Senior Test Engineer

About the Role 

Whisper Aero is seeking a highly skilled and experienced Senior Test Engineer to support the development and testing of our cutting-edge electric propulsors. This role involves designing and executing experiments, building ground test rigs, implementing instrumentation systems, and analyzing data to drive innovation. The ideal candidate will have a strong background in aerospace instrumentation, electronics, and software tools for automation and analysis, with the ability to tackle complex challenges and deliver meaningful insights.

What You’ll Do

• Develop and implement test plans, design efficient experiments, and perform specific tests such as static strain, modal analysis, radiated sound power, and propulsor characterization.
• Select, implement, and troubleshoot instrumentation (e.g., strain gauges, load cells, accelerometers, microphones, etc.) and use data acquisition systems like PAK to collect and process test data.
• Design and build test rigs for load measurement, aerodynamics, and other performance evaluations.
• Post-process large datasets, reduce data, and perform statistical analysis using tools like MATLAB and Python.
• Work closely with cross-functional teams to integrate designs and frameworks and lead test readiness reviews.
• Mentor junior engineers and be mentored by senior team members.

Basic Qualifications

• Expertise in aerospace instrumentation and electronics, including amplifiers, signal conditioners, strain gauges, load cells, and more.
• Functional understanding of high-power electrical systems and machine characterization
• Proficiency in DAQ software (e.g., HBK, Dewesoft, LabVIEW), programming (Python, MATLAB, microcontrollers), and CAD
• Experience with experiment design, statistical analysis, and data organization
• Strong analytical and communication skills
• Willingness to work on tasks beyond core responsibilities
• U.S. Person status

Bonus Qualifications

• Expertise in acoustics, aeroacoustics, aerodynamics, and propulsion
• Experience with low-speed wind tunnel testing and advanced instrumentation (e.g., laser vibrometers, Blade Tip Timing measurement)
• Skills in designing electronic assemblies and printed circuit boards
• Familiarity with rapid prototyping and 3D printing
• Experience with drones, model aircraft, or a private/remote pilot certificate
• Passion for aviation and innovation
