Contract R&D Prototype Engineer
Who We Are Looking For

• A hands-on, analytical engineer with strong mechanical and prototyping skills to help turn an early-stage concept into a functional and testable prototype.
• This role will work closely with R&D engineers to develop concepts, fabricate and integrate hardware and electrical components, execute structured experiments, troubleshoot issues, and document learning.
• The successful candidate is comfortable making progress with limited day-to-day direction while working within approved engineering and laboratory controls.

Key Responsibilities

• Collaborate with R&D engineers to translate prototype requirements, sketches, and concepts into practical mixer system designs and build plans.
• Design, assemble, modify, and debug prototype mixer hardware, support frames, fluid paths, and test fixtures.
• Integrate pumps, motors, agitators, tubing, valves, connectors, sensors, instrumentation, and basic controls into a working prototype system.
• Procure and organize prototype components and fabricated parts
• Execute controlled experiments to characterize product performance
• Collect, organize, and analyze test data
• Troubleshoot mechanical, electrical, controls, and process issues
• Prepare prototype equipment for design reviews, internal demonstrations, and future evaluation activities

Required Qualifications

• Associate or bachelor's degree in Mechanical Engineering, Electrical Engineering, Chemical Engineering, Engineering Technology, or a related technical discipline, or equivalent relevant experience.
• Prototype fabrication or bioprocess mixing experience using pumps, mixers, valves, sensors, filters, tubing, and single-use bioprocess equipment
• At least 3 years of hands-on experience designing, building, testing, or troubleshooting prototype equipment, laboratory systems, industrial machinery, or automation hardware.
• Strong mechanical and electrical aptitude and demonstrated ability to use common hand tools, measurement tools, and fabrication equipment safely.
• Ability to work independently, manage changing priorities, and collaborate effectively in a cross-functional R&D environment.

Preferred Experience

• Instrumentation and data acquisition for pH, conductivity, temperature, pressure, flow, weight, speed, or similar measurements.
• Basic electrical assembly, motor controls, PLC integration, automation, or programming.
• Bioprocess experience with media preparation, powder handling, contamination control, or work in a regulated development environment.
