• Integrate existing Test Program Sets (TPS) into new development environments, ensuring functionality and compatibility.
• Develop and modify test software applications using LabVIEW and C# (or similar object-oriented languages) for automated testing systems.
• Perform software debugging and troubleshooting in lab environments with test equipment and Units Under Test (UUT).
• Conduct integration testing between legacy hardware systems and new software platforms.
• Implement minor hardware modifications as needed to support software integration efforts.
• Work hands-on in the lab environment to validate test program functionality and identify software-related issues.
• Collaborate with systems engineers and customers regarding integration efforts and software development progress.
• Document software designs, integration procedures, and test results.
• Support requirements verification and validation through software testing.

Qualifications:
Required:

• Bachelor's Degree in Software Engineering, Computer Engineering, Systems Engineering, or related technical degree.
• 5 or more years of professional software development experience in testing, automation, or related roles.
• Proficient experience with LabVIEW programming and development (National Instruments ecosystem).
• Demonstrated professional experience with C# or similar object-oriented programming languages (Java, C++).

• Ability to work hands-on in lab environments with test equipment and hardware systems.
• Strong problem-solving skills with focus on software-level debugging.
• Willing and able to travel up to 20%
• Willing and able to obtain a DoD security clearance

Desired:

• Experience with National Instruments products: TestStand, CVI, PXI systems, or related test platforms.
• Knowledge of Python, ANSI-C, or other scripting languages.
• Ability to read electrical schematics and understand basic circuit functionality.
• Familiarity with electrical test equipment: digital multi-meters, oscilloscopes, power supplies, signal generators.
• Experience with Test Program Set (TPS) or Automated Test Equipment (ATE) development for aerospace/defense applications.
• Understanding of MIL-PRF-28800, MIL-STD-810, MIL-STD-461 standards.
• Experience migrating legacy test systems to modern platforms.
• Knowledge of US Air Force and/or Navy aviation maintenance organizational structure.
• Version control systems (Git, SVN) and software development lifecycle practices.
