Life Sciences Technical Writer Job Description

A Life Sciences Technical Writer's job is to figure out what someone needs to know, determine the clearest way to say it, and then make sure the document is accurate and stays accurate as the underlying technology changes. That sounds simple; it rarely is.

In scientific and technical organizations, the writing challenges are compounded by subject matter that requires genuine understanding to represent faithfully. A Technical Writer documenting a flow cytometry instrument needs to understand compensation matrices well enough to write a procedure that a new user can follow correctly. A Regulatory Affairs Writer assembling a 510(k) submission needs to understand the predicate device logic, the applicable performance standards, and how the FDA's reviewer will work through the technical file.

The job involves a lot of time with subject matter experts — engineers, scientists, clinical specialists, regulatory professionals — extracting accurate information from people who know their domain well but often lack time or inclination to write about it. Strong Technical Writers ask precise questions, build credibility with domain experts, and translate what they hear into documentation that is accurate under scrutiny.

In pharmaceutical and medical device companies, documentation is regulated. SOPs, batch records, and device history files live under change control: every revision requires a formal approval workflow, and superseded versions must be archived. Changes to validated software require impact assessments before the documentation is updated. The discipline of document control is as important as the writing itself in these environments.

In software and product companies, the pace is faster and the documentation footprint is broader — release notes, API references, embedded help text, community knowledge bases. Technical Writers who can work within development workflows, use Git, and update documentation in parallel with product releases are increasingly in demand.

Education:

• Bachelor's degree in English, technical communication, journalism, or a scientific/engineering discipline
• Graduate certificate in technical writing for career changers from science or engineering backgrounds
• Scientific or engineering degree plus demonstrated writing ability (portfolio) for regulatory and specialist roles

Certifications (useful, not universally required):

• Certified Professional Technical Communicator (CPTC) from the Society for Technical Communication
• Good Documentation Practices (GDP) training for pharmaceutical and medical device environments
• RAC (Regulatory Affairs Certification) for writers who want to advance into regulatory strategy roles
• Document control system training: Veeva Vault, MasterControl, Documentum

Technical tools:

• Authoring: MadCap Flare, Adobe RoboHelp, Oxygen XML, Microsoft Word with styles
• Content management: Confluence, SharePoint, Veeva Vault, Documentum
• Diagramming: Visio, Lucidchart, draw.io
• Version control: Git, SVN (for software documentation environments)
• Style guides: Microsoft Manual of Style, Chicago, house style guides

What hiring managers actually screen for:

• Writing samples that demonstrate accuracy in a technical domain
• Evidence of managing review cycles with multiple stakeholders
• Familiarity with document control concepts in regulated industries
• Ability to scope a documentation project and estimate effort realistically

The Bureau of Labor Statistics projects steady demand for Technical Writers, with growth outpacing some comparable professional roles. In scientific and regulated industries, the demand picture is particularly strong.

Pharmaceutical pipelines remain deep, and every drug or device moving through FDA review generates thousands of pages of required documentation. The number of submissions has grown without a proportional increase in the regulatory writing workforce, and experienced regulatory writers who understand eCTD structure, submission formatting, and agency expectations are in short supply. Entry-level regulatory writing roles are competitive, but mid-career writers with 3–5 FDA submissions in their portfolio have real negotiating leverage.

In software and technology, the demand for API documentation and developer experience writing has grown with the expansion of developer tools, platforms, and SDKs. Technical writers who can read code, understand APIs, and work in GitHub alongside engineering teams earn at the upper end of the general technical writing range.

AI is changing the job more than it is eliminating it. First-draft generation for boilerplate sections, translation of specifications into documentation prose, and structured content reuse are all being automated to some degree. What remains — verifying that the documentation is accurate, that the regulatory document meets current agency expectations, that the user procedure works the way it's described — requires domain knowledge and judgment that current AI tools cannot reliably provide.

For writers entering or advancing in the field, specialization accelerates career development. A Technical Writer who becomes the regulatory submission expert, the DITA/structured content specialist, or the API documentation authority at their organization earns more and has more career optionality than a generalist. The path from senior writer to documentation manager, content strategy lead, or regulatory affairs specialist is well-traveled.

Dear Hiring Manager,

I'm applying for the Life Sciences Technical Writer position at [Company]. I have five years of technical writing experience, the last three in pharmaceutical regulatory documentation at [Company], where I contributed to two NDA submissions and led the documentation package for a 505(b)(2) application that received approval last year.

My work at [Company] has been concentrated in Module 3 chemistry, manufacturing, and controls documentation — specifically drug substance and drug product process descriptions, specification development narratives, and container closure system descriptions. I work closely with CMC scientists and analytical development to make sure process descriptions match what actually happens in the manufacturing suite, not just what the batch record says should happen.

The part of this work I find most valuable is the review cycle discipline. A Module 3 section that goes to FDA review with internally inconsistent terminology or a process description that doesn't match the batch record creates avoidable delays. I've built a cross-reference checklist for each section type that our team now uses as a standard review step before any CMC document goes to final approval.

I'm drawn to [Company]'s pipeline because [specific reason — novel modality, therapeutic area, platform]. I'm interested in contributing to submissions at an earlier development stage, where documentation decisions made in Phase 2 have real impact on the Phase 3 filing. My experience with [specific module or section] would transfer directly.

Thank you for considering my application.
