What does a typical day look like for a Prototyping Engineer?

A typical day for a Prototyping Engineer often involves collaborating with design and development teams to translate concepts and sketches into working physical models. You may spend time using CAD software, operating fabrication equipment like 3D printers, and assembling or testing prototypes for functionality. Troubleshooting issues and iterating designs based on test results are frequent tasks. This role requires consistent teamwork with engineers, designers, and sometimes clients to ensure the prototyping process aligns with overall project goals.

What is a Prototyping Engineer job?

A Prototyping Engineer is responsible for designing, developing, and testing prototypes of new products or components. They work with design teams to refine concepts, select materials, and ensure that prototypes meet functional and performance requirements. This role involves using various fabrication techniques, such as 3D printing, CNC machining, and electronics assembly. Prototyping Engineers collaborate with R&D, manufacturing, and quality teams to iterate and improve designs before full-scale production. Their goal is to validate ideas quickly and efficiently, reducing development time and costs.

What are the key skills and qualifications needed to thrive in the Prototyping Engineer position, and why are they important?

To thrive as a Prototyping Engineer, you need strong skills in mechanical or electrical engineering, rapid prototyping, and CAD design, usually supported by a relevant engineering degree. Knowledge of 3D printing, CNC machining, and prototyping software (such as SolidWorks or AutoCAD) is typically essential, along with familiarity with relevant safety standards. Creative problem-solving, collaboration, and effective communication are valuable soft skills in this role. These abilities enable engineers to quickly turn ideas into functional prototypes, ensuring efficient product development and iterative testing.

Job description

Candidate should live within driving distance of the following areas: Wichita, KS; Lawton OK; or Round Rock, TX
Job Purpose/Summary
This role is for a Rapid Prototype Engineer II to design, fabricate, assemble, and validate hardware prototypes supporting research and development efforts across mechanical, electrical, and integrated systems.
You will work alongside hardware, electrical, and software engineers to rapidly translate concepts into functional prototypes using a combination of in-house production capabilities and external manufacturing partners. This role includes hands-on ownership of fabrication, assembly, wiring, and system integration, while coordinating outsourced production and finishing processes as needed.
This is an individual contributor role with responsibility across prototype development, vendor coordination, and build/test execution in fast-paced, iteration-driven environments.
Duties and Responsibilities
  • Design, fabricate, and modify prototype components using variety of tools (e.g., 3D printers, CNC machines, laser cutters, and hand tools).
  • Evaluate designs and select appropriate materials, fabrication methods, and finishing processes (e.g., anodizing, painting, coating, polishing).
  • Build and assemble mechanical and electro-mechanical systems, including structural, enclosure, and mounting solutions.
  • Design and fabricate wiring harnesses and cables, including cutting, crimping, soldering, labeling, and routing for prototype systems.
  • Integrate electrical components, connectors, and subsystems, ensuring reliable and serviceable wiring practices.
  • Coordinate with third-party vendors for outsourced manufacturing (e.g., machining, PCB fabrication, cable assemblies, finishing services).
  • Manage vendor relationships, including sourcing, quoting, scheduling, and quality verification of delivered parts.
  • Perform functional testing and quality assurance on prototypes to validate performance, reliability, and design intent.
  • Troubleshoot mechanical and electrical issues, and iterate on designs based on test results and team feedback.
  • Support system integration efforts across mechanical, electrical, and embedded subsystems.
  • Document build processes, wiring diagrams, bill of materials (BOMs), and vendor selections.
  • Source tools, materials, and equipment required to support prototyping and fabrication efforts.
  • Package and ship prototypes to internal teams and partners, ensuring proper handling, protection, and documentation.
  • Maintain a safe, clean, and organized prototyping and production environment.
  • Collaborate with cross-functional engineering teams to support rapid development cycles.
  • Complete other duties as requested.

Qualifications
  • Eligible to obtain a U.S. Security Clearance - U.S. Citizenship required.
  • Formal education in Mechanical Engineering, Electrical Engineering, Manufacturing Engineering, or a related field, or a suitable mix of education and hands-on experience.
  • Professional experience working in prototyping labs, machine shops, or makerspace environments.
  • Hands-on experience with fabrication tools and processes (e.g., 3D printing, CNC machining, laser cutting, manual fabrication).
  • Experience building and assembling mechanical and electro-mechanical systems.
  • Experience designing and fabricating wiring harnesses and cables, including crimping, soldering, connector selection, and cable management.
  • Strong understanding of materials (plastics, metals, composites) and finishing processes.
  • Experience coordinating with external vendors and managing outsourced manufacturing.
  • Ability to read and interpret technical drawings, CAD models, schematics, and wiring diagrams.
  • Strong troubleshooting and problem-solving skills across mechanical and electrical systems.
  • Ability to manage multiple prototype efforts in parallel in fast-paced environments.
  • Strong communication skills for collaboration with cross-functional teams.

Preferred Qualifications
  • Experience with CAD software (e.g., SolidWorks, Fusion 360, or similar).
  • Experience with basic electronics prototyping and integration (PCB handling, power systems, connectors).
  • Familiarity with design for manufacturability (DFM) and design for assembly (DFA) principles.
  • Experience working with rapid prototyping and low-volume manufacturing vendors.
  • Knowledge of cable standards, harness best practices, and environmental considerations (strain relief, shielding, routing).
  • Experience supporting early-stage product development or research programs.

Working conditions
  • Employees may be called upon to participate in in-person meetings, trainings, or company functions at Knowmadics offices or other designated locations. Travel in support of business operations may also be required, and employees are expected to comply with these obligations as part of their position.
