Learning first, build up your knowledge, practice more to get more skills, more experiences. Building your trust, try to be more helpful by be ready to help others when they need help and you can help them.
Over time, you will find your jobs in bitcointalk forum. At the moment, honestly I don't think you can find any job there (regardless of signature campaigns, bounties, translations, airdrops), but I don't recommend you to focus on those things. Learning is first priority of newbies (and Junior members); should be the first.
