Mechanical Engineer · cover letter
[Date]
Dear [Hiring Manager],
When the [Company] posting called for a mechanical engineer who owns parts from concept through tooling, it described the work I have been doing for the last four years. In my current role I redesigned a die-cast aluminum housing in SolidWorks, switching to a ribbed thin-wall structure that cut part weight by 22 percent and trimmed material cost by $1.40 per unit. Across an annual volume of 90,000 units, that change returned roughly $126,000 a year without missing a single sealing or vibration spec.
Most of my day is spent where design meets manufacturing. I run GD&T tolerance stack-ups before release, build DFM reviews with suppliers, and validate parts against thermal and fatigue requirements using FEA. I am comfortable defending a design decision in a drawing review and just as comfortable reworking it when test data disagrees with me.
What draws me to [Company] is that you build hardware people actually depend on, which means tolerances and reliability are not negotiable. That is the environment where I do my best work, and where I can shorten the path from prototype to production tooling.
I would welcome the chance to walk through my design portfolio and talk about the problems your team is solving next. Thank you for your time and consideration.
Sincerely,
[Your Name]
