In this critical role, you will work with bright and insightful minds, passionate professionals, and a welcoming community where your creative ideas are exceedingly valued.

What You’ll Do

• Design and implement automated MLOps pipelines (data, preprocessing, training, tuning, deployment) for machine learning and LLM/Generative AI models in cloud environments.
• Deploy and optimize deep learning and Generative AI models across web and mobile platforms for enhanced performance and efficiency.
• Integrate and build LLM-driven agentic workflows using existing services and APIs, embedding them into chat-based or autonomous interfaces.
• Develop and maintain modular, prompt-aware components with agent orchestration frameworks like LangChain.
• Implement advanced LLM techniques such as Retrieval-Augmented Generation (RAG), function calling, and memory-aware workflows to support sophisticated agent behaviors.
• Actively participate in code reviews, testing, and champion best software development practices.
• Collaborate cross-functionally with ML engineers, product teams, and other stakeholders to industrialize ML and LLM/Generative AI models and convert domain-specific APIs into LLM-controllable tools.
• Work within an agile framework, contributing to the delivery of high-quality products.
• Foster a culture of continuous learning, collaboration, and improvement within the team.
• Communicate complex technical and business concepts effectively to diverse audiences.

What You’ll Need

• Bachelor’s or Master’s degree in Computer Science or a closely related technical field.
• 3+ years of experience as an ML/LLM Engineer in a cloud development environment.
• Profound understanding of Generative AI architectures and methodologies, including vectorization, context-based retrieval, and LLM operations.
• Demonstrated experience working in an agile/SCRUM development setting.
• Hands-on experience with orchestration frameworks (e.g., LangChain, LlamaIndex, CrewAI, Semantic Kernel) for developing multi-step LLM agents.
• Aptitude for translating complex mathematical and scientific concepts into understandable terms for non-technical audiences.
• Exceptional communication and collaboration skills, with a passion for working in a global team environment.
