Job description

Job Description

Do you enjoy working in a dynamic lab environment and contributing to hardware that can directly impact the safety of service members and civilians? Shield AI is looking for a hands‑on Vibration Test Engineer to help validate the next generation of intelligent autonomous systems through rigorous dynamic testing.

The Mechanical Test team's mission is to inform and improve Shield AI hardware design by quantifying product performance through custom measurement systems, specialized testing, and rigorous analysis. As a Vibration Test Engineer, you will serve as the team's subject matter expert in vibration and structural dynamics, leading efforts to characterize hardware response, validate analytical models, and ensure products can withstand demanding operational environments.

We are looking for candidates who are passionate about structural dynamics, curious about how complex systems behave under dynamic loading, and excited to solve challenging engineering problems in a fast‑paced, collaborative environment.

Responsibilities

• Lead the planning, execution, and analysis of vibration test programs supporting product development, qualification, and flight readiness.
• Design, build, and deploy instrumented test setups for vibration, modal, structural, and environmental testing using industry‑standard measurement equipment.
• Execute shaker table testing including sine sweep, random vibration, sine‑on‑random, resonance search, dwell, and shock testing.
• Perform experimental modal analysis to characterize structural dynamics and validate finite element models.
• Develop fixture designs and test methodologies that accurately replicate operational loading conditions while minimizing fixture influence.
• Instrument hardware using accelerometers, strain gauges, force sensors, displacement sensors, and other dynamic measurement systems.
• Analyze vibration response data using frequency‑domain and time‑domain techniques to identify resonances, mode shapes, damping characteristics, and potential failure mechanisms.
• Partner closely with Mechanical Design and Structural Analysis engineers to correlate test results with analytical models and improve future designs.
• Investigate vibration‑related hardware issues, perform root cause analysis, and recommend design improvements.
• Develop comprehensive test plans, procedures, reports, and technical presentations that clearly communicate results and engineering recommendations.
• Maintain vibration testing equipment, data acquisition systems, instrumentation, and calibration records.
• Support environmental qualification testing and other mechanical test activities as needed.

Qualifications

• B.S. in Mechanical Engineering, Aerospace Engineering, Structural Engineering, or a related technical discipline.
• Hands‑on experience performing vibration testing of mechanical or aerospace systems through industry, research, internships, or competitive engineering projects.
• Experience operating electrodynamic shaker systems and associated vibration control software.
• Experience with accelerometers, signal conditioning, data acquisition systems, and dynamic instrumentation.
• Working knowledge of structural dynamics, vibration theory, modal analysis, and frequency response functions.
• Experience performing or supporting experimental modal testing and finite element model correlation.
• Familiarity with MIL-STD-810 vibration and shock testing or equivalent aerospace qualification standards.
• Experience interpreting vibration data and identifying resonances, structural response characteristics, and failure modes.
• Working knowledge of CAD software (NX preferred).
• Strong written and verbal communication skills with the ability to communicate technical findings to multidisciplinary teams.
• Demonstrated ability to take ownership of technical work, drive projects independently, and deliver high‑quality results in a fast‑paced engineering environment.
• Ability to obtain a Secret//Special Access Required (S//SAR) security clearance is desired.
• M.S. or Ph.D. in Mechanical Engineering, Aerospace Engineering, Structural Engineering, or a related technical field with an emphasis in structural dynamics or vibration.
• Experience designing vibration test fixtures and specialized dynamic test equipment.
• Experience using vibration control and data acquisition platforms such as Data Physics, Brüel & Kjær (HBK), Crystal Instruments, m+p International, LMS/Simcenter Testlab, or similar systems.
• Experience with finite element analysis software (ANSYS, Abaqus, Nastran, or equivalent) and test‑analysis correlation.
• Experience with strain gauge testing, digital image correlation (DIC), or other advanced structural measurement techniques.
• Experience supporting aerospace, defense, robotics, UAV, or other high‑reliability hardware development programs.
• Experience with Design of Experiments (DOE), root cause analysis, and failure investigation.
