Senior Mechanical Engineer - Data Center

Hitachi Energy is shaping the future of data center infrastructure, and they are seeking a Senior Mechanical Engineer to design and optimize mechanical systems for advanced digital environments. The role involves leading mechanical design for transformers, collaborating with global teams, and ensuring compliance with regulations while driving innovation in mechanical design and cooling technologies.

Responsibilities:

• Lead the mechanical design and optimization of transformers built for high‑power‑density data center environments
• Develop cooling concepts and validate thermal performance for forced‑air, oil‑natural, oil‑forced, and hybrid systems
• Perform mechanical and thermal analyses, including stress, pressure drop, and serviceability evaluations
• Collaborate with global engineering teams to integrate mechanical systems into complete transformer and substation solutions
• Participate in customer design reviews and present mechanical concepts and trade‑offs
• Support issue resolution throughout design, manufacturing, testing, installation, and operation
• Drive standardization, modularity, and innovation in mechanical design, materials, and cooling technologies
• Contribute to tender reviews, vendor evaluations, and project execution
• Responsible to ensure compliance with applicable external and internal regulations, procedures, and guidelines

Requirements:

• Bachelor's degree in Mechanical Engineering or related discipline; Master's preferred
• 10+ years of mechanical engineering experience, ideally with power transformers or data center applications
• Expertise in transformer mechanical systems such as tanks, radiators, piping, and thermal/cooling components
• Proficiency in 3D CAD tools (e.g., CREO or equivalent)
• Strong knowledge of IEEE/IEC transformer standards and customer‑driven requirements
• Experience working within global, cross‑functional engineering environments
