Shape Airflow for Future Generations

At Multi‑Wing Group , our mission is “Shaping airflow for future generations”. We are a global leader in custom‑designed axial fan solutions for the HVAC/R and powertrain cooling industries.

For more than 60 years, we have developed an innovative modular system that enables a very wide range of tailor‑made axial fans for customers all over the world. By optimizing airflow, we help deliver more efficient, flexible, and quieter heating and cooling – contributing to a safer, healthier planet for future generations.

To strengthen our Motors & Drives organization, we are now looking for a Mechanical Engineer, Motors & Drives to join our R&D team in Denmark.

The Role

As Mechanical Engineer, Motors & Drives , you will be responsible for the mechanical design, development, and optimization of components and subsystems for:

• Electric motors
• Drive electronics housings (VFDs and other electronics enclosures)
• Related integration parts used in axial fan applications

You will work on motor housings, shafts, bearing arrangements, sealing and cooling concepts, structural components, interfaces, and mounting systems. A key focus is to protect motors and electronics from water ingress while still providing sufficient airflow and thermal cooling in demanding industrial environments.

You will play a central role in ensuring mechanical robustness, manufacturability, reliability, thermal performance, and long‑term durability of our motor and drive solutions. You will collaborate closely with electrical motor designers, R&D colleagues, manufacturing, procurement, quality, and suppliers across regions.

What You Will Do

Mechanical design & development

• Design mechanical components for motors and drives from concept to production release.
• Create 3D models, drawings, and specifications for housings, shafts, bearings, end‑caps, covers, brackets, cooling structures, seals, drainage concepts, and assembly interfaces.
• Design and optimize electronics housings integrated into industrial fans , with strong focus on:
• Water ingress prevention
• Condensation and drainage
• Airflow and cooling performance
• Perform structural, thermal, and vibration simulations (FEA and related analyses) to ensure reliability and compliance.
• Ensure designs comply with industry standards, regulations, internal design rules, and customer specifications .

Materials & manufacturing engineering

• Select appropriate materials, coatings, and surface treatments for mechanical parts exposed to:
• Humidity, splash water, dirt, cleaning agents
• Temperature cycling and vibration
• Evaluate and balance trade‑offs between aluminum, stainless steel, coated steel, engineered polymers, die‑cast materials, and elastomers , considering:
• Corrosion resistance and galvanic compatibility
• Thermal conductivity and dimensional stability
• Chemical and UV resistance
• Weight, manufacturability, and long‑term durability
• Collaborate with manufacturing to optimize designs for machining, casting, moulding, forming, and assembly .
• Support DFM, DFA, and DFMEA activities and contribute to supplier evaluations.

Ingress protection & cooling performance

• Develop enclosure and interface concepts that minimize water ingress into motors and electronics while maintaining required cooling airflow.
• Define strategies for gaskets, seals, labyrinths, venting elements, drainage concepts, sealing surfaces, fastening strategies, and joint design.
• Balance environmental sealing and thermal dissipation to ensure robust performance in real operating conditions.
• Support validation and design improvements related to IP performance, condensation, thermal behavior, and durability .

Testing, validation & continuous improvement

• Support prototype builds , mechanical testing, design verification, and root cause analysis.
• Participate in validation related to ingress protection, thermal performance, vibration, fatigue, corrosion, and assembly robustness.
• Use test feedback and field experience to improve designs and reduce reliability risks over time.

How You Will Work With Others

Team collaboration

• Work as part of a cross‑functional product team , providing solid mechanical engineering input and judgment.
• Coordinate closely with R&D, manufacturing, procurement, quality , and suppliers to communicate requirements, risks, and design trade‑offs.

Stakeholder & customer interaction

• Translate complex mechanical challenges into clear and actionable messages for non‑technical stakeholders.
• Provide mechanical input in customer discussions , ensuring requirements around environmental protection, cooling, and integration are understood and built into the design.

Global & internal communication

• Collaborate with global teams , respecting cultural and regional differences.
• Produce clear documentation and design records accessible also to non‑engineers.
• Capture and share feedback from customers, manufacturing, field service, and internal teams so that product improvements are based on real application learning .
• Contribute to training and knowledge sharing around mechanical design, materials, ingress protection, and motor/drive integration.
• Support the process of keeping stakeholders informed about design changes, technical risks, validation outcomes, and project progress through structured and timely communication.

What We Are Looking For

Education

• Bachelor’s or Master’s degree in Mechanical Engineering, Mechatronics , or a similar field.

Experience

• Proven experience in mechanical design of rotating machinery, electric motors, pumps , or similar systems.
• Solid background in mechanical simulations (structural, thermal, vibration).

Technical skills

• Strong 3D CAD skills (e.g. SolidWorks, Creo, Inventor, NX ).
• FEA competence (e.g. Ansys, Creo Simulate or similar).
• Good knowledge of materials engineering :
• Metals, polymers, elastomers, coatings
• Corrosion‑related design and material selection in humid/harsh environments
• Understanding of manufacturing processes and their impact on design choices.
• Experience with Motor-CAD or similar tools is an advantage.
• Proficient in Microsoft Office .

Personal attributes

• Self‑motivated and proactive , with a strong sense of ownership.
• Detail‑oriented , with focus on quality and precision.
• Able to work under pressure and meet tight deadlines .
• Innovative mindset and a passion for continuous improvement .
• Comfortable working in cross‑functional and international teams .

Language & travel

• English at B2–C1 level, both written and spoken.
• Willingness to travel as needed for project meetings, testing, and collaboration with global teams.

Why Join Multi‑Wing?

• Be part of a global leader in axial fan solutions, working on technologies that directly support energy efficiency and sustainability .
• Take a key role in developing next‑generation motor and drive solutions for HVAC/R and powertrain applications.
• Work in an international, collaborative R&D environment with close links to manufacturing, suppliers, and customers.
• Enjoy an opportunity to shape products from concept to field performance , with a clear impact on quality and innovation.
