How to write a cover letter (US job search)

A strong cover letter template is not a generic essay — it is a short pitch aligned with one job posting. Start with the exact job title, mirror important keywords from the job description, and prove fit with one measurable achievement. US recruiters scan quickly; lead with relevance in the first two sentences.

Recommended cover letter structure

  1. Opening: Role + why you are a credible match (not “I am writing to apply…”).
  2. Proof: One or two wins with outcomes (revenue, time saved, users, quality metrics).
  3. Company signal: Show you researched the employer (product, customers, values).
  4. Close: Confident next step — interview availability, not desperation.

ATS-friendly cover letter tips

  • Use plain text or simple PDF — avoid columns, icons, and text inside images.
  • Spell the company name and job title exactly as in the posting.
  • Include hard skills the posting mentions when you truly have them.
  • Keep file names professional, e.g. FirstName-LastName-Cover-Letter.pdf.

Our AI cover letter builder is designed for this workflow: you supply accurate facts, the tool drafts an ATS cover letter aligned to the posting, and you edit before sending. Pair it with a focused resume and apply through US job listings on Vaga Certa.

Cover letter example (software engineer)

Illustrative sample — hook, proof, company signal, close (~280 words)

Dear Hiring Manager,

When I came across Stripe's opening for a Senior Software Engineer, I immediately recognized the scale of the infrastructure challenges your payments platform faces daily — and how directly my background in distributed systems aligns with what your team needs.

Over the past five years at Plaid, I've built and maintained high-availability APIs processing over $2B in annual transaction volume. Most recently, I reduced our payment failure rate by 34% by redesigning our retry logic with exponential backoff, and cut p99 latency from 420ms to 180ms through strategic caching at the API gateway layer. I'm fluent in Go and TypeScript, and I've led migrations of legacy monoliths to microservices architecture for three teams.

Stripe's mission to increase the GDP of the internet is something I genuinely believe in. The way your team approaches developer experience — making complex financial infrastructure feel simple — is exactly the kind of challenge I want to work on. I've followed your engineering blog for years, and the recent post on your incremental migration to Sorbet reinforced that Stripe invests deeply in code quality and long-term maintainability.

I'd love to bring my experience in high-throughput financial systems to your team. I'm available for a call anytime this week — please feel free to reach out.

Best regards,

Cover letter FAQ

What is a cover letter?

A cover letter is a one-page document sent with your resume. It introduces you, explains fit for the role, and highlights proof hiring managers care about. Many recruiters and hiring managers still read cover letters — especially when they are short, specific, and aligned with the job posting.

How long should a cover letter be?

Aim for 250–400 words (about three to four short paragraphs). Busy hiring teams prefer concise letters with clear impact and keywords from the job description — not long essays.

How do I write an ATS-friendly cover letter?

Use the job title and key skills from the posting in natural sentences, plain formatting, and standard fonts. Avoid text boxes, images, and unusual symbols. Save as PDF when the employer allows — our builder outputs clean text you can export as PDF.

Should I address the hiring manager by name?

When you are sure of the name and spelling, a personalized greeting helps. If you are not sure, “Dear Hiring Manager,” is widely accepted. Avoid “To Whom It May Concern.”

What is the best cover letter format for US jobs?

Lead with relevance to the role, then proof (achievements with outcomes), then a line showing you researched the company, and close with a confident, polite call to follow up. Problem–solution framing works well when it is grounded in real examples you provide.

How much does the AI cover letter generator cost?

One generation costs one dollar (USD) via secure checkout, unless you have Candidate Pro — Pro includes unlimited cover letter generations.

Can I download my cover letter as a PDF?

Yes. After generation you can download an English PDF formatted for job applications.

Should I use AI for my cover letter?

AI is strongest as a drafting partner: you supply accurate facts and the job posting, review the output, and personalize before sending. Never invent employers, titles, or metrics — hiring teams verify claims.

Do I need a cover letter if the job says optional?

Many US employers still read optional cover letters when deciding who to interview. A tailored letter helps you stand out when dozens of applicants share similar resumes — especially for competitive roles.

What is the difference between a cover letter and a resume?

Your resume lists experience and skills in a scannable format. Your cover letter tells the story behind your best wins and why you want this employer. Together they answer “Can you do the job?” and “Do you actually want it?”
