Bring a medium pot of water to a boil and carefully lower the eggs into the water to boil for exactly 6 minutes and 30 seconds.
Immediately transfer the eggs to an ice bath to stop the cooking, then peel and set aside once cooled.
In the same pot, cook the soba noodles according to package directions, then drain and rinse with cold water to prevent sticking.
Heat the sesame oil in a large skillet over medium-high heat and add the ground pork, ginger, and garlic.
Sauté the pork until browned and fully cooked, breaking it into small crumbles with a spatula.
Season the pork with sea salt and black pepper, then stir in the sriracha and tamari until well combined.
Pour the chicken broth into the skillet and bring to a light simmer before adding the sliced bok choy.
Cook for 2 minutes until the bok choy is just tender, then divide the noodles into a serving bowl.
Pour the hot broth and pork over the noodles, top with the halved jammy eggs, and garnish with sliced green onions.
