Project Sceptrum - Multilingual AI Coding Evaluation Specialist - Japanese

Join a short, paid project that tests whether AI coding agents work as well on instructions written in the target language as they do in English. Your language skills and technical background decide where you fit.

About the project

Welo Data is helping evaluate how well AI coding agents perform when the instructions they receive are written in languages other than English. Agents are given a real software engineering task in a code repository, and automated tests check whether they solved it. The code, repositories and tests stay exactly as they are. Only the human-written instructions change language, so the quality of every instruction directly affects the result.

About the roles

There are two roles on this project. We place you in one of them based on your experience & skillsets.

• Translator: translate English software engineering task briefs into the target language. You keep every requirement, constraint and success condition, and you leave commands, file paths, API names, code and test conditions exactly as written in English. This role suits people with a stronger technical background, and translation experience is a plus.

• Reviewer: compare each translation with the English source, check that nothing is missing, added or changed in meaning, correct errors, and log each correction by error type. This role suits people with strong translation, editing or review experience and enough technical familiarity to read code context.

Who we are looking for

• Native or near-native writing in the target language, and strong reading ability in English.

• Either professional experience in translation, editing, review or technical writing, or a software background combined with excellent writing in the target language

• Comfort reading technical text. Coding experience is a strong plus for the translation role and helpful for the review role.

• Close attention to detail. In this project, a dropped clause can make a task fail.

Project at a glance

• Project duration: one week since the mid of November

• Languages: Japanese

• Project time commitment: 6 hours per person

• Project compensation: varies depends on different programming language

• Work location: fully remote

How selection works (major steps)

1. Screening questions: about 2 minutes. They cover your language background, translation and review experience, which programming languages you know and how well, and your availability.

2. Language test: short exercises in the target language.

3. Programming skills assessment: you will be invited to another opportunity, in the programming language you know best (Rust, Go, Python, or TypeScript / JavaScript). It confirms your technical level and places you in a language track.

4. Financial Onboarding & Role placement: complete the financial onboarding with Welo Data. In the meanwhile, you will be informed about the decision whether you are placed in the initial translation role or the review role.

5. Production: once you finish all steps above, our project team will contact you for production.
