Sr Python Developer - Remote

YO AI Labs was created around a clear need for dependable human expertise in the development of advanced AI systems. As generative models became more capable, companies still needed experienced professionals to evaluate generated content, identify errors, apply expert rubrics and provide reliable feedback. YO AI Labs developed a model that treats domain knowledge as the primary qualification: lawyers review legal reasoning, engineers assess generated code, designers judge visual output, and language specialists evaluate multilingual and localization work.

The company describes itself as an AI data solutions provider specializing in data annotation, data labeling, LLM training and evaluation, RLHF, and human-in-the-loop services. It also operates a remote job board that aggregates openings from platforms including Micro1, SuperAnnotate, Ethos AI, AfterQuery, and Handshake AI, while acting as a referral partner rather than the employer for those roles. Candidates can submit a CV for matching and access internal or external client hiring opportunities. Behind these services, YO AI Labs also hires for delivery, quality, talent sourcing, engineering and data, and business-development functions needed to operate its AI data business.
