Bring a large pot of salted water to a boil. Add the pasta and cook until just al dente, about 10 minutes. Add the escarole and cook, stirring occasionally, until tender, about 2 more minutes.
Meanwhile, toast the pine nuts in a large skillet over medium-high heat, about 1 minute. Add 1 tablespoon olive oil, the breadcrumbs, and salt and pepper to taste; cook until golden, about 2 minutes. Transfer the mixture to a plate. Wipe out the skillet, add the pancetta and cook until crisp, about 5 minutes. Transfer to paper towels and blot dry.
Add the remaining 1 tablespoon olive oil to the skillet, then add the garlic and jalapeno and cook until fragrant, about 1 minute. Drain the pasta and escarole, reserving 1 cup cooking water, and add to the skillet. Add half of the pancetta and toss, drizzling in enough pasta water to moisten. Season with salt and pepper.
Divide the pasta among bowls, top with the breadcrumb mixture, remaining pancetta and the parmesan. Drizzle with olive oil.
