Riley Sennott, 26, is listed as a "senior advisor" in an internal NASA directory, similar to the nebulous titles given to some DOGE staff in other agencies. His name and involvement with DOGE have not been previously reported.

Like many other DOGE workers, he deleted his LinkedIn profile and made his X account private in recent months. However, Sennott did not make the Google Calendar linked to his personal email address private.

Anyone with the address could see every appointment Sennott had on the calendar going back to 2016. On January 6, for example, the calendar included a 15-minute event titled "Riley Sennott and DOGE Recruiting." The invite came from a Gmail address that DOGE appeared to be using for recruiting.

A calendar appointment from 2023 noted that Sennott "is currently working with a non-profit team in Ukraine to efficiently deliver aid and support evacuations." The blurb said that Sennott studied symbolic systems and environmental studies in college, "briefly dabbled in consulting," and has an "entrepreneurial spirit." His calendar also showed several events related to an internship at Booz Allen Hamilton in 2021.

"The Department of Government Efficiency (DOGE) has arrived onsite at the agency. We anticipate that they will start reviewing our contracts to find efficiencies," the email reads, according to a copy reviewed by BI.
