Score salmon skin by using a very sharp knife to make four 1-inch lengthwise incisions into the skin. Do not cut past the skin. Allow salmon to come to room temperature by sitting unrefrigerated for at least 15 minutes.
Heat oil in a 10-inch nonstick skillet over medium-high heat. Gently lay salmon skin-side down into the hot skillet; cook until the skin is crispy and golden brown, about 2 minutes. Flip salmon and cook to brown other side, about 1 minute.
Reduce heat to low. Mix soy sauce, orange juice, maple syrup, garlic, and ginger together in the skillet. Flip salmon again to cook skin-side in the sauce. Continue cooking, basting frequently, until salmon flakes easily with a fork, 6 to 7 minutes.
