Materials science intern

We seek detail-oriented human annotators to label technical documents about engineered metallic materials, including patents, standards, datasheets, and research literature.

Job Scope

1. Label entities such as material identities, composition specifications, material states, and sources.
2. Record composition constituents, amounts, and units exactly as written.
3. Capture stated links such as material-to-composition, material-to-state, claim/example relationships, and coreference.
4. Preserve span IDs and verbatim text needed for later resolution.
5. Leave external classification, normalization, equivalence mapping, unit defaulting, and material-family decisions to a separate expert resolution process.
6. Nice to have/stretch: help develop or evaluate LLM-assisted annotation workflows that improve productivity while preserving human review quality.

• The role requires accuracy, consistency, and restraint
• Requirements：

1. Strong reading comprehension for technical English and/or Chinese.
2. Familiarity with materials science, metallurgy, chemistry, patents, or technical documentation.
3. Ability to preserve exact spans, wording, units, ranges, and symbols.
4. Attention to document context, especially references such as "said alloy," "Example 2," or "the composition."
5. Comfort following structured annotation guidelines and recording labels consistently.
6. Good judgment about when information is explicitly stated versus inferred from outside knowledge.
