Add soy sauce, brown sugar, sriracha and water to a medium bowl. Reserve 1/4 of the marinade.
Add the chicken to the bowl and marinade while the oil is heating up.
Heat oil in a large skillet or cast iron grill pan.
When the pan is nice and hot add in the chicken skin side down. Cook for 5 minutes, flip and cook for an additional 5-10 minutes or until fully cooked.
Brush the remaining marinade mixture on top of the chicken.
Serve immediately with fresh cilantro and lime wedges if desired.
