critical fuel systems operating across demanding thermal environments, aggressive maneuvering conditions, and mission-critical operating profiles.

You will lead engineers and technicians responsible for fuel tanks, fuel delivery systems, venting, pressurization, level sensing, and associated propulsion fluid systems. This role requires deep technical understanding, strong execution leadership, and close coordination across propulsion, flight test, manufacturing, and vehicle integration teams.

What you'll do:
  • Lead fuel system development activities from architecture through testing and flight operations.
  • Support and mentor fuel system REs responsible for fuel tanks, pumps, valves, vent systems, and associated propulsion hardware.
  • Drive system integration efforts considering elevated-G maneuvers, transient operation, vapor ingestion, cavitation, thermal effects, and fault tolerance.
  • Guide teams through fuel system thermodynamic and fluid dynamic trade studies involving heat soak, vapor pressure behavior, venting, and transient flow response.
  • Coordinate testing activities, instrumentation planning, and performance validation efforts.
  • Support failure investigations, root cause analysis, and design iteration activities.
  • Ensure schedules, technical execution, and supplier activities remain aligned with program goals.
  • Collaborate closely with propulsion, airframe, mission systems, and manufacturing teams.
Required qualifications:
  • Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, or related engineering discipline.
  • 7-10+ years of experience developing aerospace fuel or fluid systems.
  • Strong understanding of thermodynamics, fluid mechanics, heat transfer, and aerospace propulsion fundamentals.
  • Deep understanding of compressible and incompressible flow systems and aerospace fluid dynamics.
  • Experience with fuel system integration, testing, and operational support.
  • Experience leading engineering teams or major subsystem development activities.
  • U.S. Citizenship or ability to comply with ITAR requirements.
Preferred qualifications:
  • Experience with jet-powered UAVs, tactical aircraft, or aerospace fuel systems.
  • Familiarity with GFSSP, REFPROP, ANSYS, or fluid system modeling tools.
  • Experience with slosh dynamics, cavitation, vapor ingestion, venting, thermal management, and pressurization systems.
  • Background in rocket propulsion fluid systems.
  • Experience operating in test-driven aerospace development environments.
  • M.S. or Ph.D. in Aerospace Engineering or related discipline.
  • Ability to obtain a S//SAR level security clearance desired.
