About the Role

As a Physics Simulation Engineer, you will be responsible for the simulation and analysis of mechanical behaviors in our drone systems, with a focus on vibration and thermal performance. You will set up and validate advanced physics-based models to support robust and efficient drone design.

Responsibilities

• Structural & Modal Analysis: Perform Finite Element Analysis (FEA) to evaluate the dynamic behaviour and vibration modes of our systems.
• Vibration Mitigation: Design and simulate passive and active damping solutions to isolate sensitive optical payloads from motor and aerodynamic vibrations.
• Multi-Physics Simulation: Conduct thermal-mechanical simulations to assess the impact of heat dissipation on structural alignment, sensor calibration, and systems performances.
• Aerodynamic Modeling: Analyze the impact of wind loads and flight dynamics on the mechanical stability of the platform.
• Experimental Validation: Design and implement test benches for vibration and experimental modal analysis (using accelerometers, shakers, etc.) to correlate simulation models with real-world data.
• Optimization: Collaborate with the mechanical engineers team to optimize mass design and material selection for maximum rigidity-to-weight ratios.

Candidate Requirements

• Educational Background: MSc or PhD in Mechanical Engineering, Physics, Structural Dynamics, Vibration & Control.
• Technical Expertise:
  • Mastery of FEA tools like Simulia, Ansys, COMSOL, Abaqus…
  • Deep understanding of structural dynamics, modal analysis, and vibration theory.
  • Solid experience in test-simulation correlation (experimental modal analysis).
  • Ability to interpret simulation results critically, analyze experimental data and translate them into design insights.
  • Excellent command of mathematical tools related to vibration analysis (Fourier Transform, spectral analysis, etc…).
• Programming & Tools:
  • Proficiency in Python or MATLAB for data post-processing and simulation automation.
  • Familiarity with 3D CAD (CATIA, SolidWorks) and PLM environments.
• Industry Experience: 5+ years of experience in high-performance robotics, aerospace, or automotive NVH (Noise, Vibration, and Harshness). Experience with UAV airframes or gimbal systems is a major plus.
• Experimental Mindset: Familiarity with basic instrumentation and experimental techniques for validating simulations.
• Team Player: Collaborative mindset with the ability to work in cross-functional teams (design, systems, testing).
• Curiosity & Drive: Demonstrated initiative, problem-solving ability, and a desire to grow into technical leadership.
• Soft Skills: Ability to translate complex physics data into actionable design recommendations for the mechanical team.
• Commitment: 100% dedication to Harmattan AI’s mission and ambitious growth plans, ready to go the extra mile to ensure operational excellence.
