We are seeking a Lab Automation Engineer Contractor to program, operate, and maintain liquid handling platforms and integrated workcells supporting protein production, analytical, and next-generation sequencing workflows.

This hands-on role is responsible for keeping laboratory automation systems running reliably. You will support daily operations, translate established protocols into automated methods, troubleshoot equipment and workflows, perform routine instrument maintenance, and coordinate service with manufacturers.

We are looking for a dependable, hands-on team member who takes ownership of laboratory automation operations. The ideal candidate combines practical liquid-handling experience with strong troubleshooting, documentation, and communication skills.

You will program, modify, test, and operate liquid handling methods. This includes preparing labware and reagents, monitoring automated runs, documenting deviations, and supporting recovery from workflow interruptions.

You will help keep laboratory instruments and integrated workcells operational through routine and preventive maintenance, calibration checks, light repairs, and structured troubleshooting. You will also coordinate service and repair with manufacturers when needed.

You will operate integrated automation systems, including liquid handlers, plate storage and transport systems, analytical instruments, and scheduling software. You will maintain SOPs, troubleshooting guides, maintenance records, and operating instructions.

You will also support sample tracking, run documentation, and data transfer to LIMS, ELN, and downstream systems, while training and supporting scientists and operators who use the automation equipment.
