The movie doesn't do the book justice. In the book Nedry leads an on-shore team of developers, implied to be high-end competence based in Cambridge. The reason he is the only one on-site is because InGen don't want knowledge about the dinosaurs to leak before they launch the park, so the team basically develops from false or deficient premises and Nedry is the one who can compensate for this.

Nedry is a contractor and presumably reasonably payed, but the job would be awful regardless of how much money he'd make. He's alone, the rest of the on-site employees regard his technical wizardry with deep suspicion and his work habits with disgust. His boss, Hammond, can't stop himself from interfering. Dodgson gives him a way out, in the form of a large cash payment at an airport.

In the book Hammond is a truly ruthless businessman and it makes quite decent satire of the character. When he says things like 'no expense spared' or 'I like kids' it's more like it's coming from an Elon Musk on a stim bender than the warm and aloof Hammond of the movie. In the book, when Hammond comes under pressure he reacts with rage, like when they've realised that Nedry is gone and that Arnold will have to go through the source code himself. At that point Hammond is screaming expletives at his employees, who calmly respond that he instead should go to the cafeteria and get a coffee.

It should also be added that according to the book the reason the park fails is not because it has a single point of failure, but that it is a complex system and inherently uncontrollable. To some extent this shows in the Malcolm character in the movie as well but they do very little with this except having him deliver a few one-liners and the chaos talk with the water drops early on.
