Bring a large pot of generously salted water to a boil. Shuck the corn and cut off the kernels (you should have about 2 cups).
Add the pasta to the boiling water and cook until al dente according to the package instructions. Add the green beans and corn kernels about 2 minutes before the pasta is done cooking. Reserve 1/4 cup of the pasta cooking water. Drain the penne, green beans and corn, toss with a drizzle of oil in a large serving bowl.
Heat the oil in a large saucepan over medium heat for 30 seconds. Add the garlic and red pepper, and cook, stirring, until fragrant, about 2 minutes. Pour in the wine and reduce until the alcohol smell is gone and the sauce is golden in color, 3 to 4 minutes. Adjust the heat to medium-low and stir in the shrimp, lemon zest and 1 teaspoon salt and cook, stirring occasionally, until the shrimp are pink and just cooked through, about 2 minutes.
Add the cooked pasta, green beans, corn, parsley, reserved pasta water, tomatoes, lemon juice, 2 teaspoons salt and 1/2 teaspoon pepper to the shrimp. Toss and taste, checking to make sure it is generously seasoned before chilling. Chill for at least 1 hour, up to 4 hours.
