Lead Sealing Systems Engineer

Molex is seeking a Lead Sealing Systems Engineer to drive the design, development, and predictive engineering of sealing solutions for automotive connector systems. In this role, you will combine product design, materials science, and advanced simulation to develop robust sealing technologies that improve reliability, reduce validation cycles, and accelerate time to market.

As the technical lead for sealing systems, you will influence product architecture, establish engineering standards, and partner with global teams across product development, manufacturing, validation, and materials engineering to solve complex technical challenges and deliver innovative solutions.

We are looking for a self‑driven engineer who applies first‑principles thinking, thrives in a collaborative environment, and enjoys mentoring others. The ideal candidate combines strong technical expertise with the ability to influence decisions, build organizational capability, and create long‑term value through engineering excellence.

• Lead the design, development, and optimization of elastomer sealing solutions for connector systems.
• Define sealing system architecture, including seal geometry, groove design, tolerance analysis, and integration requirements.
• Develop and oversee advanced CAE methodologies to predict sealing performance, durability, environmental effects, and long‑term reliability.
• Establish and maintain sealing design standards, engineering guidelines, performance metrics, and validation methodologies.
• Own the sealing materials strategy, including material selection, characterization, qualification, and development of predictive material models.
• Lead simulation‑to‑test correlation and validation activities, leveraging data‑driven insights.
• Serve as the technical lead for sealing technologies, collaborating with product development, materials, manufacturing, validation, and quality teams.
• Mentor and develop global engineering resources, building organizational capability and promoting best practices in sealing design and CAE analysis.
• Drive continuous improvement, innovation, and technical standardization initiatives while identifying emerging technologies, materials, and industry trends.
• Establish strategic partnerships with suppliers, universities, and research organizations.

• Bachelor’s degree in Mechanical, Aerospace, or Materials Engineering.
• 5+ years of experience in product design and/or CAE simulation for elastomer sealing systems.
• 3+ years of experience in nonlinear FEA (large deformation, contact, material nonlinearity).
• 2+ years of experience in material modeling (hyperelastic, viscoelastic, temperature effects).
• Working knowledge of Design for Manufacturability, Design for Assembly, geometric tolerancing, and tolerance stack‑up analysis.

• Master's or Ph.D. in Mechanical Engineering, Materials Engineering, Polymer Engineering, or a related technical discipline.
• Experience with elastomer sealing systems, including silicone rubber materials, sealing performance, durability, environmental effects, and failure modes; automotive connector sealing experience is a plus.
• Advanced proficiency with nonlinear CAE tools such as Abaqus, ANSYS, or equivalent software, including large deformation, complex contact, and highly nonlinear simulations.
• Expertise in elastomer material characterization and modeling, including hyperelastic, viscoelastic, creep, relaxation, and temperature‑dependent behavior.
• Experience developing engineering standards, validation methodologies, and simulation‑to‑test correlation processes through collaboration with testing laboratories, validation teams, suppliers, and cross‑functional engineering partners.

• Medical, dental, vision insurance.
• Flexible spending and health savings accounts.
• Life insurance and disability coverage.
• Retirement plan.
• Paid vacation and time off.
• Educational assistance.
• Infertility assistance, paid parental leave, and adoption assistance (subject to eligibility).
