Dear Hiring Manager,
I am writing to apply for the position of Commercial Software Engineer. With my experience developing and testing software applications, I believe I am well-suited to help your team produce high-quality products.
My experience in software engineering started five years ago when I joined a local start-up as a Junior Software Engineer. During my time there, I helped launch several products which have become popular choices amongst customers. This experience instilled in me the importance of staying up to date with current technologies and trends, and also introduced me to the principles of object-oriented programming that I continue to use today.
I have since gone on to work as a Senior Software Engineer at a larger software company. During this time I worked with multiple development teams and contributed to the successful delivery of projects. My experience has allowed me to develop strong problem solving and debugging skills, along with excellent communication abilities when it comes to troubleshooting technical issues.
Finally, I have an impressive track record in developing high-quality software applications, and am adept at delivering projects on time and within budget. My experience has provided me with a deep understanding of the software development cycle, from concept to completion.
I look forward to discussing my qualifications further during an interview and thank you for your consideration.
Sincerely,
Name
(Your Signature)
