About Our Outside IR35 Generative AI Contract Roles
What does a generative ai contractor do?
As a contract Generative AI, you are hired to build, integrate, and deploy AI systems that create new content, including text, images, code, audio, and video, using large language models, diffusion models, and other generative architectures. The scope of generative AI contracting spans a wide range of practical applications: building enterprise chatbots and conversational AI assistants, implementing retrieval-augmented generation systems that allow language models to draw on proprietary data, fine-tuning foundation models on domain-specific datasets, integrating generative AI capabilities into existing products and workflows via API, and building the evaluation frameworks needed to measure and improve the quality of generative AI outputs in production.
Generative AI contractors are expected to have strong Python engineering skills as a foundation, alongside hands-on experience with the major foundation model providers and their APIs, including OpenAI, Anthropic, Google, and the open-source model ecosystem via Hugging Face. Experience building RAG architectures using vector databases such as Pinecone, Chroma, or pgvector, alongside retrieval and reranking approaches, is standard across the market for enterprise AI assistant and knowledge management use cases. Familiarity with LLM orchestration frameworks such as LangChain or LlamaIndex is broadly assumed for contractors working in this space. The ability to design robust evaluation pipelines, manage prompt engineering at scale, and handle the production engineering challenges specific to LLM-based systems, including latency, cost, hallucination, and safety, is a consistent differentiator at senior level.
What is the market like for generative ai contractors?
Generative AI is currently one of the fastest-growing and highest-value specialist areas within the broader technology contracting market. Demand has grown at an exceptional rate since the widespread emergence of accessible foundation models in 2023, and shows no sign of stabilising as organisations across every sector race to integrate generative AI capabilities into their products and operations. The supply of contractors with genuine production experience building and deploying generative AI systems, as opposed to prototype and proof-of-concept experience, remains very limited relative to demand. This structural imbalance is maintaining day rates at the very top of the technology contracting market for experienced generative AI specialists.
What does Outside 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 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.
What generative ai roles are usually Outside IR35?
Generative AI contracts have a reasonable outside IR35 rate, with around 35% sitting outside among those declaring IR35 status. The field is new enough that many engagements are structured as proof-of-concept builds, model evaluation projects, or strategy assessments with clear endpoints. Organisations exploring LLM integration, RAG architectures, or AI-powered product features frequently engage contractors for a defined exploration phase. The pace of change in generative AI means clients value contractors who can deliver quickly on a specific use case and move on.
How much do generative ai contractors usually earn when working Outside IR35?
Contract rates for generative ai roles typically range from £600 to £1050 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.
