Niedermeyer began his coaching career in 2012 as a student assistant at the University of Arkansas at Pine Bluff, studying defense.
The following year, Niedermeyer took on a volunteer analyst role under linebackers coach Michael Barrow for the Miami Hurricanes football program.[1]
In 2014, Niedermeyer started his first position coach role for East Texas Baptist University as the wide receivers coach. He coached the group to becoming the top passing offense in NCAA Division III that year.[1]
In 2015, Niedermeyer joined the University of Georgia football program as a graduate assistant. There, he worked predominantly with the linebackers group, helping coach and develop Leonard Floyd, Jordan Jenkins, and Roquan Smith.
Niedermeyer then joined the University of Alabama football program, again as a graduate assistant. He worked under then-defensive coordinator Jeremy Pruitt, who would eventually become the head coach of the University of Tennessee. Niedermeyer got promoted to assistant director of recruiting operations in 2017, while also helping coach and develop future professional players Reuben Foster, Tim Williams, and Ryan Anderson.[1]
In December 2017, Pruitt was hired as the head coach of the University of Tennessee Volunteers football program.[2] He hired Niedermeyer as the tight ends coach for the Vols.[3] Niedermeyer quickly went to work recruiting and signing the then nation's No.1 junior college tight end, Dominic Wood-Anderson.[4] Niedermeyer continued his recruiting momentum for the 2018 season by signing multiple top players in the class including Darnell Wright, Quavaris Crouch, and Henry To'oto'o. His efforts earned him the 2019 National Recruiter of the Year by sports media outlets 247Sports.com and ESPN.[5][6]
In January of 2021, Niedermeyer, along with most of the coaching staff at the University of Tennessee, were fired after an internal investigation. Niedermeyer was one of only two assistant coaches who had been with Tennessee football since Pruitt was hired.[7] There were allegations that coaches put money into McDonald's bags and gave them to the recruits when they came on campus.[8]
In 2021, Niedermeyer was named an assistant coach for St. Thomas Aquinas High School.
After one year Niedermeyer was named defensive coordinator for IMG Academy.[9]
In 2024, Niedermeyer took the same position for Tuscaloosa County High School.[10] On December 10, 2024, Niedermeyer was promoted to the head coaching position at Tuscaloosa County High School.[11]
On March 5, 2025, Niedermeyer was hired by the Denver Broncos as a defensive quality control coach; his first coaching position at the professional level.[12]
