# Industrial Engineers

US SOC code 17-2112. Markdown version of https://futurehistory.earth/timeline/17-2112

Also called: Process engineer, Lean engineer, Six Sigma engineer, IE, Operations engineer.

## In brief

In May 2025, [BLS](https://www.bls.gov/oes/special-requests/oesm25nat.zip) counted **365,740** US industrial engineers, with median pay of **$102,440** a year. Of the BLS counts since 2003, the May 2025 count is the highest. The earliest figure here is [an estimate](https://ethw.org/Frederick_Winslow_Taylor) of **15,000** from 1920, not measured the same way as today's count. The last full technology era for industrial engineers: ERP + simulation software, 2005 to 2020.

## What the sources say

### Official outlook

BLS projects employment to grow 12.4% from 2025 to 2035. Source: [BLS Employment Projections 2025-35](https://data.bls.gov/projections/nationalMatrix?queryParams=17-2112&ioType=o).

### AI exposure studies

- **60.5%** of this job's tasks are exposed to large language models. Not a forecast of job losses. [Eloundou and others, 2023](https://github.com/openai/GPTs-are-GPTs/blob/main/data/occ_level.csv)

Data as of BLS OEWS May 2025; BLS Employment Projections 2025-35. BLS publishes these counts as yearly survey snapshots and cautions against reading them as a precise trend. In May 2021 BLS changed how it estimates these counts (a model-based method using three years of survey data) and moved fully to the 2018 occupation codes, so part of a change across 2021 can come from the method rather than the work.
