Mechanical Design Engineer

Mechanical Design Engineer – Power Electronics Packaging (Defence Systems)

Location: Hyderabad

Department: Engineering / R&D

Experience: 3–6 years

Employment Type: Full-time

About the Role

We are looking for an experienced Mechanical Design Engineer to join our Power Electronics team

developing ruggedized DC-DC converters, inverters, and power electronic systems for defence

applications. The ideal candidate will have hands-on experience in thermal design, heat sink

development, 3D modelling, and mechanical packaging for high-reliability systems operating in

demanding environments.

Key Responsibilities

• Design and develop mechanical enclosures and packaging for DC-DC converters and

water-cooled inverters.

• Engineer thermal management systems including heat sinks, liquid cooling, and airflow

optimization.

• Create and maintain 3D models, mechanical assemblies, and detailed manufacturing

drawings using CAD tools such as SolidWorks, Creo, or CATIA.

• Design panels, brackets, and ruggedized mechanical structures compliant with defence

and MIL standards.

• Perform thermal and structural simulations (CFD/FEA) to validate mechanical integrity

and reliability.

• Collaborate with electrical, thermal, and systems engineers to ensure integrated system

performance.

• Support prototype development, testing, and qualification of mechanical assemblies.

• Ensure compliance with MIL-STD-810, MIL-STD-461, and other applicable defence

environmental and mechanical standards.

Qualifications & Skills

• Bachelor’s / Master’s Degree in Mechanical Engineering or a related discipline.

• 3–6 years of experience in mechanical design of power electronics systems or

defence/aerospace equipment.

Proficiency in 3D CAD tools (SolidWorks, Creo, or CATIA).

• Strong knowledge of thermal design, heat sink development, and liquid cooling systems.

• Understanding of manufacturing processes – sheet metal, die-casting, machining, and

coatings.

• Experience in FEA/CFD analysis for thermal and structural validation.

• Knowledge of DFMEA, DFM, and DFA principles.

• Excellent communication, teamwork, and documentation skills.

Preferred Qualifications

• Experience with defence-grade mechanical design and environmental qualification.

• Familiarity with EMI/EMC mechanical mitigation and IP-rated enclosures.

• Exposure to lightweight materials, corrosion protection, and ruggedization techniques.

• Knowledge of reliability engineering and system integration for defence power systems.
