Preheat oven to 400 degrees F. Coat a shallow baking dish with cooking spray.
In a small bowl, whisk together orange juice, lemon juice, brown sugar, chili powder, lemon zest, cumin, salt, and cayenne. Using tongs, add salmon fillets to the prepared pan. Pour the orange juice mixture over the salmon and turn to coat both sides. Roast for 15 minutes, until a fork can be easily inserted into the salmon.
