The Bridge Between Human Judgment and AI Excellence

Are you an experienced QA professional who knows how to mentor others and maintain a high bar for data integrity? Welo Data is seeking Data Quality Analysts for Project Perseus .

This isn't just about labeling; you are the Quality Gatekeeper . You will bridge the gap between our Data Labeling Associates (DLAs) and Team Leads, ensuring that human feedback for cutting-edge Portuguese (Portugal) AI models is not only accurate but world-class.

The Mission: Leading the Quality Loop

  • Human-to-Human Auditing: Audit the work of DLAs, providing structured, actionable feedback to drive team-wide improvement.
  • Tactical Support: Act as the first line of defense for the team—answering complex linguistic questions and interpreting evolving guidelines.
  • Onboarding & Coaching: Lead hands-on training for new associates, helping them navigate the nuances of Portuguese (Portugal) dialects and AI safety.
  • Workflow Orchestration: Monitor queues and identify blockers, escalating risks to Team Leads before they impact the program.
  • Strategic Insights: Spot high-level patterns in both human and model behavior, contributing directly to the evolution of project guidelines.

Project Details

  • Employment Type: W2 Full-Time Employee
  • Hours: 40 hours/week
  • Location: California (On-Site: San Francisco, Sunnyvale, or Burlingame)
  • Pay Rate: 38 $ (per hour)

What We’re Looking For

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

Premium Campus Benefits

  • Gourmet Dining: Free breakfast, lunch, and dinner with a wide variety of cuisines.
  • Office Perks: Micro-kitchens stocked with premium coffee, La Croix, and healthy snacks.
  • Wellness & Security: Comprehensive Medical, Dental, and Vision + 401(k) and HSA eligibility.
  • Modern Campus: Access to rooftop nature parks and state-of-the-art collaborative workspaces.
  • Commuter Benefits: Free shuttles, transport perks, and bike-to-work support.
