1) First thing is to build a resume. Recognize that you will probably not crank out a perfect resume in one sitting. Regard your resume as a living, evolving document and in the back of your mind be thinking of how to make incremental improvements. If necessary, get professional help from reputable outfits such as JobScan to get you started.
2) Once you have a decent resume (doesn't have to be the final, perfect version!), start your search on Indeed.com, glassdoor.com, which are the best job boards. You can set up daily or weekly email alerts which deliver to your inbox lists of new jobs as they become available. Wherever possible, apply through the job board, or directly on the company website. Avoid dealing with 'headhunters' who scavenge from these sites, because they make a living by taking a cut of your initial salary.
3) Join LinkedIn if you haven't already. Invest effort to build the best profile you can that shows off your education, skills, and practical ability. Include a nice portrait photo of yourself. Like the resume, the profile is an evolving document. As you build it incrementally, you can can update your resume, and vice versa. Build your network. Connect on LinkedIn with people who have the jobs you want to get. Send them an introductory message telling them who you are and why you would like to connect. Don't be afraid to ask, people are usually quite willing to connect. Connect also with 'talent acquisition' recruiters that work in this sector. LinkedIn will also suggest jobs that are consistent with your profile.
4) Join meetups of other people who share common interests in your field.
Good luck, I hope you will find a job soon!
