Mechanical Engineer cover letter example

Hiring managers skim a mechanical engineer cover letter for one thing: proof you can do this job, in their words. Below is a short letter that does exactly that. Replace the bracketed parts and the results with yours.

Dear Hiring Manager,

I'm applying for the Mechanical Engineer role at [Company]. My background in one line: mechanical engineer with 6 years designing industrial equipment.

Two results from my last roles that match what you're asking for:
- Redesigned a pump housing for casting, cutting unit cost by 22% on 8,000 units a year.
- Took a new mixer line from prototype to production in 10 months, 2 months ahead of plan.

I also ran FEA on load-bearing parts, removing 15% of material with no loss of safety margin. Day to day I work with SolidWorks, FEA, GD&T and DFM, which your posting lists among the core requirements.

I'd welcome a short call to walk through how I'd approach [a priority from the job ad] in the first 90 days.

Best regards,
Lukas Weber

Why this letter works

It is short. Under 200 words: it gets read to the end.
Results, not duties. Both proof points carry a number a recruiter can repeat to the team.
It mirrors the posting. SolidWorks, FEA, GD&T, DFM are the words mechanical engineer ads use; swap in the exact terms from yours.
It asks for a next step tied to their priorities, not a generic "hope to hear from you".

Mistakes that get mechanical engineer cover letters skipped
