Prototype Design Engineer

Mechanical Design Engineer

We are seeking a mid-level Mechanical Design Engineer to support rapid product development across a wide range of industries. This highly hands-on role focuses on early-stage prototyping, fast iteration, and transforming concepts into functional physical products. You will work in a collaborative, fast-paced environment where speed and adaptability are critical, using CAD, 3D printing, and functional models to bring ideas to life and support end-to-end product development from early research through prototyping.

Responsibilities

• Convert existing CAD designs, often originally created for casting or traditional manufacturing, into 3D-printable, prototype-ready models.
• Develop rough CAD and surface models quickly to support early-stage product concepts and design exploration.
• Build and iterate on physical prototypes using 3D printing, machining, and off-the-shelf components to validate form, fit, and function.
• Support electromechanical system development and integrate mechanical and electrical components into cohesive assemblies.
• Assist with wearables and soft goods integration, combining textiles and hardware into functional product solutions.
• Execute mechanical testing by following defined test methods, collecting accurate data, and reporting clear, actionable results.
• Collaborate closely with cross-functional teams, including design, research, electrical, and prototyping, to refine concepts and drive product decisions.
• Apply advanced CAD practices, including working with large assemblies, applying GD&T, and using PDM tools to manage design data.
• Contribute manufacturing and process insights to help guide the transition from prototype to production.
• Help lead and support complex engineering projects, balancing technical requirements with budget and timeline considerations.

Essential Skills

• Minimum of 3+ years of experience in mechanical or product development engineering.
• Strong proficiency in Solid Works or similar CAD software, with the ability to create and modify complex mechanical designs.
• Advanced CAD expertise, including experience with large assemblies, GD&T, and product data management (PDM) systems.
• Deep mechanical design and product development background, covering concept development through prototyping.
• Hands-on experience with new product development and mechanical systems design.
• Knowledge of manufacturing processes and fabrication methods, including the transition from prototype to production.
• Experience designing injection molded parts and understanding their manufacturing constraints.
• Practical experience with rapid prototyping techniques, including 3D printing and machining.
• Ability to work effectively in ambiguous, early-stage development environments and adapt to fast-paced project needs.
• Experience with mechanical testing instruments and test execution, including data collection and analysis.
• Familiarity with FEA analysis concepts and the ability to interpret results to inform design decisions.
• Capability to support and lead complex engineering projects, considering both technical performance and capital expenditure (CAPEX) impacts.

Additional Skills & Qualifications

• Experience in a consulting, design firm, or rapid product development environment.
• Exposure to consumer products, medical devices, or industrial equipment, with an understanding of industry-specific requirements.
• Familiarity with Design for Manufacturing (DFM) and Design for Assembly (DFA) principles to support later-stage transition to production.
• Experience using AutoCAD and other CAD software tools alongside Solid Works.
• Background in mechanical engineering or a related technical discipline.
• Comfort working with GD&T to communicate design intent and tolerances.
• Understanding of manufacturing processes, including casting and various fabrication processes.
• Ability to collaborate closely with cross-functional teams and communicate technical concepts clearly.
• Strong problem-solving mindset and a passion for building and iterating on physical prototypes.
• Interest in working on end-to-end product development, from research and design through engineering and prototyping.
