[Hiring] Greek-Speaking JSON & Coding Experts for Audio Evaluations @Lifted, an Upwork Company™

Role Description

An Enterprise client is seeking Greek-speaking coding experts with JSON expertise to support the evaluation and improvement of AI-generated audio responses. Work is expected to begin right away and continue for 2-3 months, with the potential for additional work beyond this initial project.

• Participating in live, real-time conversational scenarios with AI systems
• Reviewing and labeling conversation transcripts
• Evaluating AI-generated responses using structured rubrics and providing written justifications
• Assessing responses for language quality, customer experience, technical accuracy, formatting, and JSON structure
• Capturing required session artifacts, including recordings, Session IDs, and tool-call/console logs
• Environment preparation and tool verification before each session
• Experts should speak naturally and spontaneously, as if responding in real time, without pre-planned, written, or scripted responses

Qualifications

• Strong spoken-language proficiency: C1/C2-level fluency (CEFR) in the target evaluation language, verified through a speaking/listening assessment
• Technical literacy: JSON fluency required - reading, validating, troubleshooting, and identifying structural/formatting issues
• Audio setup: capable of producing clear audio quality with no background noise

Requirements

• To be considered for this project, experts are required to pass a basic computational concepts assessment (JSON structures, function, general reasoning, and language proficiency), which takes about 15 minutes to complete, and will not be compensated
• If the expert passes the assessment, they will be provided with further onboarding steps

Company Description

Fluency in Greek is required. Experts with multilingual fluency may be offered work for this project and/or others, in additional languages.

• Ideal experts will have strong attention to detail
• Strong written communication skills
• The ability to evaluate both the customer experience and the technical correctness of a response
• A solid understanding of JSON is especially important
