Some applications require a cover letter, for others it's optional. Even if it's optional, I would still always include one. It's a great opportunity to show a company more about your skillset, your experience and that you're a great match. It also shows that you really care about the opportunity, and that you are willing to put some effort in your application.
Start with 2-3 sentences as an Intro. Make a small teaser about you, how you found out about the opportunity and why you're applying.
In the next paragraph you can write more about your previous work experience, highlight some of your skills and also mention which impact you made in previous jobs.
Highlight your transferable skills from previous jobs or education. Mention projects and/or skills you worked on in your free time. Describe how you get excited about learning new things, and your ability to process new information easy and fast.
After you gave some insight into your work experience, you should explain what you like about the job opportunity, the company and how you can add value to them. Mention what you bring to the table and what you think you can learn from them.
Finish your cover letter and mention that you would be happy about the opportunity to introduce yourself in an interview.
Make sure your Cover Letter and CV work well together. Use a similar style, same fonts etc.
