Lorem ipsum

In the following writing guide, you'll find more details on how to tailor your letter to your target application engineer role.

PRO TIP

Addressing your letter's recipient by name is a sure way to show your attention to detail. Avoid generic greetings such as “To Whom It May Concern.“ Check out more appropriate greeting options in our guide for addressing a cover letter without a name.

STEP 2

Introduce yourself in the opening paragraph

How you open your cover letter shapes your first impression on hiring managers. Start strong by highlighting your relevant skills and qualifications, and express your enthusiasm for the specific application engineer role.

PRO TIP

If a current employee has referred you for this position, mention this in the opening paragraph. Our referral cover letter openings article shows you how to do this.

STEP 3

Share relevant achievements in the body paragraph

Your cover letter's body paragraph should include unique achievements you didn't already mention on your resume. There's so much you can do with this section: share your long-term career goals, share anecdotes demonstrating your work ethic or commitment to the job, or narrate the story of your career growth so far.

By collaborating closely with cross-functional teams, I implemented solutions that enhanced application performance and reliability, leading to a 40% decrease in downtime. This success stems from my dedication to innovation and efficiency, qualities that I am eager to bring to your organization to drive impactful results.

I'm confident I can adapt if given the chance.

STEP 4

Finish by encouraging next steps
