There are a lot of opportunities coming up in the near future. Recession is receding and there are a lot of small startups where you can easily spend your coming 4-6 years.
Once you finish reading the `Understanding the linux kernel’ book and
work on attaching S3 and EBS as a VFS and learn more about page cache and how the linux kernel works in depth and about networking in general, you will be able to take up any job in the market. You will be complete in that respect with total knowledge of all the necessary fields.
Meanwhile, you will also be practicing programming in Java using acm.icpc problems and that will really hone your programming skills.
Once that is done, you can join Twitter or Palantir Technologies or worst case join AWS because you will be good in Infrastructure anyways.
Now, there you go, your future is great!
