Amazon’s longtime head of film and television, Jennifer Salke, is stepping down from her position after seven years on the job, the company said on Thursday, a sudden move that shakes up the top ranks of the streaming giant.

Ms. Salke will move into a producing deal at Amazon and will not be replaced, Mike Hopkins, head of Prime Video and Amazon MGM Studios, said in a staff memo. Instead, he added, he has decided to operate distinct film and television studios. Courtenay Valenti will continue to oversee film while Vernon Sanders will remain atop television.

“Jen has decided that her next challenge and chapter will be on the production side, with the aim of getting even closer to the global creative community,” Mr. Hopkins wrote.

Known as a combative number cruncher and familiarly known as Jay, Mr. Goldin was first elected comptroller in 1973, the same year that Abraham D. Beame, who had been comptroller,66jogo was elected mayor. Mr. Beame was ousted after one term as the city neared insolvency, a key factor in Mr. Koch’s successful race to succeed him in 1977.

The change shocked many employees inside the studio, including one group busy putting the finishing touches on Amazon’s presentation at the year’s biggest theater convention, CinemaCon, which will be held next week. Ms. Salke was set to introduce the company’s robust slate of coming films.

She was also featured this month at the SXSW Film & TV Festival, where she and Ms. Valenti were interviewed by Charles Rivkin, the head of the Motion Picture Association. At the event, Ms. Salke tried to dispel a rumor that constantly dogs executives at Amazon — that every creative decision is determined solely by data.

“Creative conviction really rules the day,” she said. “But you have to be right a lot.”

“Luckily,” she added, “we’ve had some good examples of it working, and so people listen to the gut, and I guess we’ll be here as long as our gut leads us mostly in the right direction.”
