01 - In a large bowl, gently combine ground beef with smoked paprika, garlic powder, onion powder, salt, black pepper, cayenne pepper, and Worcestershire sauce. Divide into 8 equal portions and shape into patties.
02 - In a small bowl, whisk together mayonnaise, sriracha, and lime juice until fully blended. Reserve for assembly.
03 - Heat a grill pan or skillet over medium-high heat. Cook each patty for 3 to 4 minutes per side until reaching desired doneness. During the final minute of cooking, place one slice of pepper jack cheese on each patty and cover to allow melting.
04 - In a separate pan or on the grill, melt butter over medium heat. Place slider buns cut side down and toast until golden brown.
05 - Spread spicy mayo on both cut surfaces of each bun. Layer bottom bun with lettuce leaf, cooked beef patty with melted cheese, jalapeño slices, and red onion. Top with remaining bun half.
06 - Transfer sliders to serving platter and serve immediately while hot.
