How much do prototype jobs pay per hour?
What is a prototype?
What is the difference between Prototype vs Product Designer?
| Aspect | Prototype |
|---|
| Role | Creates interactive models to test concepts and functionality |
|---|---|
| Skills | UI/UX design, wireframing, prototyping tools, user testing |
| Work Environment | Design teams, product development, user experience departments |
| Certifications | Design certifications, UX certifications, proficiency in prototyping tools |
While a Prototype focuses on building interactive models to test ideas, a Product Designer oversees the entire product development process, including user experience, visual design, and functionality. Prototypes are tools used within the product design process, making the roles complementary but distinct.

Position Overview:
This position is ideal for a welder/fabricator who thrives in a fast-paced prototype environment, enjoys solving complex fabrication challenges, and takes pride in precision craftsmanship. You will play a key role in supporting rapid hardware iteration, custom tooling development, and experimental engine builds within LiquidPiston's prototype machine shop.
Responsibilities:
- Fabricate, modify, and repair prototype components and test rigs to support engineering development programs.
- Perform high-quality TIG and MIG welding, brazing, and fabrication on a variety of materials including steel, stainless steel, aluminum, titanium, brass, and other alloys.
- Support prototype engine builds through the creation of custom components, fixtures, and tooling.
- Operate manual machine shop equipment including milling machines and lathes.
- Measure, inspect, and verify components using precision hand tools, gauges, cameras, and other inspection equipment.
- Assist with electrical and wiring tasks as needed for prototype systems and test equipment.
- Collaborate closely with engineers and technicians to improve manufacturability, assembly processes, and fabrication methods.
- Troubleshoot and debug mechanical systems and prototype hardware.
- Contribute ideas and practical solutions in a highly iterative R&D environment.
- Maintain a positive, adaptable, and team-oriented attitude while supporting multiple fast-moving projects.
- Experience with TIG and MIG welding in a prototype, R&D, aerospace, motorsports, defense, or advanced manufacturing environment preferred.
- Strong fabrication and metalworking skills across multiple materials and processes.
- Ability to read engineering drawings, sketches, and CAD-based concepts.
- Experience operating manual machining equipment such as mills and lathes.
- Familiarity with prototype development, rapid iteration, and custom fixture/tooling fabrication.
- Mechanical aptitude and troubleshooting ability.
- Strong attention to detail and commitment to quality workmanship.
- Ability to work independently while collaborating effectively within a multidisciplinary engineering team.
- Positive attitude, creativity, flexibility, and strong problem-solving skills.
- PTO We value work-life balance and encourage time to rest and recharge. Our benefits include 3 weeks of PTO (which covers vacation and sick time) plus 10 paid holidays.
- Comprehensive healthcare coverage: medical, dental, and vision plans
- Equity participation: RSUs for all permanent employees
- 401(k) with match: 100% up to 3%, plus 50% match for 3-5% range
- Growth opportunities: Mentorship, training, and leadership development
