Find a company that is as less ambitious as you. A lot of "work load" in traditional tech sector businesses comes from either the ambitions of the company or ambitions of the higher-ups (nothing wrong with either btw). There are plenty of non-sexy, service-sector, small businesses out there that wouldn't mind having a dependable IT resource. But even if you found somebody like this, I wouldn't be forthright with this motive. Nobody would hire a self-professed slacker.
