How to write a Linux system administrator cover letter

You can follow these steps to draft an effective cover letter for a Linux system administrator role:

1. Include your contact information

Create a header to include your contact details on your cover letter. A header is usually at the top of the letter and contains your full name, professional e-mail address, phone number, city, and province or territory. Ensure you provide accurate information in this section to allow hiring managers to contact you if they have further clarifications or intend to schedule an interview.

You can also add the date you're applying to assure the hiring manager your application is recent and valid. Below the date, mention the company name and location to confirm you're sending your application to the right organization.

2. Greet the recipient

You can use a professional greeting to address the recipient of the letter. In many cases, the recipient is the hiring manager who reviews the candidates applying to the company. Address them with a professional greeting, such as Dear, followed by their full name. Consider browsing the company website to get information on the hiring manager's name. If you can't find their full name, you can greet them with only their last name.

For example, Dear Ms. Stone or Dear Mr. Brown are standard greetings for a cover letter. If you can't find any information on who to address on your cover letter, consider using a generic greeting like Dear Hiring Manager.
