Software Engineer, AI 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 candidate will fulfill the role of a Software Engineer for the Deep Synoptic Array (DSA) project. The candidate will be the lead engineer for the Chronoscope (CHR) subsystem of the project. The Chronoscope subsystem will enable a world‑leading, near real‑time search for pulsars and fast radio bursts; the discovery of pulsars, and the discovery of the spin‑down of a binary pulsar system due to gravitational radiation, were both awarded Nobel prizes.

The role involves the design, implementation, and testing of GPU compute kernels, and associated host code, for the CHR real‑time pipeline. Particular challenges include high‑throughput beamforming via a Fourier transform approach, the removal of the effects of interstellar and intergalactic dispersion, and pulsar candidate identification.

The candidate will be based at the Caltech campus. This role includes opportunities for growth through wide‑ranging interactions within the world‑leading Caltech astronomy department and with a range of close external collaborators, and mentorship within the group.

• Responsible for the design, implementation, and testing of GPU computer kernels, and associated host code, for the CHR real‑time pipeline.
• Will make recommendations on the requirements for CHR hardware design, and on the design of the experimental setup.
• Will work in close collaboration with Prof. Vikram Ravi and his group, and key DSA‑2000 personnel both local and remote, in a team‑based environment.
• Will travel to OVRO, as needed, to collaborate with and learn from engineering staff.
• Other duties as assigned.

• PhD in Astrophysics or related discipline (science/engineering/math).
• More than five years hands‑on programming experience in CUDA C++.
• Experience working in a scientific collaboration.

• Exposure to low‑level network programming.
• Experience with Linux systems.
• Expertise in Python.

• Resume

$120,000 - $165,400 Per Year
