Outside IR35 Technical Author Contract Jobs

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.

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.

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 outside IR35, the engagement is treated as a business-to-business arrangement. The contractor operates through their own limited company, invoices for services, and manages their own tax affairs including corporation tax, self-assessment, and VAT where applicable.

Outside IR35 engagements are assessed against three key factors: the degree of control the client exercises over how the work is delivered, whether the contractor has a genuine right to provide a substitute, and whether there is a mutuality of obligation between the parties. Contracts that demonstrate contractor autonomy, project-based delivery, and the absence of ongoing employment obligations are more likely to sit outside IR35. Since April 2021, responsibility for making this determination sits with the end client for medium and large private sector organisations.

On QualityContracts.co.uk, approximately 28% of roles with a stated IR35 status are classified as outside IR35. The proportion varies by sector and role type, with some disciplines seeing a significantly higher or lower share of outside IR35 opportunities. Each listing on this page displays its IR35 status where provided by the hiring organisation.

Technical authoring is well suited to outside IR35. Producing a user manual, creating installation guides, or developing a documentation suite for a product release creates tangible deliverables. Defence, engineering, and technology companies commissioning specific documentation projects hire technical authors on this basis. S1000D, DITA, or other structured authoring standards are commonly required in defence and aerospace.

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. Rates shown are for outside IR35 engagements and reflect the gross day rate paid to the contractor's limited company before any personal tax obligations.

Over the past twelve months, we have tracked over 80 technical author contract roles across the site. Of the roles currently listed on our site, around one in four are Outside IR35. Data reviewed up to March 2026.
