Will AI replace chemical engineers? The data

Chemical engineers apply the principles of chemistry, physics and engineering to design equipment and processes for manufacturing products such as gasoline, detergents and paper. The US Bureau of Labor Statistics lists their duties as researching new and improved manufacturing processes, designing and planning equipment layout, setting safety procedures for working with dangerous chemicals, running tests and monitoring production, troubleshooting manufacturing problems, checking equipment and processes for safety and environmental compliance, and estimating production costs. About 28 percent work in chemical manufacturing.

The short answer: AI is more likely to change how chemical engineers work than to replace them. The ILO's 2025 index rates chemical engineers as minimal exposure, with a score of 0.35. The BLS projects employment to grow 5 percent from 2025 to 2035, faster than average, from 21,900 to 22,900 jobs, with about 1,100 openings a year. Projections are estimates, not guarantees.

How exposed chemical engineers are

The International Labour Organization scores occupations' tasks from 0 (cannot be automated with generative AI) to 1 (could be done without a human operator), and groups them into gradients from 1 to 4, with 4 the most exposed; below them sit minimal exposure and not exposed (ILO Working Paper 140, 2025).

Literature searches, calculations and reports can be sped up by generative AI. Designing a process, testing it and answering for its safety keep the job out of the exposed gradients.

What the BLS projects

The BLS says demand for chemical engineers depends largely on demand for the products they help develop. It gives the example of environmental and sustainability concerns leading chemistry and manufacturing firms to research alternative fertilizers, and expects chemical engineers to keep being needed to design equipment and processes that conform to changing regulations.

Where AI is helping

• Searching research literature and patents for prior work.
• Process simulation and modeling, and analyzing production data for problems.
• Drafting test plans, reports and cost estimates.

What stays with chemical engineers

• Safety: setting procedures for dangerous chemicals, where errors can hurt people.
• Compliance: making processes meet environmental and safety rules that keep changing.
• Testing: proving in the lab and the plant that a process works as modeled.
• Troubleshooting: finding out why a real production line is not behaving.
• Checking AI help: generated calculations, data and citations can be wrong, which NIST calls confabulation (NIST AI 600-1). See checking AI output.

How the job is changing

AI makes research, modeling and paperwork faster, and the engineer stays responsible for safe, compliant processes. The BLS says chemical engineers need a bachelor's degree in chemical engineering or a related field; a Professional Engineer license is not needed to start but is open to experienced engineers.

Pay and how to get in

The US Bureau of Labor Statistics puts the median annual pay for chemical engineers at $125,040 in May 2025, against $50,980 for all workers. The typical education needed to enter is: bachelor's degree. See how this job compares in AI exposure by pay and AI exposure by education level.
