- Finite element analysis (FEA) and cost analysis to validate and optimize designs
- Presenting engineering design review materials to customers and leadership
- Collaborating with electrical engineers and cross-functional teams
You should have strong mechanical engineering fundamentals, excellent analytical and problem-solving skills, and the ability to communicate complex technical concepts clearly in writing and verbally.
REQUIREMENTS:
- Bachelor of Science in Mechanical Engineering (or related field) with minimum 2–5 years of industry experience in design and analysis, OR Master of Science with 0–3 years of industry experience
- Strong understanding of mechanical engineering principles
- Strong analytical, troubleshooting, and problem-solving skills
- Proficiency with CAD tools (SolidWorks, CATIA, Creo, or AutoCAD)
- Practical understanding of DFM/DFMA implications of material and process selection
- Knowledge of GD&T, drafting standards, and engineering documentation practices
- Experience with engineering analysis tools (ANSYS, MATLAB, or similar)
- Experience with CNC manufacturing
- Excellent written and verbal communication skills
- U.S. citizenship or eligible immigration status (required by U.S. Government Space Technology Export Regulations)
PREFERRED EXPERIENCE:
- Familiarity with electronics assemblies and experience working closely with electrical engineers
- Aerospace industry design, development, qualification, and manufacturing processes
- Electronics packaging experience including thermal, vibration, and stress dynamics, or spacecraft structures and mechanisms
- EMI/EMC mitigation techniques
