  • Provide basic technical support to multiple physicists preparing and coordinating their target delivery dates including preparing experimental cells, installing triple-seal containment, performing basic contamination control monitoring and coordination with the shipping department.
  • Apply a fundamental knowledge of design and fabrication techniques to solve a variety of experimental instrumentation challenges of limited complexity.
  • Set up equipment, perform general troubleshooting, maintenance and minor modifications of laboratory hardware including high pressure systems.
  • Routinely inspect laboratories paying close attention to safety and housekeeping. 
  • Perform other duties as assigned.

Additional job responsibilities, at the SES.2 level 

  • Originate new instrumentation designs and features to address experimental challenges of moderate complexity.
  • Directly participate in experimental activities including preparation, execution and post-experiment analysis and summary.
