German-Speaking JSON & Coding Experts for Audio Evaluations

Temporary

Lifted, an Upwork Company™

Company Description

An Enterprise client is seeking a high volume of German-speaking coding experts with JSON expertise to combine language fluency, customer service judgment, and technical evaluation skills to help improve the quality, accuracy, and usability of AI-generated outputs, in an audio format.


Work is expected to begin right away, and continue for 2-3 months, with the potential for additional work beyond this initial project.


Experts may work at any schedule of their choosing, for as long as tasks are available. Experts (Operators) will review a mix of customer service-style responses and technical content, with a strong focus on coding knowledge, JSON structure, formatting accuracy, and overall response quality. Experts should be comfortable identifying whether outputs are clear, helpful, natural, technically accurate, and aligned with project guidelines.


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

Job Description

Tasks include:

  • 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 - the client is evaluating natural voice cadence.

Qualifications

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.


“Operator” requirements:
- Strong spoken-language proficiency: C1/C2-level fluency (CEFR) in the target evaluation language, verified through a speaking/listening assessment, not just a resume claim.
- 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


Ideal experts will have strong attention to detail, strong written communication skills, and the ability to evaluate both the customer experience and the technical correctness of a response. A solid understanding of JSON is especially important, including the ability to read, validate, troubleshoot, and identify structural or formatting issues.
