Bring a medium pot of water to a boil and cook the soba noodles according to package directions, then drain and set aside.
In a large skillet or wok, heat the sesame oil over medium-high heat and sear the pork tenderloin strips until browned and cooked through.
Stir in the minced garlic and grated fresh ginger, sautéing for one minute until the aromatics are fragrant.
Pour in the chicken broth, tamari, and sriracha, bringing the liquid to a gentle simmer.
Add the chopped bok choy and shredded carrots to the broth, cooking for 2-3 minutes until the vegetables are tender yet still slightly crisp.
Season the broth with sea salt and black pepper to taste.
Divide the cooked soba noodles into bowls, ladle the spicy pork and vegetable broth over the top, and serve immediately.
