Job Description
This isn’t just a “mechanical” job; it’s a Thermal and High-Speed Data role. Molex’s BiPass technology is a game-changer for data centers, allowing signals to “bypass” the lossy PCB. You will be designing the cooling systems and mechanical housings that keep the world’s most powerful AI servers from overheating. You are essentially the architect of the physical infrastructure that powers the modern internet.
Requirements
- Education: Bachelor of Engineering in Mechanical.
- Experience: 3 to 5 years in product design, including exposure to testing systems and manufacturing processes.
- Technical Skillset: Proficiency in Siemens NX for 3D modeling and 2D drafting.
- Domain Knowledge: Understanding of electromechanical components and fabrication methods (molding, sheet metal, etc.).
- Standards: Strong grasp of Geometric Dimensioning & Tolerancing (GD&T) and the Product Development Process (PDP).
- Preferred Qualifications:
- Deep expertise in Teamcenter and PLM/PDM systems.
- Prior experience in the connector or electromechanical industry.
- Ability to assess solution alternatives and mitigate design risks independently.
Roles and Responsibilities
- Advanced CAD Modeling: Use Siemens NX to develop precision 3D models and assemblies of mechanical systems, translating customer requirements into detailed designs.
- Documentation & PLM: Manage the complete product lifecycle within Teamcenter, including the creation of Bills of Materials (BOMs), Engineering Change Orders (ECOs), and release packages.
- Design Validation: Perform rigorous tolerance analysis and feasibility studies to ensure fit, form, and function while mitigating design risks.
- Manufacturing Synergy: Collaborate with production teams to resolve manufacturing discrepancies and optimize designs for efficient fabrication (molding, sheet metal, and assembly).
- Technical Leadership: Participate in cross-functional design reviews, providing technical insights to improve product integrity and performance.

Company Culture & Insights
Molex is a subsidiary of Koch Industries, which operates under a unique philosophy called Market-Based Management (MBM).
Global Hub: The Bangalore team is a critical pillar of Molex’s global engineering strategy, meaning your designs will be used by tech giants worldwide.
Entrepreneurial Spirit: You are encouraged to act like an owner—challenge the status quo and find better ways to create value.
Reward for Contribution: Compensation is based on the value you create, not just your tenure or job title.
Why We Recommend This Job
- AI & Data Center Boom: Liquid cooling and BiPass cables are two of the fastest-growing sectors in tech right now due to the massive cooling demands of AI chips (like NVIDIA’s H100/B200).
- Premier Toolstack: Mastery of Siemens NX and Teamcenter puts you in the top tier of mechanical designers globally. These tools are the industry standard for complex aerospace and automotive engineering.
- Holistic Engineering: You handle the “Big Three” of mechanical design: Thermal management, Structural integrity, and High-volume manufacturing.
Career Growth Potential
At Molex, the path typically leads to Senior Design Engineer or Lead Systems Architect. Because you are working on liquid cooling, you could also pivot into Thermal Engineering or Data Center Infrastructure Management. The Koch network is vast—success here could open doors to other Koch companies in energy, chemicals, or electronics.
Skills You’ll Gain
- Advanced GD&T: Moving from basic dimensions to complex tolerance stack-up for high-precision connectors.
- PLM Mastery: Deep-diving into Teamcenter processes for global data integrity.
- Thermal Design: Learning the nuances of heat sink efficiency and liquid cooling manifolds.
Salary & Benefits Info
- Estimated Salary: For 3–5 years of experience in Bangalore’s electromechanical sector, the Total Compensation (TC) typically ranges from ₹12,00,000 to ₹19,00,000 per annum.
- Benefits: Molex (Koch) is known for its “Total Rewards” philosophy, which includes performance-based bonuses, comprehensive health insurance, and significant investment in professional upskilling.
Frequently Asked Interview Questions
Technical Questions (Physical Design & Low Power)
- NX Proficiency: “How do you use ‘Top-Down Design’ methodology in Siemens NX to manage large assemblies like a server rack?”
- GD&T: “Explain the difference between ‘Maximum Material Condition’ (MMC) and ‘Regardless of Feature Size’ (RFS). When would you use a ‘Bonus Tolerance’?”
- Thermal Management: “What are the mechanical considerations for a liquid cooling loop to prevent leakage in a high-voltage environment?”
- Manufacturing: “If a sheet metal part is failing at a bend, what design modifications would you suggest without changing the material?”
Behavioral & Culture Questions
- Entrepreneurial Mindset: “Tell me about a time you challenged a standard process to create a more efficient design. What was the outcome?”
- Value Creation: “How do you prioritize design features when there is a conflict between performance requirements and manufacturing costs?”
- Collaboration: “Describe a time you had to interpret ‘Voice of Customer’ (VOC) data that was vague or contradictory. How did you proceed?”
