Cook diced bacon in a skillet over medium heat until crispy. Remove bacon, leaving the fat in the pan.
Add green beans to the bacon fat and let sit undisturbed 2 to 3 minutes, then cook 6 to 8 minutes total until charred in spots.
Stir in garlic and smoked paprika, cook 30 seconds. Return bacon, season, and set aside.
Wipe the skillet and melt butter over medium heat. Cook lobster 2 to 3 minutes per side until just opaque.
Add garlic in the last 30 seconds, then remove from heat and stir in lemon juice.
Combine lobster and green beans in the pan briefly or plate together. Garnish with parsley and lemon wedges.
