Mr. Caleb Sorensen Documentation Manager Stanchion Software Durham, United States
Application for Senior Technical Writer, Developer Documentation, Stanchion Software
Dear Mr. Sorensen,
I am applying for the Senior Technical Writer, Developer Documentation post at Stanchion Software. I currently own an API reference of about 480 endpoints and a 210-page developer guide on a quarterly release train, written for integration engineers implementing against a deadline.
The work I would most want to bring over is how those docs ship. When I took the set on, documentation followed a release by an average of 11 days, because it lived in a separate tool and a separate process. I moved it into the product repository as Markdown, reviewed by pull request with link checking and a build test in the pipeline, and made reference pages part of the definition of done. Release-to-docs lag is now same day. Separately, I read two quarters of support tickets, rewrote the twelve most-visited how-to topics as task-based procedures, and tickets tagged to those pages fell 38% over the following two quarters.
I spent an hour in your public documentation this week. The reference is strong and the quickstart is clear, but the quickstart assumes an already-authenticated client, and the token exchange it depends on is documented three pages away under a different name. That gap is where a new integrator stalls, and it is the first thing I would fix. I would also want to look at whether your search is returning the migration guide for version queries, since that is a common place for a two-version docs set to leak tickets.
Published pages I wrote between 2019 and 2022 are listed on my resume, and I can walk through the repository workflow in detail. I can start within four weeks. Thank you for your time.
Sincerely, Quillan Duplantier
Summary
A technical writer cover letter names the documentation set you own, the toolchain you ship it in, and one accurate observation about the employer's own documentation. This guide gives you a full adaptable letter, what to say when your work is behind a login, and the openings that get a strong application set aside.
Technical Writer cover letter examples by experience level
In short, a technical writer cover letter is a one page letter that names the documentation set you own, the toolchain you ship it in, and one thing you noticed in the employer's own documentation.
Readers judge it twice. First, once for what it says, and then once as a specimen of your writing. As a result, a documentation manager reading a letter full of unsupported adjectives has learned something about how you would write a procedure, and it is not good news.
Guide to a technical writer cover letter
To help, this guide and the corresponding technical writer cover letter example will cover:
- First, how to structure the letter, paragraph by paragraph
- Next, why one accurate observation about their docs beats a paragraph of praise
- What to write when everything you have produced is behind a login
- Also, how to talk about tooling honestly without sounding underqualified
- Finally, the openings that make a reader set a strong application aside
How to write a technical writer cover letter
| Paragraph | Its job | Length |
|---|---|---|
| Opening | The role, the kind of documentation you own, its size | 2 to 3 sentences |
| Evidence | One change you made, and how you know it worked | 4 to 5 sentences |
| Fit | One accurate observation about their documentation, and what you would do first | 3 to 4 sentences |
| Close | Sample link, availability, thank you | 2 sentences |
Read their documentation before you write the letter
Almost no other occupation hands candidates the employer's actual work product before the interview. Public documentation is right there, and half an hour with it puts you ahead of nearly every other applicant.
Look for the things a working writer would notice. Does the quickstart assume you already have credentials? Is the first failure case documented anywhere? Is there one term used three ways across three pages? Does the reference agree with the guide? Are the code samples runnable against the current version?
Then write one sentence about it in the letter. Not a critique and not a list. One observation, stated without contempt, followed by what you would do about it.
That sentence does three jobs at once. It proves you read documentation for a living, it demonstrates your judgment about audiences, and it gives the interviewer something concrete to open with.

What to write when your work is behind a login
However, most technical writing is internal, proprietary or under a non-disclosure agreement. That is normal and no manager will hold it against you, as long as you say so rather than going quiet.
| Situation | What the letter says |
|---|---|
| Docs are behind a customer login | Names the set, size and audience, offers a redacted sample of one procedure |
| Everything is under a non-disclosure agreement | Describes the structure and toolchain, and offers to write a short timed sample |
| Docs were published but you have since left | Gives the site and the years you owned it, and says which sections were yours |
| You only have internal wiki work | Names the wiki's size, the audience, and the change in how often support escalated |
| You are moving in from support or engineering | Names the runbooks, release notes or knowledge base articles you already wrote in that role |
In addition, employers routinely request writing samples in this occupation, sometimes as a short timed exercise. Offering one before anyone asks reads as confidence rather than presumption.
Tooling honesty and the transferable claim
Name the exact toolchain you have shipped in, including how documentation gets reviewed. Say which parts you set up rather than inherited. When their stack differs from yours, name the closest thing you have done and say what you expect to learn. Give the size of your docs set in topics or pages, and the number of live versions. Offer a writing sample in the letter.
Do not list every tool you have opened, since the interview will test one of them. Do not claim structured authoring experience because you once opened an XML editor; DITA and a component content management system are a working practice, not a file format. Do not apologize for coming from support, engineering or teaching, because that is the normal route in. Do not send a letter that does not mention their product.
A small occupation with a high median, so the letter is doing real work
Technical writers had a median annual wage of $90,390 in May 2025, against $74,250 for media and communication occupations as a whole and $50,980 for all occupations (BLS Occupational Outlook Handbook, May 2025, published 27 August 2026).
It is also a small occupation: 46,400 jobs in 2025, projected to grow 1 percent through 2035, an increase of about 400 jobs, with roughly 3,200 openings a year (BLS, 2025 to 2035 projections).
Well paid and small means each posting draws a deep pile, including writers from support, quality assurance and engineering backgrounds who know the domain cold. A letter that only asserts writing ability is competing on the one dimension every applicant claims. A letter that names a docs set, a toolchain and a piece of evidence is competing on three that most of them cannot.
Length, format and sending it
One page, four paragraphs, 250 to 400 words. PDF unless the application says otherwise, named plainly: quillan-duplantier-senior-technical-writer-cover-letter.pdf.
Address a person. Documentation managers, developer experience leads and engineering managers are usually findable, and getting the reporting line right also tells you who your reader is: a docs manager wants the toolchain, an engineering manager wants to know you will not slow the release.
Use the same figures as your resume so the two agree. Our technical writer resume example is written with the numbers used here.
Key takeaways
- To start, name the docs set and its size in the first two sentences.
- Then say how it ships: repository, review mechanism, release cadence.
- Also, give one change you made and the evidence that it worked.
- Similarly, spend half an hour in their documentation and write one accurate observation.
- At the same time, be honest about tooling gaps and name the nearest thing you have done.
- Offer a writing sample, or a redacted one if your work is confidential.
- In short, one page, addressed to a named person, written the way you write a procedure.

Technical writer cover letter questions, answered
How long should a technical writer cover letter be?
One page, four paragraphs, 250 to 400 words. The letter is read as a sample of your writing, so length works against you twice: once as a claim on the reader's time and once as evidence that you do not edit.
Is a cover letter necessary for a technical writing job?
Yes, more than in most fields. It is the only unedited writing the employer is guaranteed to see before a screening call, and many teams treat it as the first sample. Some postings say a writing sample is required and the letter is what gets judged if you do not send one.
Should I critique their documentation in the letter?
One observation, framed as something you would work on, not as a fault list. Documentation gaps almost always have a history: a deadline, a departure, a reorganization. A candidate who states a gap neutrally and says what they would do sounds like a colleague. A candidate who audits the docs site in six bullet points sounds like a problem.
What if I have never used their toolchain?
Say what you have shipped in and what you expect to pick up. Naming the closest equivalent honestly is stronger than a vague claim. Most managers hire for the ability to learn a toolchain, and the underlying skills of versioning, review and structured content transfer between them.
How do I move into technical writing from another job?
Write the letter around the documentation you already produce. Support agents write knowledge base articles, engineers write runbooks and release notes, teachers write procedures for people under pressure. Name that work, give its size and audience, and offer one rewritten sample. BLS gives the typical entry route as a bachelor's degree plus fewer than five years in a related occupation (BLS Occupational Outlook Handbook, 2025), which describes exactly that move.
