About the role

Key responsibilities & impact

Design, fabricate, and assemble prototype mechanisms, fixtures, and test rigs
Use 3D printing, laser cutting, manual and CNC machining, or hand tools to build prototypes
Assemble, debug, and rework hardware on the bench alongside technicians
Iterate rapidly through build, testing, learning, and improvement cycles
Start designs with sketches, free-body diagrams, and hand calculations
Size springs, motors, bearings, shafts, and fasteners based on loads, energy, and duty cycle
Choose materials and finishes based on strength, stiffness, wear, fatigue, and cost
Perform tolerance stack-ups on critical interfaces
Write test plans, instrument builds, and collect reliable data
Compare test results with calculations and identify root causes of failures
Document learnings for future engineers
Create CAD parts and release manufacturable drawings
Learn and apply design for manufacturing with suppliers and senior engineers
Integrate motors, sensors, and harnesses with electrical and software engineers
Help transition prototypes into reliable 24/7 pharmacy systems

Requirements

What you’ll need

Portfolio of hardware designed and physically made, including photos and video of projects, failures, and changes made
0–3 years of hands-on mechanical or mechatronic engineering experience, in industry or out of it
Working command of statics, dynamics, mechanics of materials, and machine design
Ability to go from a sketch to a free-body diagram to a number and defend the number
Ability to explain material, mechanism, and tolerance choices and tradeoffs
Comfortable with 3D printers, hand tools, and basic machining
Ability to debug with a caliper and a multimeter
Solid part and assembly modeling in a 3D CAD platform such as OnShape, SolidWorks, or Creo
Ability to create drawings clear enough to build from
Ownership, ability to finish work, acknowledge knowledge gaps, and learn from feedback
Nice to have: mechanisms with moving parts, mechatronics basics, tolerance analysis and GD&T, manufacturing methods, Python or MATLAB, and FEA
Ability to work from HQ three days a week
