• Ensure compliance with industry and military standards for mechanical test planning and reporting. 

QUALIFICATIONS 

• Bachelor's degree in mechanical, aerospace engineering, or related technical discipline. 

• Years of relevant experience in mechanical systems test engineering for aerospace, defense, or high-reliability systems in line with engineering level. 

• Knowledge of mechanical system test methodologies including acceptance, functional, and performance testing. 

• Experience performing mechanical system test campaigns and coordinating multidisciplinary teams. 

• Strong background in data analysis, systems engineering, and failure analysis for mechanical hardware. 

• Excellent communication, leadership, and technical documentation skills. 

• U.S. Citizenship required due to government contracts.  

PREFERRED SKILLS AND EXPERIENCE 

• Master's or higher degree in mechanical or aerospace engineering. 

• Expertise with data acquisition, test automation, and scripting (LabVIEW, Python, MATLAB) for mechanical test environments. 

• Hands-on experience with mechanical components including structures, mechanisms, actuators, deployables, and mechanical assemblies. 

• Familiarity with CAD tools, finite element analysis, and mechanical design principles. 

• Experience with test standards such as MIL-STD-810, NASA-STD-5018, or other aerospace mechanical test specifications. 

• Experience working in classified or secure test environments. 

• Active Secret or Top Secret clearance. 

COMPENSATION AND BENEFITS 

Base Salary: 

• Test Engineer 2:  $100,000-$120,000
• Test Engineer 3: $125,000-$155,000
• Senior Test Engineer: $140,000-$175,000

Equity + Benefits including Health, Dental, Vision, HRA/HSA options, PTO and paid holidays, 401K, Parental Leave 

Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, location, and experience. 

ADDITIONAL REQUIREMENTS
