Research vessel jobs include roles similar to the crew of any other boat, such as captain, first mate, engineer, cook, and deckhand. As part of your duties on a research vessel, you help run and maintain a marine ship and otherwise ensure the vessel functions properly so that researchers can perform a study or experiment. As a captain, you operate and steer the ship and oversee all crew members. As an engineer, you manage equipment operations and maintenance. Most ships do not have full-time research staff as employees. Rather, scientists simply use the ship and are employed elsewhere.
