We aim to design intelligent systems that create exponential efficiency, enhance user experiences, and unlock new sources of revenue. Responsibilities AI Product Architecture & Development Architect, build, and deploy LLM‑powered applications that augment and automate key workflows across Yuno—from customer service and new product development to internal agentic workflows that optimize critical company processes. Design autonomous AI systems that can execute technical analysis, testing, troubleshooting, and decision‑making at scale. Develop AI‑driven tools that create measurable business impact—improving efficiency, accelerating innovation, and driving revenue growth. Operational Intelligence & Scalability Identify areas across Yuno where AI can generate efficiency gains—reducing manual work, optimizing processes, and enabling smarter operations. Build AI systems that enable Yuno to scale without exponential growth in headcount, thereby creating sustainable productivity and organizational intelligence. Data & Model Optimization Lead fine‑tuning and contextual optimization of AI models using Yuno’s proprietary data. Continuously refine performance through structured feedback loops, observability metrics, and user interaction data. Ensure adherence to privacy, compliance, and ethical AI principles in all model development. Cross‑Functional Collaboration & Innovation Work closely with data, product, and infrastructure teams to define the long‑term AI roadmap for Yuno. Experiment with emerging AI technologies to identify new capabilities that can drive differentiation and strategic advantage. Contribute to a culture of experimentation, rapid iteration, and continuous learning across the AI function. Skills & Experience 5+ years of professional experience in AI/ML development, with at least 2 years focused on LLMs, RAG, or agentic systems. Strong engineering and product mindset—capable of balancing technical depth with strategic impact. Exceptional communication and collaboration skills to work across product, engineering, and data functions. Passion for pushing the boundaries of applied AI and creating systems that drive real business transformation. Minimum Qualifications Experience designing and deploying systems using models like GPT, Claude, Gemini, or similar—including Retrieval‑Augmented Generation pipelines and contextual retrieval systems. Hands‑on experience with frameworks such as Crew.ai, LangChain, LangGraph, or similar for orchestrated agentic workflows. Expertise in supervised fine‑tuning (SFT), LoRA, or custom dataset adaptation for domain‑specific tasks. Proficiency in Python, Go, and AI/ML libraries such as PyTorch, TensorFlow, or JAX. Experience designing scalable, production‑ready AI systems in AWS, GCP, or Azure, with a deep understanding of vector databases, model serving, and inference optimization. Familiarity with LangSmith, LangFuse, or equivalent tools for tracking, debugging, and evaluating LLM performance. Expertise in integrating AI systems with RESTful APIs and internal platforms to create seamless, usable products. Preferred Qualifications Experience using LlamaIndex, Hugging Face, or similar open‑source frameworks. Strong understanding of context optimization, embedding strategies, and knowledge retrieval. Familiarity with MLOps, CI/CD pipelines, and production deployment best practices. Prior experience in fintech, payments, or other data‑intensive and regulated industries. Analytical rigor and ability to translate business objectives into measurable AI outcomes. Benefits Competitive Compensation Remote work—work from anywhere. Home Office Bonus—a one‑time allowance to create your ideal home office. Work equipment, stock options, and health plan wherever you are. Flexible days off. Language, professional, and personal growth courses. We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
