# Executive Summary

## 01 A mirror of OpenAI: senior builders, not an academic dream team

The figures below reflect the Metix AI database scope (data as of roughly the first half of 2026), with the population = technical staff currently employed at Anthropic (engineering and research tracks, excluding non-technical roles such as community ambassadors, marketing, recruiting, and product). All numbers are aggregate statistics; the report shows no individual information.

- **1,281** current Anthropic technical staff
- **13.1 years** Median career experience
- **72%** over 10 years
- **15.5%** hold a PhD (Slightly above OpenAI's 14.4%)
- **13 months** Median current tenure
- **44%** on the job under a year
- **86%** based in the US

_Median career experience is 13.1 years, with 72% past the 10-year mark; only 15.5% hold a PhD, and the skills leaderboard is led by machine learning, Python, distributed systems, and Java._

## 02 Newer than OpenAI: four in ten joined in just the past year

About 44% have been on the job under a year, nearly three-quarters joined within two years, and only 4% have stayed four full years.

- **Under 12 months**: 568 · 44%
- **12 – 24 months**: 386 · 30%

## 08 How to use this X-Ray

### If you're competing with Anthropic for talent

Target the layer under 24 months of tenure; draw from big-tech infrastructure teams like Google, Meta, Microsoft, and Amazon, and don't overlook DeepMind and OpenAI.

### If you want to join a team like this

Bring the systems you genuinely built and carried through scale — the median bar here is 13 years of shipped engineering, not citation counts.
