To get involved in open source projects, start by using Linux and open source software to find what interests you. Research projects in your area of interest and contact their teams to see if you have the required skills or can learn them. Choose a junior role on a project and get involved in the community. To be successfully employed, take a top-down approach by researching in-demand profiles and skills rather than assuming certification means you're fully qualified. Learn the skills required for the profiles that are in high demand.
