Mechanical Engineer cover letter example
Dear Hiring Manager,
I'm applying for the Mechanical Engineer position at [Company]. I design mechanical systems that work reliably in the real world, and your work in [industry/product] is exactly the kind of engineering I want to do.
In my current role I design components and systems from concept through production. One assembly I redesigned reduced manufacturing cost by 18% while improving durability, and I cut a product's development cycle by two months through better DFM practices. I'm proficient in SolidWorks and [tools from posting], experienced with GD&T and tolerance analysis, and I collaborate closely with manufacturing to make sure designs are actually buildable.
I'd welcome the chance to bring that practical, results-oriented approach to [Company].
Sincerely,
[Your Name]

Frequently asked questions
What should a mechanical engineer cover letter include?
A design project with measurable results (cost, durability, cycle time), CAD and analysis tools, and evidence you design for manufacturability.
How do new grad engineers write one?
Lead with senior design projects, internships, and CAD skills. Quantify anything you can and show hands-on, buildable thinking.
Should I mention specific software?
Yes. SolidWorks, CATIA, ANSYS, and similar tools are keywords. Name the ones in the posting that you know.
