What is a design and development engineer?

Design and Development Engineers are professionals who create, test, and refine products or systems, often working in fields like manufacturing, electronics, or automotive engineering. They use technical knowledge and creativity to design new products or improve existing ones, ensuring they are functional, cost-effective, and meet safety standards. Their roles often involve collaborating with other engineers, using computer-aided design (CAD) software, and overseeing the development process from concept to production. These engineers play a crucial role in turning ideas into real-world solutions.

What are the key skills and qualifications needed to thrive as a design and development engineer?

To thrive as a Design and Development Engineer, you need strong analytical skills, a background in engineering (such as a bachelor's degree in mechanical, electrical, or related disciplines), and proficiency in product design principles. Familiarity with CAD software (like SolidWorks or AutoCAD), project management tools, and relevant industry certifications (such as Six Sigma or PMP) is typically required. Creativity, problem-solving, and effective teamwork are critical soft skills that set top professionals apart in this role. These skills ensure the successful design, prototyping, and launch of innovative products that meet both technical and market demands.

How does a design and development engineer typically collaborate with cross-functional teams during a product lifecycle?

Design and Development Engineers work closely with multidisciplinary teams, including manufacturing, quality assurance, and marketing, throughout a product’s lifecycle. They are often responsible for translating design concepts into prototypes, gathering feedback from stakeholders, and incorporating changes to ensure the final product meets both technical and customer requirements. Regular meetings, design reviews, and collaborative problem-solving sessions are common, making strong communication skills essential for success in this role.

What is the difference between Design And Development Engineer vs Mechanical Engineer?

AspectDesign And Development EngineerMechanical Engineer
Primary FocusDesigning and developing new products or systemsApplying principles of mechanics to analyze, design, and improve mechanical systems
Required CredentialsBachelor's in Mechanical, Industrial, or related engineering; often includes CAD certificationsBachelor's in Mechanical Engineering; licensure may be preferred
Work EnvironmentDesign labs, R&D departments, manufacturing settingsManufacturing plants, testing labs, design offices
Industry UsageProduct development, automotive, aerospace, consumer electronicsManufacturing, automotive, aerospace, energy sectors

The main difference is that Design And Development Engineers focus on creating and refining new products and systems, while Mechanical Engineers apply mechanical principles to analyze and improve existing mechanical systems. Both roles require similar educational backgrounds and often work in overlapping industries, but their core responsibilities differ in scope and focus.

Job description

At JetCool, a Flex company, we're at the forefront of liquid cooling innovation, delivering advanced solutions that empower our partners in AI and high-performance computing. United by a shared purpose, our teams are pushing the limits of what's possible and tackling complex challenges.
A career at JetCool offers the opportunity to make a real impact by helping build smarter, more sustainable data centers. Together, we're not just advancing technology - we're redefining cooling standards to create a more sustainable tomorrow.
Job Summary
Job Description
To support our extraordinary teams who build great products and contribute to our growth, we're looking to add a Mechanical Development engineer located in Littleton, MA.
Reporting to the Product Manager the Mechanical Development engineer The Sr. Mechanical Design Engineer will own the design, analysis, validation, and refinement of mechanical components and assemblies that enable reliable, high efficiency liquid cooling. They will work closely with Thermal, Electrical, Product Development, Manufacturing, and Quality teams to take products from concept through launch and into scalable production.
What a typical day looks like:
Mechanical Design & Development
  • Own mechanical design for liquid cooling components including cold plates, manifolds, quick-disconnects, tubing assemblies, housings, and chassis interfaces.
  • Create and manage detailed CAD models, 2D drawings, GD&T, and tolerance stack-ups to ensure robust, manufacturable designs.
  • Select materials and finishes to address corrosion, galvanic compatibility, cleanliness, pressure containment, and long-term durability in liquid cooling environments.
  • Drive sealing strategies using O-rings, gaskets, welds, brazes, and adhesives matched to coolant chemistry and operating conditions.

Engineering Analysis
  • Perform engineering calculations and simulations related to mechanical stress, thermal expansion, fatigue, vibration, flow/pressure, and structural integrity.
  • Collaborate with thermal engineers to optimize mechanical features influencing flow distribution, pressure drop, fin/channel geometry, and heat transfer efficiency.
  • Conduct DFM reviews with suppliers to align machining, brazing, and fabrication methods with design requirements.

Prototyping & Validation
  • Build and iterate on prototypes to evaluate fit, finish, assembly, and performance.
  • Develop mechanical validation plans for pressure tests, leak testing, burst testing, vibration/shock, environmental exposure, thermal cycling, and dimensional inspection.
  • Design test fixtures and support automated data collection where needed.
  • Lead root cause analysis for failures (e.g., leaks, deformation, material incompatibility) and implement corrective design changes.

Manufacturing & Supplier Engagement
  • Collaborate with manufacturing engineering and suppliers on fabrication, machining, brazing, plating, and sealing processes.
  • Define critical-to-quality (CTQ) characteristics and participate in supplier qualification.
  • Review and approve tooling, control plans, and inspection criteria for new mechanical parts.
  • Support build events (EVT/DVT/PVT) and ensure mechanical components meet functionality, quality, and reliability targets.

Cross-Functional Collaboration
  • Work with Program Management and Product Development to translate product requirements into mechanical specifications.
  • Partner with Thermal and Electrical teams to ensure system-level integration of cooling hardware with processors, boards, and rack infrastructure.
