What You'll Do:

• Apply advanced NLP techniques to extract insights from large proprietary unstructured and structured datasets
• Design, build, and maintain scalable production-ready ML systems
• Participate in the ML model lifecycle, from problem framing to training, deployment, and monitoring in production
• Partner with our ML Operations team to deliver solutions for automating the ML model lifecycle, from technical design to implementation
• Work in a cross-functional team of ML Engineers, Product Managers, Designers, Backend & Frontend Engineers who are passionate about delivering exceptional products

What We Look For:
Outstanding people come from all different backgrounds, and we're always interested in meeting talented people! Therefore, we do not require any particular credential or experience. If our work seems exciting to you, and you feel that you could excel in this position, we'd love to hear from you. That said, most successful candidates will fit the following profile, which reflects both our technical needs and team culture:

• Pursuing a bachelor's degree or higher with relevant classwork or internships in Machine Learning
• Experience in designing and iterating on agentic systems, understanding user interactions, and evaluating agent performance to enhance user experiences.
• Experience with advanced machine learning methods
• Statistical knowledge, intuition, and experience modeling real data
• Expertise in Python and Python-based ML frameworks (e.g.,LangGraph, Pydantic AI, PyTorch)
