R&D Mechanical Engineer

R&D Mechanical Engineer, Motors & Drives Location: Senago, Italy (MW Italy) or Randers, Denmark (MW Denmark) Department: R&D – Motors & Drives

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.
