Bring a small pot of water to a boil, carefully lower the eggs in, and simmer for 6.5 minutes before transferring immediately to an ice bath.
In a separate large pot, heat the sesame oil over medium-high heat and sear the thinly sliced pork tenderloin until browned and cooked through.
Add the minced ginger and garlic to the pork, sautéing for 1 minute until fragrant and softened.
Pour in the chicken broth, tamari, and sriracha, bringing the liquid to a gentle simmer to meld the flavors.
Add the soba noodles and chopped bok choy to the broth, cooking for 4-5 minutes until the noodles are tender and the greens are wilted.
Peel the cooled eggs and slice them in half to reveal the soft, jammy yolks.
Ladle the ramen into a deep bowl, season with sea salt and black pepper, and top with the jammy eggs and sliced green onions.
