About the job
Job Description:
The R&D Design Engineer is responsible for the research, design, development, testing, and validation of precision welding systems including laser and advanced arc welding systems. This role will serve as a key mechanical and thermal engineering contributor within the R&D team, working closely with electrical, optical, software, welding/application, and other engineering functions to develop and demonstrate new technologies and product concepts.
The engineer will also collaborate closely with the New Product Development (NPD) team to mature R&D concepts, establish robust engineering solutions, and support an effective transition from technology development into product development and commercialization. The role may interface with manufacturing, suppliers, sales, and service as needed to incorporate manufacturability, customer, and field considerations into the design.
The ideal candidate combines strong mechanical design capabilities with expertise in thermal systems and cooling technologies, a hands-on approach to prototype development and testing, and the ability to translate early-stage concepts into validated engineering solutions suitable for transition to product development.
Essential Responsibilities:
Design and develop mechanical and thermal systems for next-generation laser and advanced arc welding technologies.
Collaborate with electrical, optical, software, welding/application, and other R&D engineers to develop integrated system concepts and solutions.
Develop and build prototypes and proof-of-concept systems to evaluate new technology and design approaches.
Perform engineering analysis, calculations, simulations, and technical assessments to guide design decisions and resolve technical risks.
Develop thermal management and cooling solutions for laser sources, power electronics, optics, and other high-power system components.
Participate in system architecture development, technology trade-off studies, and design reviews.
Create engineering models, drawings, bills of materials, test plans, and technical documentation appropriate to the maturity of the R&D design.
Evaluate and work with suppliers and technology partners on new components, materials, and technologies.
Collaborate with NPD engineering teams to mature validated R&D solutions and support effective technology transfer into product development.
Work with suppliers to identify and qualify components and materials.
Support regulatory and industry compliance requirements.
Interface with manufacturing, quality, regulatory, sales, and service as needed to incorporate manufacturability, compliance, customer, and field considerations into technology development.
Required Qualifications:
Bachelor's degree in: HVAC/R Engineering Technology
Mechanical Engineering Technology
