Data Scientist II

Location: USA Remote Status: Fully Remote (#LI-Remote)

LivePerson (NASDAQ: LPSN) is a leader in trusted enterprise conversational AI and digital transformation. The world's leading brands use our award-winning Conversational Cloud platform to connect with millions of consumers. We power nearly a billion conversational interactions every month, providing uniquely rich data analytics and safety tools to unlock the power of conversational AI for better business outcomes. Fast Company named LivePerson the #1 Most Innovative AI Company in the world.

Position Overview

At LivePerson, the Data Scientist II helps advance Conversational AI by applying research and experimentation with Large Language Models (LLMs) to real-world customer interactions. This role designs and executes applied research initiatives, develops effective prompting and orchestration strategies using deep knowledge of transformer architectures, and optimizes modern LLM inference and retrieval pipelines. The scientist analyzes large-scale conversational datasets to improve Retrieval-Augmented Generation (RAG) systems and builds robust experimentation frameworks for evaluating non-deterministic model outputs. Working closely with other scientists and cross-functional teams, this role translates insights on model behavior into recommendations that inform product and business strategy while staying at the forefront of Generative AI advancements.

You Will: Key Responsibilities & Impact

• Propose, plan, and execute applied research initiatives that will make a real-world impact on Conversational AI using Large Language Models (LLMs) within a commercial setting. 
• Use expert knowledge of Transformer architecture mechanics (Attention, Tokenization, Embeddings) to consistently find the most effective, efficient, stable, explainable, and elegant prompting and orchestration approaches. 
• Utilize modern LLM inference and retrieval pipelines. 
• Analyze large scale conversational datasets for RAG (Retrieval-Augmented Generation) optimization. 
• Bring research-inspired prompt strategies to life within production systems. 
• Create durable, flexible scientific evaluation and experimentation capabilities for non-deterministic model outputs. 
• Present findings on model behavior and context efficacy in ways that inform and guide business and product strategy. 
• Work closely with other scientists. 
• Stay current with the rapidly evolving state of Generative AI.

You Have: Required Skills & Qualifications

Requires a Master's degree in Computer Science, Artificial Intelligence, Computational Linguistics, Operations Research, Industrial Engineering, or a directly related field plus two (2) years of experience as a data scientist.

Must have two (2) years of experience in the following (experience may be gained concurrently):

• Programming experience in Python
• Developing and designing Large Language Model (LLM) interaction flows, evaluation frameworks, or advanced prompting strategies
• Partnering with engineering teams to deploy GenAI/LLM solutions into production

Must have one (1) year of experience in the following (experience may be gained concurrently):

• Experience with Generative AI, including Large Language Models, Prompt Engineering, Retrieval Augmented
