An Engineer (エンジニア Enjinia?) is a member of Border's technical support staff who handles most of Border's technology-related parts, such as analyzing Neighbor technology and developing new Triggers. They are also responsible for customizing a Border agent's Trigger.
There are two ways for someone to become an Engineer:
- Request to become one when enlisting.
- Request for a transfer after enlisting.
