We analysed 5,000 AI-related job postings from March 2026 to identify which skills employers are paying the biggest premiums for. The results might surprise you.
1. Prompt Engineering
Median premium: +32% salary uplift. Prompt engineers who can reliably produce consistent, accurate outputs from LLMs are in extreme demand. This is not just writing questions — it's systems thinking applied to language models.
2. LangChain & LLM Orchestration
Building multi-step AI agent pipelines using LangChain, LlamaIndex, or similar frameworks commands some of the highest salaries in the field. We use these daily in our AI services.
3. Vector Databases & RAG
Retrieval-Augmented Generation (RAG) is the dominant pattern for enterprise AI applications. Pinecone, Weaviate, and pgvector skills are highly sought after.
4. Python for AI/ML
Still the foundation. Pandas, NumPy, Scikit-learn, and FastAPI for building AI microservices. Essential for any serious AI role.
5. n8n / Make Automation
Low-code automation builders are now enterprise-grade. n8n in particular has become the go-to for AI workflow automation, and specialists command £60–90k roles.
