What the Data Shows
- AI engineer ranked as the number one fastest-growing job title in the United States in LinkedIn's Jobs on the Rise research, with postings up 143 percent year on year in 2025.
- Four of the top five fastest-growing roles are AI-related.
- One analysis found AI and machine-learning job postings rose 163 percent from 2024 to 2025, reaching about 49,200 positions in the US.
The Four Fastest-Growing AI Roles
AI engineers — also called machine learning engineers — design and build AI systems for prediction and problem-solving.
AI consultants and strategists help organisations plan and deploy AI to improve how they work.
AI and machine learning researchers design, test and refine models to advance what they can do.
Data annotators label and review the data used to train AI — often an accessible entry point into the field.
The Skills Growing Fastest
LinkedIn identifies AI engineering, prompting and model tuning as the fastest-growing skills of 2026. For AI engineering roles, frequently requested technical skills include PyTorch, LangChain and retrieval-augmented generation (RAG).
The Global Picture
The World Economic Forum's Future of Jobs Report 2025 named big data specialists, fintech engineers and AI and machine learning specialists as the three fastest-growing job categories worldwide for 2025 to 2030.
How to Start Building These Skills
- Get fluent with AI tools at your current job. Using AI well is valued far beyond technical roles — start with how to write effective prompts.
- Learn the core concepts. Understand what AI agents are and how AI pricing and tokens work.
- Build small, real projects and share them — a working project often speaks louder than a certificate.
- Pair AI with your existing expertise. An accountant, nurse or marketer who understands AI brings context a pure technologist may lack.
- Learn to check AI output. Employers value people who can spot errors — see why AI makes things up.
Keep Perspective
Fast growth in postings starts from a smaller base than long-established professions, and competition for top roles is strong. But the direction is clear: AI skills are becoming valuable across nearly every industry, not only in technology companies.
