How to Write a Cover Letter That Actually Gets Read in Tech

Do Tech Companies Actually Read Cover Letters?

The honest answer is: sometimes. At large tech companies with high application volume, cover letters are often skipped entirely in the first round. But at startups, for senior roles, and for any position where the hiring manager is directly involved in screening, a strong cover letter can meaningfully differentiate you from candidates with similar experience.

More importantly, writing a tailored cover letter forces you to articulate why you are the right person for this specific role — and that clarity often improves how you present yourself in interviews as well.

The Structure That Works

A cover letter for a tech role should be short (3–4 paragraphs, under 400 words), specific, and forward-looking. Here is the structure that consistently performs well:

Paragraph 1 — The hook (2–3 sentences) State the role you are applying for and lead with the most relevant thing about you. Do not open with "I am writing to express my interest in..." — that wastes the reader's attention. Instead, lead with a specific accomplishment or a direct statement of fit.

Example: "I built and shipped the payments infrastructure that processed $2B in transactions at [Company] — and I am excited to bring that experience to the Staff Engineer role at [Target Company], where scaling financial systems is at the core of the product."

Paragraph 2 — The evidence (3–4 sentences) Pick one or two specific accomplishments that directly map to the job description's key requirements. Use numbers wherever possible. This is not a summary of your resume — it is a curated argument for why you are the right hire.

Paragraph 3 — The company connection (2–3 sentences) Show that you have done your research. Reference something specific about the company — a product decision, a recent launch, a stated value — and explain why it resonates with you. Generic "I admire your culture of innovation" language is immediately recognizable and counterproductive.

Paragraph 4 — The close (1–2 sentences) A simple, confident close. Avoid begging or over-qualifying. "I would welcome the opportunity to discuss how my experience maps to this role" is clean and professional.

Common Cover Letter Mistakes in Tech

Summarizing your resume. The cover letter should add information, not repeat what is already on the resume. If a hiring manager reads both and learns nothing new from the cover letter, it was a wasted opportunity.

Writing one letter for all applications. A generic cover letter is almost always worse than no cover letter. If you do not have time to tailor it, skip it.

Focusing on what you want rather than what you offer. Phrases like "This role would help me grow my skills in..." center the narrative on your needs rather than the company's. Flip the framing: "My experience in X positions me to contribute immediately to Y."

Being too long. Hiring managers at tech companies are busy. A cover letter that exceeds one page will often not be read in full. Aim for 250–350 words.

A Template to Adapt

Dear [Hiring Manager's Name or "Hiring Team"],

[Hook — specific accomplishment + direct statement of fit for this role.]

At [Previous Company], I [specific achievement with numbers]. I also [second relevant achievement]. Both experiences map directly to [key requirement from the job description].

I have been following [Target Company]'s work on [specific product or initiative] and was particularly struck by [specific detail]. [One sentence on why this resonates with your professional goals or values.]

I would welcome the opportunity to discuss how my background aligns with what you are building. Thank you for your time.
