Simulation / Mechanical Analysis Engineer (Aerospace)

Location: Lausanne, Switzerland; on-site

Company

hirify.global is a next-generation defense prime developing autonomous and scalable defense systems for allied forces.

What you will do

• Analyse and optimise carbon chassis for stiffness, mass, resonance, and performance consistency across quadcopter platforms.
• Perform modal, harmonic, random vibration, static, stiffness, fatigue, crash, shock, and impact simulations for composite, plastic, and aluminium structures.
• Model laminated and pultruded carbon structures, including ply orientation, anisotropy, bonded and bolted joints, damage, delamination, and failure behaviour.
• Define validation tests using modal testing, accelerometers, shakers, drop and impact tests, and flight data; correlate simulations with measurements.
• Translate analysis results into geometry, stiffener, material, and joint changes, implementing recommendations in CAD and iterating with design owners.
• Develop reusable scripts, templates, calculation sheets, and documented methodologies so the team can perform reliable first-order analyses autonomously.

Requirements

• Master’s degree in Mechanical Engineering, Aerospace Engineering, Structural Mechanics, or a related field.
• Proven FEA experience with modal, vibration, and dynamic analysis using tools such as Ansys, Abaqus, Nastran, OptiStruct, or COMSOL.
• Experience with explicit crash, shock, and impact simulations using tools such as Ansys LS-DYNA, Abaqus/Explicit, or Radioss.
• Strong knowledge of carbon-fibre composites, anisotropy, layups, joints, and damage, delamination, and failure criteria.
• Ability to correlate simulations with physical testing and critically assess model validity.
• Working CAD proficiency, preferably SolidWorks, plus scripting or automation skills in Python, MATLAB, or APDL.

Culture & Benefits

• Work on mission-critical autonomous defense systems with real-world impact.
• Operate in a demanding environment focused on rigor, ownership, excellence, and execution.
• Collaborate with design, electronics, and industrialisation teams.
• Maintain clear technical documentation as a source of truth for the simulation methodology.
