Descrição da vaga

Do you want to help design the technology powering the green energy transition?

At Nel, you’ll work at the forefront of hydrogen innovation - contributing to the design and development of electrochemical systems that power the green energy transition. In this role, you will apply your mechanical engineering expertise to complex component and system design, helping improve performance, reliability, and manufacturability.

You will collaborate closely with engineering, manufacturing, and suppliers, taking designs from initial concept through testing and production. This is an opportunity to solve complex technical challenges and make a tangible contribution in a collaborative, multidisciplinary environment.

Your New Role

As a Senior Mechanical Design Engineer, you will be a key contributor to component and complex assembly design from concept through production. Your responsibilities will span design, load distribution and structural analysis, material selection, fluid flow, dimensional tolerancing, and design for manufacturability. The role also involves frequent hands‑on prototype assembly and testing.

You will prepare detailed documentation and participate in in-depth technical reviews to ensure robust and scalable design solutions.

Your Responsibilities

You will design components and complex assemblies for electrochemical cell stacks, taking solutions from concept through testing and production. Your work will combine mechanical design, engineering analysis, hands‑on testing, and close collaboration with manufacturing.

In this role, you will:

• Perform engineering calculations and analyses covering mechanical loads, stress and deformation, fluid and gas behavior, pressure drop, flow distribution, and dimensional/tolerance stack-ups

• Create detailed CAD models, assemblies, engineering drawings, and bills of materials, applying GD&T and FEA where appropriate

• Assemble and test cell stacks and associated systems, developing test methods, selecting appropriate instrumentation, interpreting results, and validating design assumptions and analytical models

• Prepare test plans, technical reports, assembly procedures, and other engineering documentation

• Identify opportunities to reduce cost, improve reliability, and extend the functionality of existing technology

• Collaborate with manufacturing and suppliers on manufacturability, volume production, inspection criteria, component evaluation, and technical requirements

• Support non-conforming product disposition, root‑cause and failure analysis, and troubleshooting of manufacturing, test, and field issues

The above statements reflect the principal functions of the position and shall not be construed as a detailed description of all work requirements that may be inherent in the job.

What We Are Looking For

We are looking for a hands‑on, analytical, and collaborative mechanical engineer who enjoys solving complex technical challenges. You bring strong problem‑solving skills and a high level of ownership, and you are comfortable working across design, analysis, testing, and manufacturing in a multidisciplinary environment.

You bring with you:

• Bachelor’s or Master’s degree in Mechanical Engineering or equivalent, with 8+ years of relevant experience; a related PhD may count toward the experience requirement

• Strong proficiency in parametric 3D CAD for complex mechanical assemblies, preferably PTC Creo

• Demonstrated experience with GD&T and dimensional/tolerance stack‑up analysis

• Knowledge of engineering materials, including metals, polymers/elastomers, coatings, surface treatments, and material compatibility

• Familiarity with manufacturing processes including molding, machining, forming, joining, and coating

• Experience supporting manufacturing and working with suppliers on technical requirements, manufacturability, component evaluation, and quality issues

• Experience planning and executing engineering development activities, with familiarity with safe work practices and hazard analysis

• Ability to work effectively in a highly collaborative, multidisciplinary team environment

Preferred Skills

• Experience with FEA (Creo Simulate or ANSYS preferred)

• Experience with CFD or other fluid‑flow modeling, particularly pressure‑drop and flow‑distribution analysis (ANSYS Fluent preferred)

• Experience with electrochemical systems or pressure/fluid‑processing equipment, such as electrolyzers, fuel cells, flow batteries, gas separation, piping systems, or pressure vessels

What We Can Offer

• An opportunity to work in a company in a leading position in the market.

• A visible role with many exciting interfaces, internally and externally

• The opportunity to work in a global company that contributes to the green transition.

• A dynamic and highly professional working environment consisting of competent and committed colleagues.

Compensation

The anticipated annual base salary range for this position is $120,000 - $140,000. Final compensation will be determined based on factors including relevant experience, skills, education, and qualifications.
