Designing, building, launching and operating missions like Kepler and TESS require many different skillsets and specialties, from electrical, mechanical, thermal and systems engineers (to name a few), scientists and astronomers, to management, finance personnel and artists. It takes a veritable army to pull off these amazing projects. It is also advantageous to be multi-disciplinary: my educational background is in electrical engineering with specializations in image and signal processing, and in mathematics. I applied myself first to remote sensing of planetary atmospheres, and then to the problem of detecting weak transiting planet signatures against stellar and instrumental noise. Having a strong engineering and mathematics background as well as being a scientist and astronomer has positioned me to make critical contributions to Kepler and TESS. Many paths can lead to a career with NASA and in space science. Look for internship opportunities at NASA centers and look for universities with professors doing research for NASA that fascinates you.
