Twist Bioscience
Mechanical Engineer - Automation Systems (Contract)
About this role
Twist Bioscience seeks a contract mechanical engineer to design, build, and deploy custom automation systems for DNA synthesis manufacturing. This hands-on role spans CAD design through lab-floor assembly and testing, requiring expertise in SolidWorks, electromechanical integration, and fluidics systems over a 2–3 month engagement in Wilsonville, Oregon.
What you'll do
- Design automated systems and custom mechanical components using SolidWorks to meet hardware requirements
- Specify and procure mechanical, electromechanical, and fluidics components for complete automation platforms
- Collaborate with cross-functional teams (systems engineers, electrical engineers, scientists) to refine requirements and optimize designs
- Assemble, test, debug, and verify prototype systems on-site alongside technicians and engineering staff
- Perform mechanical analyses including tolerance stack-up and design verification
- Create and maintain comprehensive engineering documentation (3D models, drawings, BOMs, revision control)
What they're looking for
- SolidWorks (part, assembly, and drawing design)
- Custom automation and mechatronic systems design
- Electromechanical component specification and integration (motors, actuators, sensors)
- Fluidics systems design (pumps, valves, regulators, manifolds)
- Tolerance analysis and mechanical design principles
- Engineering documentation and BOM creation
- Design for assembly and manufacturability
- PLM systems (Dassault Systèmes 3DEXPERIENCE preferred)
