Key Elements of a Strong Cover Letter
Start with your name, phone number, email, and LinkedIn or GitHub if relevant. Include the employer name, role title, and date so the reader knows this letter is tailored to the internship.
Begin with a specific reason you want this internship and an achievement that proves your fit. This grabs attention and shows you are not sending a generic letter.
Describe two or three technical skills, lab techniques, or class projects that match the internship description. Use concise examples that show what you did, the tools you used, and the outcome you helped produce.
End with a polite request for an interview and a brief restatement of your enthusiasm. Thank the reader and note your availability for next steps.
Cover Letter Structure
1. Header
Place your name at the top in a clear font followed by your contact details. Below that, list the company name, internship title, and the date to show the letter is specific to this role.
2. Greeting
Address the letter to a named person when possible, such as the hiring manager or lab supervisor. If you cannot find a name, use a professional greeting that refers to the hiring team.
3. Opening Paragraph
Start with a short sentence that states the internship you are applying for and where you found it. Follow with a one sentence hook that highlights a relevant accomplishment or interest that ties you to the role.
4. Body Paragraph(s)
Write one to two short paragraphs that connect your coursework, lab work, and technical skills to the internship requirements. Give a concrete example of a project or experiment, mention the tools or techniques you used, and explain the result or what you learned.
5. Closing Paragraph
Finish with a concise paragraph that reiterates your enthusiasm and how you will contribute during the internship. Politely ask for the opportunity to discuss your application and provide your availability for an interview.
6. Signature
Use a formal closing such as "Sincerely" followed by your typed name. If you include a digital signature, make sure contact details remain visible below your name.
Dos and Don'ts
Do tailor each letter to the specific lab or company by referencing a project, publication, or product that interests you. This shows genuine interest and helps your application stand out.
Do highlight measurable or specific outcomes from class projects, research, or internships, such as improving a protocol, reducing error, or building a prototype. Concrete results help hiring managers understand your impact.
Do name the tools and techniques you know, for example CAD software, PCR, cell culture, or MATLAB, and tie them to the tasks in the job posting. This helps match your skills to the role quickly.
Do keep the letter to one page and use clear, simple sentences so the reader can scan your qualifications. Short paragraphs make it easier to find your most relevant points.
Do proofread for grammar, correct technical terms, and accurate contact details before submitting your application. A polished letter reflects attention to detail that is valued in engineering roles.
Don’t send a generic cover letter that names a different company or role, because that signals a lack of care. Always update the company name and role title before sending.
Don’t repeat your entire resume line by line, because the letter should add context to your most relevant experiences. Use the letter to explain why a single project or skill matters for this internship.
Don’t overclaim responsibilities or outcomes that you did not achieve, because credibility matters in technical fields. Be honest about your level of contribution and what you learned.
Don’t use vague buzzwords without examples, because those phrases do not prove capability. Replace general terms with specific tasks, methods, or software you used.
Don’t include irrelevant personal information or long career histories that distract from your fit for the internship. Keep the focus on what matters for this role.
Common Mistakes to Avoid
Failing to connect your academic work to the internship tasks can make your letter seem unrelated. Show how a lab project or course prepared you for a specific responsibility listed in the posting.
Using overly technical language without context can confuse nontechnical HR readers who screen applications first. Explain technical terms briefly or show the outcome in plain language.
Writing excessively long paragraphs makes it hard to scan your qualifications quickly. Break content into short paragraphs of two to three sentences to improve readability.
Neglecting a clear call to action leaves the reader unsure how you want to proceed. Close by asking for an interview and noting your availability to make the next step easy.
Practical Writing Tips & Customization Guide
If you have a short portfolio, link to a GitHub repo or lab poster to give the reader quick access to evidence of your work. Label the link clearly so reviewers know what they will see.
Mirror language from the internship posting when it honestly fits your skills to help applicant tracking systems and human readers see the match. Use exact phrases for techniques or tools listed in the job description.
If you can, mention a mutual contact or a recent paper from the lab to show familiarity and genuine interest. That detail can help your application feel more personal and informed.
Prepare a one minute verbal summary of the same achievements in case you get a preliminary phone screen. Being able to speak clearly about your projects boosts confidence in interviews.
Cover Letter Examples
Example 1 — Recent Graduate (Industry Focus)
Dear Dr.
I am a recent B. S.
biomedical engineering graduate from University X (GPA 3. 7) applying for the Summer Device Development Internship.
In my senior capstone, I led a 4-member team that designed a portable infusion pump; I modeled fluid dynamics in MATLAB and reduced predicted flow error from 6% to 2% through calibration changes. During a 12-week hospital lab rotation I validated sensors on 30 patient trials and documented protocols that cut test time by 25%.
I am proficient in SolidWorks, Python, and bench testing with oscilloscopes and am familiar with ISO 13485 documentation.
I admire MedDevices Co. ’s focus on wearable monitors and would like to contribute to your next-generation pressure-sensing project.
I can start May 15 and am available for a 12-week placement.
Sincerely, Alex Rivera
Why this works:
- •Starts with concrete credential (GPA, timeline).
- •Quantifies impact (6%→2%, 25% time reduction).
- •Ties skills to the company project and gives availability.
Example 2 — Career Changer (Mechanical Engineer to Biomedical Intern)
Dear Hiring Manager,
With five years as a mechanical design engineer at AeroParts Inc. , I am transitioning to biomedical work and seek your R&D internship to apply my prototyping and DFMEA experience.
I led design iterations of a nozzle assembly using SolidWorks and reduced assembly time by 40% through tolerance redesigns and jigs. Last year I completed an online course in biomaterials and volunteered on a community prosthetic project where I 3D-printed socket prototypes and improved patient comfort scores by 15% in follow-up surveys (n=20).
My strengths include rapid prototyping, GD&T, and documenting design controls; I also have hands-on experience with 3D printers and tensile testing rigs. I am eager to translate my manufacturing-first mindset to medical device reliability testing at BioEquip Labs and can begin part-time immediately.
Best, Maya Thompson

- •Ends with a concise call to action (specific availability and meeting length).
Writing Tips
1. Open with a specific hook.
Mention the role, team, or product you want to work on in the first sentence to show you read the posting and to capture attention.
2. Quantify achievements.
Use numbers (e. g.
, reduced test time 25%, supervised 2 techs, $12k budget) so hiring managers can compare impact across candidates.
3. Match 3–5 keywords from the job description.
Mirror terminology for tools, standards, and skills (e. g.
, ISO 13485, SolidWorks, bench testing) to pass quick scans and applicant tracking.
4. Keep paragraphs short and focused.
Limit to 3–4 brief paragraphs: intro, 1–2 skill-impact examples, and a closing with availability. That fits one page and aids skim readers.
5. Show one transferable story if you lack direct experience.
Describe a project where you used similar methods (e. g.
, CAD/prototyping) and give measurable results.
6. Use active verbs and specific tools.
Say “designed tolerance revisions in SolidWorks” rather than vague phrasing; it reads stronger and clearer.
7. Address company fit briefly.
Cite a product, published paper, or recent press and explain in one sentence why you’re excited to help.
8. Close with a concise call to action.
State availability and propose a 15–30 minute call to make it easy for the recruiter to respond.
9. Proofread with a checklist.
Verify names, numbers, and acronyms; read aloud and have one technical peer check for accuracy.
Customization Guide: Industry, Company Size, and Job Level
Strategy 1 — Industry emphasis

- •Finance (health-tech partnerships, reimbursement): Highlight cost models, ROI analysis, and stakeholder communication. Example: “Built a cost-per-patient model projecting break-even in 18 months at 10k units/year.”
- •Healthcare (clinical devices, hospitals): Prioritize regulatory familiarity (ISO 13485, 21 CFR), clinical trial experience, and patient-facing testing. Example: “Assisted in a pilot with 30 patients and contributed to an IRB submission.”
Strategy 2 — Company size and tone
- •Startups: Use a results-oriented, flexible tone. Stress rapid iteration, multitasking, and willingness to wear multiple hats; show one example of shipping a prototype in <3 months.
- •Large corporations: Be structured and compliance-aware. Emphasize standard processes, cross-functional coordination, and documentation experience (change control, design history files).
Strategy 3 — Job level adjustments
- •Entry-level/Intern: Focus on coursework, capstones, lab techniques, and measurable lab outcomes. Offer availability and a willingness to learn specific tools used by the team.
- •Senior/Lead roles: Highlight team leadership, budget ownership, and product milestones (e.g., led a team of 6 to launch Class II device with 95% on-time verification).
Strategy 4 — Concrete customization steps (apply these in order)
1. Read the job posting and company site; list 5 top skills they require.
2. Select 2–3 projects from your experience that map directly to those skills and quantify the outcomes.
3. Tailor your opening sentence to reference the team or product and your closing to state specific availability or a proposed next step.
Actionable takeaway: For every application, swap in 3 targeted lines—one in the opener, one in the middle example, and one in the closing—to reflect industry, company size, and job level.
