This position is located in Pasadena, California.

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 .

People choose to work at LIGO for many reasons, often with fulfilling, long-term careers. LIGO is a family-friendly laboratory and strives to ensure everyone is able to achieve the work-life balance they desire. Caltech’s benefits program offers a quality, competitive benefits package that is affordable for you and the Institute. The program provides a strong base of coverage for you and your dependents, and the ability to choose the plan and the level of coverage that best meet your needs. We also offer a 403(b) defined contribution plan to eligible staff as well as a Voluntary Retirement Savings (TDA) Plan. LIGO Caltech staff have access to the Institute’s facilities, including the athletic center, libraries, on-site daycare, professional development and enrichment classes, and Athenaeum club memberships (only Caltech site template).
