Bring a large pot of salted water to a boil. Add pasta and cook al dente according to the package instructions. Drain the pasta, then rinse with cold water to stop the cooking process. Set aside.
In a medium bowl, combine the diced chicken, garlic powder, paprika, salt, and pepper. Toss until the chicken is evenly coated.
To a large, nonstick skillet over medium heat, add olive oil. Once hot, add the seasoned chicken. Cook, stirring occasionally, until golden brown and fully cooked to an internal temperature of 165°F, about 6–8 minutes. Remove the skillet from the heat and allow the chicken to cool completely.
In a small bowl, whisk together the mayonnaise, sriracha, and lime juice until smooth and creamy. Set aside.
In a large mixing bowl, combine the cooked pasta, chicken, bell pepper, corn kernels, and parmesan.
Pour the sriracha mayonnaise sauce over the pasta mixture. Toss everything together until evenly coated.
Serve immediately. Or, cover the bowl and refrigerate to let the flavors develop until ready to serve.
Before serving, garnish with chopped fresh cilantro.
