Cook noodles according to package directions. Drain and set aside.
Using a sharp knife, cut the corn off the cob. Heat a large skillet over medium-high heat with a small amount of olive oil. Once hot, add in the corn and cook for about 5-10 minutes until tender and some of the pieces are beginning to brown.
In a small bowl mix together the Greek yogurt, mayonnaise, lime juice, chili powder, paprika, and salt.
In a large bowl mix the pasta, corn, red bell pepper, red onion, cilantro, and cotija cheese.
Add dressing to the pasta salad and mix. Serve immediately or store in the fridge for later! If you are making this more than 3-4 hours ahead of time, wait to add the dressing until before serving, as this will make the dish creamier because the pasta will not soak up as much of the dressing beforehand.
