About Our Inside IR35 Technical Author Contract Roles
What does a technical author contractor do?
Organisations bring in Technical Author contractors to produce clear, accurate, and structured documentation for software, engineering, and regulated environments. The work covers user guides, API documentation, system specifications, standard operating procedures, training materials, and regulatory submissions. Technical Author contractors are used across defence, aerospace, pharmaceuticals, financial services, and technology, wherever complex products or processes require documentation that meets professional or regulatory standards.
Strong writing ability is the foundation, combined with the capacity to absorb complex technical subject matter quickly and translate it for the target audience. Experience with structured authoring tools such as MadCap Flare, Adobe FrameMaker, Oxygen XML, or DITA-based content management systems is widely expected. For software documentation roles, familiarity with developer tools, Markdown, Git, and docs-as-code workflows is increasingly required. For regulated industries, knowledge of relevant documentation standards such as S1000D for defence or GxP for pharmaceuticals is a significant differentiator.
What is the market like for technical author contractors?
Technical Author contracting is a specialist but mature and active market. Defence and aerospace remain the largest single source of demand, driven by the documentation requirements of major programmes and the need to maintain technical publications to S1000D and similar standards. Software documentation is a growing segment as technology companies invest in developer experience and product documentation. Pharmaceutical and medical device companies provide steady demand for contractors experienced in regulated documentation. The market is relatively small but well paid for experienced specialists, and the move towards docs-as-code approaches in technology is creating new opportunities for technically minded authors.
What does Inside IR35 mean?
IR35 is UK tax legislation that determines whether a contractor is genuinely self-employed or working in a manner that resembles employment. When a contract is classified as inside IR35, income tax and National Insurance are deducted at source, typically via an umbrella company or agency PAYE. Headline day rates on inside IR35 engagements are generally higher than equivalent outside IR35 roles to account for the tax and employment cost structure.
Inside IR35 determinations are made where the working arrangements are considered to resemble employment, based on factors including the level of client control, the absence of a genuine right of substitution, and the presence of mutuality of obligation. Since April 2021, the end client is responsible for making this determination for medium and large private sector organisations. Many employers in financial services, government, and professional services assess the majority of their contractor engagements as inside IR35.
On QualityContracts.co.uk, approximately 49% of roles with a stated IR35 status are classified as inside IR35, making it the most common arrangement across the contract market. The proportion varies by sector and role type. Each listing on this page displays its IR35 status where provided by the hiring organisation.
What technical author roles are usually Inside IR35?
Inside IR35 technical authoring work is found in organisations with ongoing documentation programmes. The author joins the documentation or product team, maintains and updates existing manuals, and produces new content as products evolve. Defence contractors, engineering companies, and technology firms with regulated documentation requirements embed technical authors in their teams for sustained inside IR35 engagements.
How much do technical author contractors usually earn when working Inside IR35?
Contract rates for technical author roles typically range from £350 to £600 per day, depending on the scope of the role, required expertise, and the delivery expectations of the engagement. Inside IR35 rates are typically 15% to 30% higher than equivalent outside IR35 roles to account for tax and national insurance deducted at source by the fee-payer.
