For his NASA career, Sjoberg joined the Space Task Group in 1959. With the task group, Sjoberg worked on Project Mercury until the early 1960s. During this time period, Sjoberg began his thirteen-year flight operations experience when he joined the Langley Research Center in 1959.
After completing his four-year coordinator tenure at Langley, Sjoberg started out as an assistant for the Manned Spacecraft Center in 1962. While at the flight operations department for the MSC, Sjoberg was their deputy director from 1963 to 1969 before becoming their flight operations director at the end of 1969. During his tenure, Sjoberg was part of the operations team when the Apollo 13 accident occurred in 1970. By 1972, Sjoberg had worked on Project Gemini and multiple spaceflights of Project Apollo.
That year, Sjoberg became the deputy director for the MSC and took over Christopher C. Kraft Jr.'s position. In 1973, the Manned Spacecraft Center was renamed to the Lyndon B. Johnson Space Center. While Skylab and the Apollo Soyuz Test Project were undergoing throughout the 1970s, Sjoberg continued to be part of Project Apollo. Sjoberg remained as deputy director until he ended his NASA career in 1979. That year, Sjoberg became the director of OAO Corporation for their Houston branch.

## Awards and honors
