Dear Jane Smith,
I am writing to express my interest in the Software Tester position at Tech Innovations Inc. as advertised on indeed.com.

During my internship, I developed test cases for web applications, executed manual and automated tests, and documented defects using JIRA. One of my significant contributions was identifying a critical bug that impacted the user experience, leading to a swift resolution before the product release. My academic background, combined with hands-on experience, has equipped me with a solid understanding of software development life cycles and testing methodologies.
I am particularly impressed by Tech Innovations Inc.’s commitment to delivering high-quality software solutions. I believe my attention to detail and passion for quality assurance would align well with your team’s values. I am eager to contribute my skills and grow professionally in your innovative environment.
Thank you for considering my application. I look forward to the opportunity to discuss how I can be a valuable addition to your team.
