Combine olive oil, brown sugar, smoked paprika, chipotle chile powder, and lime juice in a bowl.
Mix until the sugar dissolves and the spices are evenly distributed.
Add the shrimp to the marinade, ensuring each piece is well-coated.
Let the shrimp marinate for 15 minutes at room temperature.
You can marinate for up to 3 hours in the refrigerator for a stronger flavor.
Preheat your grill to medium-high heat.
Make sure the grates are clean and lightly oiled to prevent sticking.
Thread the marinated shrimp onto skewers evenly.
This keeps the shrimp from falling through the grates and makes flipping easier.
Grill the shrimp skewers for about 1.5 minutes on each side.
The shrimp should be opaque and slightly charred.
