Mechanical Design Engineer 1

Position Overview

Rubbercraft is seeking a Mechanical Design Engineer to support the design, development, and testing of elastomeric components and precision mechanical systems. Ideal for engineers passionate about mechanical design, materials science, and advanced manufacturing, this entry-level role contributes to custom-engineered solutions for high-performance aerospace, defense, space, energy, and industrial applications. Rubbercraft, with over a century of expertise, designs innovative solutions such as aerodynamic seals, fireproof seals, inflatable canopy seals, and more.

Key Responsibilities

• Design and develop custom elastomeric components, seals, and polymer-based solutions for aerospace and defense applications.
• Create 3D CAD models, technical drawings, and engineering documentation using SolidWorks and/or CATIA in 3DX PLM (ENOVIA).
• Design, test, and validate fixtures using 3D printing technology.
• Conduct FEA analysis for elastomers and composite nonlinear analysis.
• Optimize designs for manufacturability, durability, and cost-efficiency for extreme environments.
• Develop and elaborate engineering documentation, quality test proposals, and compliance reports (FAA, AS9100, ISO 9001, MIL-SPEC).
• Collaborate with cross-functional teams (manufacturing, quality, lab) to transition designs from concept to production.
• Support prototype development, validation testing, troubleshooting, and technical specification refinement.
• Research and integrate new elastomeric material data and manufacturing techniques to enhance product performance.
• Contribute to lean engineering initiatives and continuous improvement projects.

Required Qualifications

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related field.
• 2 to 3 years of experience in mechanical design, elastomeric components, or aerospace/defense manufacturing.
• Proficiency in 3D CAD software (SolidWorks and/or CATIA).
• Strong understanding of GD&T and ASME Y14.5 standards.
• Familiarity with manufacturing processes such as 3D printing, rubber molding, polymer extrusion, CNC machining, and coatings applications.
• Excellent problem-solving abilities and effective verbal and written communication skills.

Preferred Qualifications

• Knowledge of FAA, AS9100, MIL-SPEC, and ITAR regulations.
• Experience with FEA (Finite Element Analysis) using Abaqus and stress analysis in materials science (elastomers, polymers, composites, metals).
• Background working with aerospace OEMs, defense contractors, or high-performance industrial manufacturers.
• Experience in seal design, EMI shielding, or high-temperature polymer applications.
• Familiarity with 3DX or any other PLM systems.

Benefits & Perks

• Comprehensive medical, dental, and vision coverage
• Short and long-term disability coverage and accident insurance
• Critical illness, basic and supplemental life insurance
• Employee assistance plan, retirement savings with matching, and developmental opportunities

Rubbercraft is an Equal Opportunity Employer (Veterans/Disabled - Affirmative Action Employer). This position requires ITAR compliance; all applicants must be U.S. persons as defined by ITAR.
