Electronics Engineer

Caltech is a world-renowned science and engineering institute that marshals some of the world's brightest minds and most innovative tools to address fundamental scientific questions. We thrive on finding and cultivating talented people who are passionate about what they do. Join us and be a part of the diverse Caltech community.

The Owens Valley Radio Observatory (OVRO) is one of the largest and most advanced university-operated radio observatories in the world. Managed by the California Institute of Technology (Caltech), OVRO serves as a premier research hub dedicated to pushing the boundaries of radio astronomy and astrophysics.

Job Summary

We are seeking an electronics engineer for OVRO to develop an instrument for fast radio burst (FRB) detection in the microwave domain. This instrument will utilize existing 3.5-m-diameter antennas that will be repurposed and upgraded to open up a new frequency window for FRB science. The project principal investigators (PIs) and co-PIs are based at Cornell University, the University of Chicago, and Caltech. This position is an opportunity to be part of a diverse team working on leading astronomical instrumentation with prospects of increasing seniority at the observatory.

Under the guidance of senior staff, the selected candidate will review the status of the antennas, including the drives, electronics, receivers, software, and infrastructure, and prepare a plan to implement and commission an operating instrument. They will be responsible for executing the plan with the assistance of other staff as necessary. The goal is to repurpose existing antennas along with new specialized hardware to extend the observing range for fast time-domain astronomy. The development will be in close collaboration with other partners who will provide antenna control software and digital acquisition and processing hardware. The selected candidate will report directly to the Site Director as well as being responsive to the goals of the PI. As part of the OVRO staff, they will work with other engineers and technicians and may be called on to contribute to other projects. In the future, the scope of work will transition over to other projects that the observatory will be developing. The position will be conducted in-person and on-site at the OVRO near Big Pine, California.

For more information about the position, please contact the hiring manager and OVRO Site Director, James Lamb, lamb@caltech.edu.

Applications will be reviewed on a rolling basis. Applications received by Tuesday, December 8, 2026 will receive full consideration. The position will remain open until filled.
