About The Position

Welo Data is seeking Data Quality Analysts for Project Perseus. This role is for an experienced QA professional who can mentor others and maintain a high bar for data integrity. The analyst will bridge the gap between Data Labeling Associates (DLAs) and Team Leads, ensuring that human feedback for cutting-edge Arabic AI models is not only accurate but world-class. This position isn't just about labeling; it's about being the Quality Gatekeeper.

Requirements

2–4 years in data annotation, QA, content quality, or human-in-the-loop (HITL) workflows.
Professional-level proficiency in German and a University Degree (Bachelor’s or higher).
B2 level or superior English to handle stakeholder syncs and technical reporting.
Prior experience auditing or reviewing the work of others; you know how to coach without micromanaging.
A high bar for quality and the ability to stay consistent while guidelines shift in real-time.
Familiarity with safety, compliance, or policy-driven evaluation in a GenAI context.

Responsibilities

Audit the work of DLAs, providing structured, actionable feedback to drive team-wide improvement.
Act as the first line of defense for the team—answering complex linguistic questions and interpreting evolving guidelines.
Lead hands-on training for new associates, helping them navigate the nuances of Arabic dialects and AI safety.
Monitor queues and identify blockers, escalating risks to Team Leads before they impact the program.
Spot high-level patterns in both human and model behavior, contributing directly to the evolution of project guidelines.
