Job Responsibilities
Welo Data is seeking a creative and analytical Prompt Engineer & Data Analyst

to join our team.

In this role, you will be instrumental in refining and evaluating large language models (LLMs).

You'll design prompts, create high-quality datasets, and perform rigorous analysis to directly

improve the functionality, accuracy, and safety of cutting-edge AI systems. Your expertise will

help us build smarter, more reliable, and more helpful technology.

Key Responsibilities
Prompt Engineering & Model Evaluation

  • Design, test, and iteratively refine complex and creative prompts to enhance AI model
  • capabilities in reasoning, instruction following, and contextual understanding.
  • Conduct rigorous side-by-side (SxS) comparisons of AI-generated outputs, providing
  • detailed rationales and quality ratings to identify the superior response.
  • Develop "golden" datasets, ideal responses, and granular evaluation rubrics to
  • serve as benchmarks for model training and performance analysis.
  • Engineer adversarial prompts and red-team scenarios to systematically identify
  • model vulnerabilities, biases, and safety gaps across various policies (e.g., Harassment,
  • Hate Speech, Dangerous Content).

Data Curation & Analysis

  • Create, annotate, and review diverse datasets across text, audio, and video formats to
  • support model training and localization.
  • Perform in-depth fact-checking and analysis to ensure model responses are accurate,
  • relevant, and grounded in reliable sources.
  • Establish and document style guides, content standards, and evaluation procedures
  • to ensure consistency and quality across all projects.
  • Analyze model outputs to identify trends, document error patterns, and categorize
  • failures, providing actionable feedback to engineering teams.

Collaboration & Training

  • Train, mentor, and guide other team members on prompt engineering best practices,
  • evaluation methodologies, and quality standards.
  • Collaborate with engineering and product teams to translate evaluation insights into
  • actionable model improvements.

Multimodal AI Training

  • For voice projects, script and perform dialogues portraying various personas (e.g.,
  • customer, agent) and accents to generate realistic conversational data for AI voice
  • agents.
  • For video projects, author precise text prompts using professional video production
  • terminology (e.g., shot angles, camera movements, lighting) to guide generative video
  • models.

Qualifications
Additional Job Details:

  • Bachelor's degree or equivalent experience in Linguistics, Computational Linguistics,
  • Communications, Technical Writing, or a related analytical field.
  • Native or near-native fluency in English with exceptional writing and editorial skills.
  • Proven experience in a role involving AI data annotation, content quality review, search
  • quality rating, or prompt engineering.
  • A highly detail-oriented and analytical mindset, with the ability to deconstruct complex
  • instructions and evaluate outputs with precision.
  • Ability to interpret code, datasets, and system workflows at a conceptual level (no
  • coding required).
  • Ability to work independently and manage workflows effectively in a remote environment.

Nice to Have

  • Multilingual proficiency in one or more languages in addition to English.
  • Direct experience with generative AI tools for text, voice, or video.
  • Background in QA testing, rubric design, or AI safety and ethics evaluation.
  • Familiarity with data annotation platforms and model evaluation tools.
