Job Summary

We are seeking a Design Engineer (R&D;) with 25 years of experience in mechanical product / sub system design and development. The ideal candidate will be responsible for conceptualizing, designing, and developing new products, with a strong focus on power transmission systems, casting and sheet metal components, and engineering calculations. The candidate should possess hands-on experience in Siemens NX (Mandatory) and be capable of driving product development from concept to production.

Key Responsibilities

1. Concept Design

- Own module/subsystem definition aligned with overall machine architecture and functional requirements.
- Generate and evaluate multiple design concepts considering performance, cost, manufacturability, and reliability.
- Develop concepts for mechanical systems including power transmission (gears, gearboxes, shafts, drive systems).
- Perform preliminary engineering calculations (power, torque, load estimations) to validate feasibility.
- Select suitable materials and mechanisms based on application requirements.
- Collaborate with cross-functional teams (R&D;, manufacturing, sourcing) during concept evaluation.
- Participate in design reviews to finalize optimal concepts.

2. Detailed Design

- Develop detailed 3D models, manufacturing drawings, and BOMs.
- Design casting and sheet metal components with focus on manufacturability and cost optimization.
- Perform detailed engineering calculations including static and dynamic load analysis.
- Apply GD&T; principles and perform tolerance stack-up analysis for assemblies.
- Ensure proper subsystem integration within the overall machine architecture.
- Drive design reviews and incorporate feedback from cross-functional teams.




- Develop and maintain engineering standards, design guidelines, and documentation.
- Support value engineering and continuous design improvements.

3. Prototyping & Testing

- Support prototype development, assembly, and initial build validation.
- Conduct design validation, functional testing, and reliability studies.
- Analyze test results and refine designs to meet performance requirements.
- Perform failure analysis and root cause analysis (8D, 5 Why, Fishbone) for design issues.
- Drive corrective actions and design improvements based on validation outcomes.
- Support production ramp-up and resolve engineering issues during manufacturing.
- Contribute to lifecycle management including upgrades, modifications, and field issue resolution.
- Mentor junior engineers and support knowledge-sharing initiatives.
