careers-nikkiso is hiring a Mechanical Design Engineer

About the Role

Role Overview

As a Mechanical Design Engineer, you will take ownership of the mechanical design and integration of maritime skid-mounted systems. Your work will span the entire product lifecycle—from initial concept and 3D modeling to prototype testing, certification, and post-deployment optimization. You'll ensure designs meet operational, environmental, and manufacturing requirements specific to marine applications.

Key Responsibilities

  • Develop complete mechanical architectures for skid-mounted maritime systems, including layout of core components, transmission mechanisms, hydraulic and pneumatic circuits, thermal management, and fluid delivery networks.
  • Create detailed 3D models in SolidWorks and produce production-ready 2D engineering drawings using AutoCAD, accompanied by comprehensive bills of materials.
  • Ensure mechanical designs are fully compatible with electrical and control systems, while optimizing spatial arrangements for onboard installation and serviceability.
  • Refine structural parameters such as impeller geometry, pipeline sizing, and sealing techniques to improve efficiency, reliability, and durability under continuous operation.
  • Address challenges in fluid dynamics and thermal performance, including pressure drop, heat dissipation, and leakage prevention.
  • Support prototype build, commissioning, and performance validation through load testing, efficiency measurement, and simulated marine environment trials.
  • Analyze test results to refine designs and verify compliance with pressure ratings, noise levels, and energy consumption targets.
  • Design for marine-specific conditions by selecting corrosion-resistant materials, improving vibration damping, and enhancing sealing systems against seawater ingress.
  • Ensure all designs adhere to international maritime standards (e.g., ABS, DNV, LR) and support certification processes with classification societies.
  • Collaborate with production teams to optimize designs for manufacturability, focusing on welding methods, modular assembly, and anti-corrosion treatments.
  • Define precision requirements, assembly sequences, and surface treatments to reduce costs and improve throughput.
  • Work with structural engineers to strengthen skid bases and equipment mounting systems.
  • Review electrical routing for mechanical feasibility and support procurement in evaluating and selecting critical components.
  • Provide technical guidance during manufacturing and resolve issues related to fit, function, and process adjustments.
  • Develop and maintain technical documentation such as design specifications, assembly instructions, maintenance manuals, and troubleshooting guides.
  • Coordinate with third-party labs to complete product certification testing.
  • Engage with customer engineering teams to clarify requirements and offer technical recommendations.
  • Monitor field performance data, diagnose mechanical failures, and lead iterative improvements to prevent recurrence.

Qualifications

  • Bachelor’s degree or higher in Mechanical Engineering, Mechanical Design, Manufacturing and Automation, Naval Architecture, Ocean Engineering, or a related field.
  • 3–5 years of hands-on experience in mechanical design for maritime equipment, offshore systems, or large-scale skid-mounted units.
  • Proven track record in taking products from design through to mass production.
  • Solid understanding of mechanical principles, fluid dynamics, thermodynamics, and hydraulic/pneumatic systems.
  • Deep knowledge of mechanical integration and structural design in maritime skid systems.
  • Proficient in SolidWorks for full assembly modeling and interference checks, and in AutoCAD for 2D technical drawings.
  • Experience with simulation tools such as ANSYS or Fluent for structural and fluid analysis, and ability to use results to guide design improvements.
  • Familiarity with maritime industry standards (ABS, DNV, LR) and certification workflows.
  • Knowledge of fabrication methods including welding, casting, and surface treatments for corrosion resistance.
  • Understanding of production assembly processes and quality control checkpoints.
  • Strong problem-solving skills applicable across design, testing, manufacturing, and field support.
  • Ability to think systematically and manage complex, multidisciplinary projects.
  • Excellent communication skills for working across engineering, procurement, production, and customer teams.
  • Detail-oriented mindset with a focus on safety, reliability, and compliance.
  • Willingness to travel occasionally for on-site commissioning, installation support, and after-sales service.
