A mechanical engineering cover letter is often the first thing a hiring manager reads about you, and for students and new graduates competing for internships and co-op positions, it carries more weight than a short resume. This guide is written for undergraduate and graduate ME students, recent graduates, and early-career engineers preparing their first professional applications. It covers what recruiters look for, how to frame academic work as real evidence, and how to write a letter that earns an interview. For a foundational framework that applies to any field, see our complete guide on how to write a cover letter.
What employers look for in a mechanical engineering cover letter
Recruiters reviewing mechanical engineering applications for internships, co-ops, and entry-level roles are not screening for years of professional experience. They are evaluating whether a candidate has the technical foundation to contribute quickly and the communication skills to function on an engineering team. Here is what carries the most weight:
- Relevant coursework and projects. Thermodynamics, fluid mechanics, machine design, controls, and materials science demonstrate domain knowledge when paid experience is limited. Name the courses and describe what you built or analyzed.
- CAD and simulation software. SolidWorks, AutoCAD, ANSYS, MATLAB, and LabVIEW are commonly required. Mention the tools you have used even in a lab or classroom context, and describe what you did with them.
- Lab and hands-on experience. Fabrication work, university machine shop access, senior design prototyping, or a student project team such as SAE, Formula SAE, or ASME shows you can work with physical systems, not just models.
- Quantified outcomes. Even modest metrics — a percentage improvement in simulated efficiency, a reduction in prototype weight, or hours logged in a testing environment — build credibility.
- Collaboration and professional judgment. Mechanical engineers work alongside other disciplines. An example of coordinating within a team or presenting a technical trade-off to an advisor demonstrates readiness for a professional setting.
How to write a mechanical engineering cover letter that gets interviews
1. Open with a technical result, not a generic introduction
Avoid leading with "I am writing to apply for." Instead, anchor your first sentence to a concrete outcome from your most relevant experience — a metric from your senior capstone, a simulation result from a controls lab, or a design decision you made on a student project. Recruiters read dozens of letters; a specific technical claim in the first line signals that the rest of the letter is worth reading. For a parallel approach applied to professional roles, see the mechanical engineer cover letter.
2. Match your technical vocabulary to the job posting
Read the description carefully and identify the two or three skills most emphasized. If the posting highlights thermal analysis, reference your heat transfer coursework or a specific ANSYS simulation you ran. If it focuses on product development, draw on any DFM or tolerance analysis work from your machine design course or senior project. This targeted alignment also helps with applicant tracking systems that screen for keyword matches before a human reviewer sees your letter. For a broader view of how this applies across the discipline cluster, see the engineering cover letter guide.
3. Frame academic experience as professional evidence
Students often discount their own qualifications because they lack paid work history. Treat your senior design project as a real engineering engagement: describe the problem statement, your role on the team, the tools and methods you used, and the outcome. A well-described capstone project is more persuasive than a vague reference to a summer job unrelated to engineering. For additional strategies on presenting academic work, our internship cover letter guide covers framing approaches that apply directly to ME students.
4. Close with a firm-specific reason and a clear next step
Generic closings such as "I look forward to hearing from you" waste the final impression your letter makes. End by naming something specific about the company — a product line, a market they serve, a technology they are known for — and connect it to your own interests or goals. Then propose a direct next step: a brief phone call or an interview at their convenience. Browse the Engineering & Tech section for related letter guides across the discipline.

Before you send your application
Use this checklist to catch common mistakes before submitting your mechanical engineering cover letter:
- You have named at least two specific tools, courses, or projects rather than relying on phrases like "strong technical background" or "passion for engineering."
- At least one claim includes a number — a percentage, a scope, a duration, or a measurable outcome from a project or lab.
- The letter references the company by name and identifies something specific about why you are targeting them.
- Your language mirrors terms from the job posting, such as "thermal management," "DFM," "FEA," "product lifecycle," or "prototyping," wherever those terms apply to your experience.
- The letter is one page, written in a professional tone, and free of spelling or formatting errors.
- If you are applying for a co-op or internship, review our internship cover letter guide for additional advice on framing academic experience in a competitive application.
FAQ
How long should a mechanical engineering cover letter be?
Keep it to one page, roughly 250 to 350 words in the body. Three focused paragraphs covering your technical background, a specific project or lab result, and your interest in the company are sufficient. Recruiters at engineering firms and manufacturers move quickly during initial screening, so front-load your strongest technical evidence rather than saving it for the middle of the letter.
What should I include in a mechanical engineering cover letter with no work experience?
Focus on senior design projects, course labs, simulation work, and student organizations like Formula SAE, ASME, or a robotics team. Describe the problem you were solving, the tools you used, and the outcome or what you learned. Co-op positions, paid or unpaid research assistantships, and university fabrication work also qualify as legitimate engineering experience and should be treated as such.
Should I mention CAD and simulation software in my cover letter?
Yes, especially when the job posting lists specific tools as requirements. Name the software and explain the context: a senior project, a course assignment, or a lab exercise. Simply listing SolidWorks or ANSYS without any context is less persuasive than describing a specific design or analysis task you completed using those tools.
How is a mechanical engineering cover letter different from a mechanical engineer cover letter?
The mechanical engineer cover letter is typically aimed at licensed or experienced professionals pursuing mid-level or senior engineering roles. A mechanical engineering cover letter more often targets students, co-op applicants, and recent graduates who are in or just completing an undergraduate or graduate ME program. The evidence you draw on — academic projects, coursework, and student teams — differs accordingly, as does the framing around career goals and professional development.
Do I need a cover letter for a mechanical engineering co-op or internship?
Yes. Most co-op and internship programs require one, and submitting a strong letter even when it is listed as optional demonstrates initiative and genuine interest. Use the letter to explain why you are interested in this company's specific technology or product area, since that level of detail is difficult to convey in a resume alone.
