Project Perseus | Data Labeling Analyst - Swedish Speakers (Speech & Voice AI)
Welo Global, Sunnyvale, CA, United States
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.
