Physics Simulation Engineer

About US

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.

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.

• We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
