Gravitational-Wave Research Scientist III

New ideas are all around us, but only a few will change the world. That’s our focus at JPL. We ask the biggest questions, then search the universe for answers—literally. We build upon ideas that have guided generations, then share our discoveries to inspire generations to come. Your mission—your opportunity—is to seek out the answers that bring us one step closer. If you’re driven to discover, create, and inspire something that lasts a lifetime and beyond, you’re ready for JPL. Located in Pasadena, California, JPL has a campus-like environment situated on 177 acres in the foothills of the San Gabriel Mountains and offers a work environment unlike any other: we inspire passion, foster innovation, build collaboration, and reward excellence. Overview The Jet Propulsion Laboratory (JPL), California Institute of Technology, invites applications for a Staff Scientist position working on Gravitational Wave science. JPL offers a unique research environment that bridges the gap between fundamental science and space‑mission implementation. We are committed to fostering an enriching, rewarding research environment with strong support for professional and personal development. Responsibilities We are looking for an innovative Scientist III to play a pivotal role in developing data analysis algorithms for the Laser Interferometer Space Antenna (LISA). As JPL expands its capabilities in low‑frequency gravitational‑wave astronomy, this role is essential for developing the sophisticated pipelines required to untangle complex, overlapping signals in order to transition noisy data into astrophysical insight. Develop Core Pipelines: Design, implement, and validate novel data analysis algorithms, noise reduction algorithms, low‑latency alert pipelines, and global‑fit architectures tailored for low‑frequency gravitational‑wave data. Bridge Theory and Data Integrate instrumental, environmental, and astrophysical systematics into robust statistical frameworks to isolate faint cosmological and astrophysical signals from instrument noise and background signals. Leverage the Caltech‑JPL Ecosystem: Actively collaborate with JPL's Galaxies and/or Cosmology Groups, Caltech’s Theoretical Astrophysics Relativity (TAPIR) group, and experts across Caltech's Division of Physics, Mathematics, and Astronomy (PMA). Strengthen US LISA ties: Work collaboratively to strengthen ties across the NASA LISA ecosystem at GSFC, MSFC, and JPL. Astrophysical Modeling: Advance and connect theoretical models to data analysis pipelines through development of individual source waveform models and/or astrophysical populations. Shape Long‑Term Capabilities: Help develop future space‑based mission concepts, ground‑segment architectures, and enabling data technologies for the next generation of space physics. Qualifications A Ph.D. in Physics, Astronomy, Astrophysics, or a related discipline with a minimum of 3 years of post‑doctoral or relevant research experience. Deep technical foundation in gravitational‑wave data analysis methodologies. Proven track record of scientific excellence in gravitational‑wave astronomy, evidenced by peer‑reviewed publications and presentations at major international conferences. Strong interpersonal skills and a demonstrated ability to thrive within a highly collaborative, multi‑institutional team environment. Excellent written and verbal communication skills, along with a proactive commitment to fostering an inclusive, diverse, and dynamic research culture. Desired Skills Direct experience developing data analysis algorithms, astrophysical models, or software frameworks for gravitational wave observatories. Proficiency in applying machine learning or advanced data science methodologies to complex, continuous astrophysical datasets. Broader expertise in multi-messenger astrophysics or related fields of cosmology (e.g., ground‑based GW networks, pulsar timing arrays, or cosmic microwave background analysis). Demonstrated potential or experience in successfully proposing for research funds as a Principal Investigator or Co‑Investigator. Note Cover Letter: Describing your vision for your role at JPL as a leader and contributor to the field of space-based gravitational‑wave science. Curriculum Vitae: Including a bibliography of peer‑reviewed and other publications. Research Statement: Detailing your research experience and future research objectives (no more than 3 pages). References: Contact information for at least three professional reference writers. Applications received by August 15, 2026 will receive full consideration.
