Please keep an eye on our jobs site (https://jobs.zooniverse.org/) and check our Twitter account (@the_zooniverse) for future postings. Our US-based team advertises positions using the Adler Planetarium jobs page: https://www.adlerplanetarium.org/career-opportunities/
For reference, most of our team and new hires are web developers, but we do hire researchers for specific roles in the Zooniverse Team from time to time.
