If you’re passionate about making a mark in the fintech space, this is your opportunity to collaborate with some of the brightest minds, pushing boundaries and setting new standards. We’ve grown fast, stayed lean, and secured our place as a leader in the industry.\nIf you have excellent English communication skills and are ready to contribute to the most innovative platform on the planet, Tether is the place for you.\nAre you ready to be part of the future?\nAbout the job\nAs a member of the AI model team, you will drive innovation in post-training methodologies, with a special focus on agentic behaviors and tool use. Your work will refine pre-trained models so that they not only deliver enhanced intelligence and domain specific capabilities, but also learn to reason, plan, and autonomously invoke external tools to solve real world, multi step tasks and applications on edge devices (i.e., smartphones).\nYou will work on a wide spectrum of systems, ranging from streamlined, resource efficient agents that run on limited hardware to complex multi modal architectures integrating text, images, and audio, all optimized for tool augmented decision making.\nWe expect you to have deep expertise in large language model architectures and substantial experience in post-training for agentic workflows, including tool use fine tuning, function calling, and reinforcement learning from feedback on multi turn interactions. You will adopt a hands-on, research driven approach to developing, testing, and implementing new post-training algorithms that unlock goal directed behavior, self correction, and reliable tool invocation.\nYour responsibilities include curating agentic training data (e.g., trajectories of tool use, reasoning chains, environment interactions), strengthening baseline performance, and identifying as well as resolving bottlenecks in post-training for tool augmented agents to achieve SOTA model quality. The goal is to build models that do not just know but also act, use tools, and adapt, pushing the limits of what agentic AI can achieve.\nResponsibilities\nConduct end-to-end research and engineering initiatives to advance post-training of agentic and tool-use models to achieve SOTA results.\n\nDrive broad, cross-cutting model improvements, including factuality, instruction adherence, tool/function use, multi-agent coordination, and reasoning calibration.\n\nDesign and enhance large-scale post-training systems, including data pipelines, training workflows, evaluation frameworks, and benchmark infrastructure.\n\nDevelop rigorous evaluation suites and diagnostic tools to assess model readiness for deployment.\n\nStrengthen feedback loops from real-world product usage, incorporating both explicit and implicit user signals into post-training.\n\nCollaborate with tooling, product, and training teams to improve the usefulness, reliability, and agentic capabilities of frontier models.\n\nClosely liaise with research, engineering and cross-functional teams to determine which integrations are production-ready for inclusion in major model releases.\n\nRequirements\nDegree in Computer Science, Machine Learning, or a related field; advanced degree (MS/PhD) preferred with a strong publication record in top-tier AI conferences.\n\nExperience with multimodal post-training workflows and data pipelines, particularly for agentic systems and tool use.\n\nHands-on experience applying post-training at scale using distributed training frameworks (e.g., multi-node GPU environments).\n\nDemonstrated experience improving model capabilities in areas such as reasoning, tool use, and multi-agent coordination that achieve SOTA results.\n\nProven track record of open-source contributions related to agentic systems or tool use (code, datasets, or models) on platforms such as GitHub or Hugging Face.\n\nPublications at leading AI conferences (e.g., NeurIPS, ICML, ICLR, ACL, CVPR, ECCV).\n\nImportant information for candidates\nRecruitment scams have become increasingly common.
