All vacancies at MVO are advertised publicly and are open to any suitably-qualified candidates.

The scientific posts are funded under the contract with the University of the West Indies, who handle recruitment to these posts. These are advertised internationally to the scientific community.

Recruitment for all other posts is handled by MVO. The posts are advertised locally and using recruitment portals that focus on the Caribbean market.

MVO occasionally places contracts to purchase specific items of equipment and for short-term consultants.

Consultancies are usually part of a larger, sometimes collaborative, project and are not usually advertised.
