We're seeking a passionate Mechanical FEA Engineer & Mechanical Design Support (m/f/d) to join our engineering team and support the structural performance of cutting-edge unmanned ground vehicles (UGVs). In this role, you’ll be a key contributor in driving mechanical design decisions through advanced structural analysis and simulation. You will also collaborate closely with the mechanical design team, contributing hands-on to CAD modeling and design implementation to bring high-performance vehicle components from concept to reality.

If you're excited to apply your mechanical simulation expertise in a fast-paced, collaborative, and innovation-driven environment, we invite you to bring your talent and join us.

To join our team, you should be excited to

• Competitive salary and benefits package
• A shaping role in an emerging dual use company
• Own structural analysis for chassis, suspension, enclosures, brackets, payload mounts, and other components under off-road duty cycles
• Define loads, boundary conditions, and material models; develop and correlate simulation results with physical tests where possible
• Run static, modal, and fatigue assessments; propose design changes and validate improvements
• Create simplified models and scalable workflows once an FEA toolchain is selected
• Collaborate with the mechanical design team to implement changes in Autodesk Inventor and manage data in Vault
• Document assumptions, safety factors, and margins; lead and contribute to design reviews focused on structural performance
• Support prototype testing; instrument parts/assemblies and reconcile simulation results with real-world measurements
• Contribute to mechanical design work during low-analysis periods (hands-on CAD modeling and detailing)
  
  

• Proficient in structural FEA, including linear static, buckling, modal, and basic fatigue analysis
• Skilled in load case derivation for off-road vehicles or unmanned ground vehicles (UGVs)
• Strong understanding of materials such as aluminum, steels, and composites, including joints, welds, and bolted interfaces
• Experience with FEA tools such as Ansys, Abaqus, or Nastran is highly desirable
• Ability to script repeatable analysis reports using Python or MATLAB
• Hands-on experience with Autodesk Inventor (CAD) and Vault (PDM), or similar CAD/PDM systems
• Strong team player who thrives in a fast-paced, collaborative startup and problem-solving environment
• Self-driven, able to take ownership of tasks and solve real-world engineering challenges independently
• Excellent communication skills in English, both written and spoken

• Competitive salary and benefits package
• A shaping role in an emerging dual use company
• Opportunity to work with a highly innovative, international, and dynamic team
• Room for professional growth and development
• Participation in the company's success, with access to regular events, knowledge exchange and meetups
