There are several websites and companies that offer paid book review jobs, including Kirkus Media, Publishers Weekly, BookBrowse, and Online Book Club. These companies typically pay freelance reviewers to read and review books, either for specific assignments or as part of a regular reviewing team. Reviewers are usually compensated with a flat fee or a per-review rate, and may also receive free books in exchange for their reviews. Keep in mind that competition for paid book review jobs can be fierce, so it's important to have a strong writing background and a passion for reading in order to stand out to potential employers.
