Job summary

Apex Technology, Inc. seeks a Spacecraft Dynamics Engineer to own dynamic analysis and vehicle response for our satellite buses.

You will predict and validate hardware behavior across ground, launch, and on-orbit phases, working with structures, test, and systems teams to ensure robustness against vibration, shock, and acoustics. The role requires extensive experience in structural dynamics, loads derivation, and FEM analysis, plus the ability to build tools for simulation and data processing.

Qualifications

• Bachelor’s degree in mechanical, aerospace, or related engineering field.
• 8+ years of experience in structural dynamics, loads, or environment prediction.
• Strong fundamentals in vibration, shock, transient response, and frequency-domain analysis.
• Experience with finite element modeling and analysis (NASTRAN, FEMAP, or similar).
• Experience developing simulation tools and processing telemetry or flight data.

Responsibilities

• Own dynamic and loads analysis across components, subsystems, and full spacecraft.
• Expertise in CLA, load derivation and structural verification.
• Develop load cases and environmental requirements (quasi-static, random vibration, shock, acoustics).
• Predict vehicle response across launch, deployment, and on-orbit conditions.
• Perform structural dynamics analyses using FEM and analytical methods to evaluate loads, margins, and system behavior.
• Build and assemble coupled system models across spacecraft and launch vehicle interfaces.
• Plan and execute dynamic test campaigns, including vibration and mode survey testing, from setup through data validation and model correlation.
• Process and analyze test and flight data to validate models and improve prediction accuracy.
• Evaluate analytical predictions against test and flight data and drive improvements to loads methodologies.
• Develop internal tools and workflows (Python, MATLAB, or similar) for simulation, data processing, and signal analysis.
• Partner cross functionally with design, test, and manufacturing teams to influence hardware and ensure requirements are met.
• Provide technical leadership on complex dynamics problems and mentor more junior engineers.
