Linder’s first venture after graduation was Euro-Imports, which specialized in distribution of lightweight racing bicycles from overseas and sponsored several teams and events on the nascent American racing circuit. In 1980 Linder segued to building and "selling high-technology, lightweight wheelchairs through his Quadra Medical Corporation." Quadra's models featured "aircraft alloy frames...wheel hubs frictionized coated adjustable back height." The development and production of the feature filmThe Running Man was Linder’s first experience as a film producer. As multiple commentators have recounted, Linder discovered the novel written by Stephen King under the pseudonym Richard Bachman, optioned the film rights, and wrote the first draft of the screenplay. Once the project was green-lit by TriStar/Columbia and other companies, Linder’s work as producer included the above-the-line decisions in particular the casting of fellow Austrian Arnold Schwarzegger as the lead characterBen Richards. To underscore the parallel between the futuristic world of the movie and the actual events of World War II, Linder introduced the actor to his father Bert, the holocaust survivor. In 2019 Linder was interviewed by the New York Post for an article highlighting how 1980s science fiction anticipated many aspects of today's reality, where he pointed out that “the lines have blurred between reality and news and propaganda and entertainment” and the influence of pervasive reality shows, an alumnus of which is now chief executive. During the same period, Linder partnered with writer/director Richard Rothstein on several projects. Together they developed the idea for the Universal Soldier series of films and the pilotBates Motel, which Universal aired as a television movie. Other projects that Linder has developed include Midnight Graffiti for Peter Guber at Mandalay Entertainment and Club Fed for Bill Mechanic at Pandemonium. In 2002 Linder was Executive Producer of the Austrian feature She Me and Her. Shortly thereafter Linder became a partner with writer/producer/director Alain Silver in Untitled LLC. Their initial project was Nightcomer. Untitled was also a production company on Radio Mary.
