• Demonstrated experience programming and troubleshooting automated liquid handlers.
• Basic programming or scripting experience in Python, C#, or another language used for laboratory automation and instrument integration.
• Experience maintaining or servicing laboratory instruments, including preventive maintenance, basic calibration, light repair, and coordination with equipment manufacturers.
• Working knowledge of molecular biology and analytical laboratory techniques, including PCR, gel electrophoresis, plate-reader assays, or HPLC.
• Strong troubleshooting skills across laboratory hardware, software, labware, reagents, and operating procedures.
• Ability to document technical issues, maintenance activities, and workflow deviations clearly and consistently.
• Strong attention to detail, organization, and commitment to safe and reliable laboratory operations.
• Effective communication and collaboration skills across scientific, engineering, operational, and vendor teams.

Preferred Qualifications

• Experience with Hamilton liquid handlers, including method development, liquid classes, deck configuration, error recovery, and routine maintenance.
• Experience operating integrated automation workcells and orchestration platforms such as Cellario, Green Button Go, Momentum, or similar schedulers.
• Familiarity with laboratory informatics systems such as LIMS and ELN, including sample tracking, metadata capture, result transfer, and workflow traceability.
• Experience connecting laboratory instruments or automation systems through device drivers, APIs, middleware, serial or network communication, or IoT integration frameworks.
• Experience supporting protein production, purification, analytical, or NGS workflows in a research or production environment.
• Experience with rapid prototyping and fabrication tools, including CAD, 3D printing, and laser cutting, for developing instrument fixtures, labware adapters, brackets, and other custom automation components.
• Experience writing SOPs, maintenance procedures, troubleshooting guides, and training materials. 

What We Offer

You will work with cutting-edge laboratory automation systems and collaborate with leading scientists and engineers on high-impact protein production, analytical, and NGS workflows.
