- Bachelor's degree in Mechanical Engineering or a closely related engineering discipline
- Minimum of 5 years of professional mechanical engineering experience
- Recent, hands-on experience using SOLIDWORKS for mechanical design, assemblies, and engineering documentation
- Ability to read, analyze, and interpret technical drawings, specifications, and engineering documentation
- Strong analytical, troubleshooting, and problem-solving skills
- Excellent written and verbal communication skills
- Demonstrated ability to work effectively in cross-functional teams
- Ability to thrive in a fast-paced, high-growth environment
- Ability to sit or stand for extended periods while working at a computer, lab bench, or assembly station
- Ability to walk between office, laboratory, and light‐manufacturing areas throughout the workday
- Ability to lift, carry, and move equipment, prototypes, or components up to 25–40 lbs
- Manual dexterity to assemble, adjust, and test small mechanical and microfluidic components
- Ability to use precision tools and instruments, including calipers, micrometers, torque drivers, and hand tools
- Ability to bend, reach, kneel, or crouch occasionally to access equipment, test setups, or storage areas
- Adequate vision and hand‐eye coordination for detailed inspection, assembly, and reading engineering drawings
