Project Perseus | Data Labeling Analyst - Dutch Speakers (Speech & Voice AI)

Weloglobal · California / Sunnyvale, CA / San Francisco, CA / Seattle, WA / Redmond, Washington / Burlingame, CA / New York City Metropolitan Area

Overview

Welo Data is looking for detail-oriented and reliable individuals to join our team as Data Labeling Analysts, supporting speech and voice AI systems.

This is a high-impact production role focused on building the datasets that power real-world AI systems. You’ll be working with audio, speech, and language data — helping ensure models are trained on accurate, well-structured, and representative inputs.

While this role is more execution-focused than evaluation-heavy roles, it still requires strong judgment, attention to detail, and consistency. The work sits at the intersection of language, data, and AI systems — where precision and discipline matter at scale.

We’re looking for people who are dependable, focused, and take pride in producing high-quality work, even across repetitive workflows.
