LIGO Laboratory (the Laser Interferometer Gravitational-wave Observatory) seeks a highly motivated and skilled Vacuum Systems Engineer to join its team.
This position is located in Pasadena, California.
LIGO Laboratory is a National Science Foundation major facility dedicated to observing the newly discovered gravitational-wave universe. Jointly operated by the California Institute of Technology and Massachusetts Institute of Technology, the LIGO Laboratory operates world-leading observatories near Richland, WA and Baton Rouge, LA as well as R&D centers on the Caltech and MIT campuses. The LIGO Laboratory's mission spans a broad and vibrant array of activities related to gravitational-wave physics and astronomy, including detector operations, R&D toward detector improvements, gravitational-wave astrophysics, observatory operations, and education and public outreach.
Life at Caltech/LIGO LIGO Caltech is located on the campus of the California Institute of Technology in Pasadena, California, near the foothills of the San Gabriel Mountains. Caltech has an extraordinary science impact across many fields. Its small size creates a community where innovation and collaboration are the norm. Caltech manages the Jet Propulsion Laboratory (JPL) for NASA, the leading US center for the robotic exploration of the Solar System. Caltech also operates large-scale research facilities such as the Palomar and Keck Observatories.
Pasadena is a city known for its contributions to science and technology, rich history, cultural treasures, and scenic beauty. The year-round comfortable weather creates a desirable environment for life and ideas to thrive. See Bill Nye's take on our city .

Essential Job Duties
Oversee the vacuum preparation lab. The vacuum preparation lab provides an equitable share of support for in-vacuum components required for LLO, LHO, LASTI and the 40m.
Oversee the optical contamination lab. The optical contamination lab has two high finesse optical contamination cavities for the purpose of qualifying/testing materials for use in the LIGO Ultra-High Vacuum (UHV) system.
Support the vortex lab. The vortex lab has an UHV test system to investigate and characterize water vapor adsorption and desorption on simulated LIGO beam tube surfaces.
Support the LIDT lab. The Laser Induced Damage Threshold (LIDT) Lab is used to quantify the effects of irradiation level on surface damage of ion beam sputtered coatings under vacuum.
Support other research labs at Caltech as assigned.
Specifically, the individual would:
Perform cleaning, vacuum baking and RGA qualification for UHV parts (primarily focused on one off items that require special handling or processing).
Perform proof and leak testing (via a range of techniques and processes) as required for specific parts to be qualified for use in the LIGO vacuum system.
Import data into both MATLAB and Mathematica and utilize existing scripts to analyze and post process RGA scans of e.g., bake loads and vacuum systems.
Support on-going operations with investigations of possible materials compatibility issues as well as qualifying alternative materials).
Keep assigned equipment including e.g., vacuum chambers, clean room(s) and associated test equipment running, maintained and supplied and keep assigned laboratories stocked and organized.
Execute vent and pump down activities by qualifying performance of vacuum equipment, venting/pumping large volumes, removing/installing chamber doors, leak checking, analyzing RGA data, and operating gate valves.
Utilize a scanning dark field microscope for automated defect inspection on optics.
Operate and run lasers.
Design, implement, and test controls systems for vacuum equipment operation and safety interlocks.
Write specifications, select, and procure vacuum equipment including turbo and ion pumps, gauges, valves; interface with suppliers.
Implement modifications to vacuum boundaries when required; install and test vacuum components/equipment and leak check joints.
Support other engineering staff and scientists performing experiments involving the vacuum systems and equipment. Ensure all operations are performed safely, minimizing risk to machines.
Work individually and in a team environment.
Travel to the other LIGO sites (Hanford, Livingston and MIT) will be required (up to 25% of time).
BS in Mechanical, Aerospace, Chemical or Systems Engineering; Physics; Material Science; or a related scientific or engineering field. We will also consider 5 years of experience in a related field in lieu of a degree.
2+ years of vacuum-related engineering or scientific research work experience.
Demonstrated proficiency in operation, analysis, and performance characterization of high- or ultra-high vacuum systems.
Knowledge and experience in selection and application of UHV-compatible materials.
Be proficient with computer applications (e.g., Word, Excel, Web applications).
Possess the ability to read and understand mechanical and electrical drawings, technical specifications and assembly instructions.
Possess good verbal and written communication skills, ability to work well in a team, and a high degree of professional discipline.
