Remote AI Agentic Systems Engineer

YO AI Labs; Buenos Aires; A distancia; ARS 185.357.000 - 278.035.000; Jornada completa

Descripción de la vacante

Tether is seeking an AI Research Engineer (Agentic Post-training) to advance post-training for agentic models and tool use, with a focus on multi-modal data and edge deployment. You will collaborate across research, engineering, and product teams to push toward state-of-the-art capabilities.

The role emphasizes hands-on experimentation, scalable data pipelines, and rigorous evaluation, with remote worldwide collaboration and opportunities to publish and contribute to open-source projects.

Formación

• Degree in Computer Science, Machine Learning, or a related field; MS/PhD preferred.
• Experience with multimodal post-training workflows and data pipelines.
• Hands-on experience with distributed training frameworks (multi-node GPU environments).
• Demonstrated open-source contributions related to agentic systems or tool use (GitHub/HuggingFace).
• Publications at leading AI conferences (e.g., NeurIPS, ICML, ICLR).

Responsabilidades

• Conduct end-to-end research and engineering initiatives to advance post-training of agentic and tool-use models to achieve SOTA results.
• Drive cross-cutting model improvements, including factuality, instruction adherence, tool/function use, multi-agent coordination, and reasoning calibration.
• Design and enhance large-scale post-training systems, including data pipelines, training workflows, evaluation frameworks, and benchmark infrastructure.
• Develop rigorous evaluation suites and diagnostic tools to assess model readiness for deployment.
• Strengthen feedback loops from real-world product usage, incorporating explicit and implicit user signals into post-training.
• Collaborate with tooling, product, and training teams to improve usefulness, reliability, and agentic capabilities of frontier models.
• Liaise with research, engineering and cross-functional teams to determine production readiness for major model releases.
