Place the jalapeño, garlic, cilantro, olive oil, orange juice, lime juice, white wine vinegar, chili powder, salt, cumin, oregano, chili powder, and black pepper in a large bowl and whisk together. Set aside.
Place the steak in a non-reactive baking dish and pour the marinade on top.
Cover with plastic wrap and place in the fridge to marinate for 2-4 hours (but no more than 4 hours), turning often.
When ready to cook, preheat the grill to medium-high.
Take the steak out of the baking dish and pat dry with paper towels.
Lightly drizzle the steak with some olive oil and season with salt and pepper to personal taste.
Transfer the steak to the grill and grill for 8 minutes per side, turning once.
Remove steak from the grill, cover, and rest for 5 minutes before slicing against the grain.
