If you're interested in systems programming, I'd learn Go (http://golang.org http://golang.org). The team behind Go (which includes Ken Thompson and Rob Pike) is very strong technically, and there's a lot to learn about programming style and techniques for any language by reading the source code to the standard Go packages (http://golang.org/pkg/ http://golang.org/pkg/). However, Go is still very young and being actively developed so it's probably premature to add as a marketable skill to your resume.
