Preheat your grill to medium-high heat.
Pat the shrimp dry and toss with olive oil, salt, pepper, smoked paprika, and garlic powder.
Thread shrimp onto skewers for easy grilling.
In a bowl, whisk together parsley, cilantro, garlic, red pepper flakes, olive oil, and vinegar. Season with salt and pepper.
Grill the shrimp for 2–3 minutes per side until pink and slightly charred.
Serve hot, drizzled with chimichurri sauce.
