Responsible for simulation and analysis of mechanical behaviors in drone systems focusing on vibration and thermal performance.
About the company
- Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces.
- Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected.
Responsibilities
- 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.
- 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.
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.
- We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
