What people ask about physicists, astronomers and optical engineers' work in California
Which space companies hire physicists, astronomers and optical engineers in California?
Today, The Aerospace Corporation (19 roles), SpaceX (11 roles), NASA Jet Propulsion Laboratory (7 roles), K2 Space (4 roles), Astranis (3 roles), Apex (2 roles), and 7 more. The table above lists every employer with a role open in California.
Where in California are the roles for physicists, astronomers and optical engineers?
Most are in El Segundo (21), Hawthorne (8), JPL Campus (7), Los Angeles (6), as the postings name their sites. A role that names several sites counts at each.
How much do space roles for physicists, astronomers and optical engineers in California pay?
The roles here that state pay post a median $153k/yr, with typical pay from $122k–$230k/yr; 88.2% of California's postings state their pay at all, which our research on where space jobs are compares state by state. California's law has required employers with 15 or more employees to state a pay range in job postings since 1 Jan 2023 (each state's law beside its postings). For reference, the 6,800 physicists working in California, in any industry, earn a median $207k/yr (BLS, May 2025, the public record).
Do roles for physicists, astronomers and optical engineers in California require US citizenship?
Of the 3,014 space postings in California whose text we read, 79.6% are limited to US citizens or US persons and 23.5% name a security clearance, by our research on who can apply, which compares every state. Each posting states its own rule, often citing export control under ITAR or the EAR.
How is this list made?
We read each employer's own job board every hour. A role is listed here when it is a US role and its own location line names a place in California, by the same reading as our research on where space jobs are, and its title names the profession by the same rule as the page for physicists, astronomers and optical engineers; remote roles that name no state are on the remote jobs page.
