Job description

About the role

We're hiring proficient bilingual speakers (English & Finnish) to help make advanced AI models safer. You'll apply your language fluency and cultural judgment to evaluate and strengthen how these models handle sensitive topics in Finnish. No prior AI/ML experience is required — we'll train you on the workflow.

What you'll do

• Write expert-level prompts in Finnish across a range of sensitive subject areas.




• Apply structured guidelines to classify prompts and conversations.




• Flag adversarial phrasings and escalation patterns, and document the reasoning behind your judgments.

What we're looking for

• Native or near-native fluency in Finnish, plus business-level written English.




• A bachelor's degree, completed or in progress.




• Strong written reasoning and a high level of attention to detail.



• Sound judgment around sensitive and dual-use information.

Nice to have

• Based in Finland or the wider Western Europe region. This is a preference, not a requirement — applicants based elsewhere are welcome.


• Experience reviewing, grading, or red-teaming written or technical content.


• Background in trust and safety, content moderation, policy evaluation, or adversarial testing.
