The Role

Veeva is a mission-driven organization that aspires to help our customers in Life Sciences and Regulated industries bring their products to market faster. We are shaped by our values: Do the Right Thing, Customer Success, Employee Success, and Speed. Our teams develop transformative cloud software, services, consulting, and data to make our customers more efficient and effective in everything they do. Veeva is a work anywhere company. You can work at home, at a customer site, or in an office on any given day. As a data scientist, you will work for a company focused on making a positive impact on its customers, employees, and communities. This role is a pillar in the Veeva system landscape that envisions 'Connecting life sciences and key people to improve research and care.' Our product offers real-time academics, social, and medical data to build comprehensive profiles. These profiles help our life-science industry partners find the right experts to accelerate the development and the adoption of new therapeutics. We accelerate clinical trials and equitable care. We are proud that our work helps patients receive their most urgent care sooner. Your role will primarily involve developing LLM-based agents that are specialized in searching and extracting detailed information about Key Opinion Leaders (KOLs) in the healthcare sector. You will craft an end-to-end human-in-the-loop pipeline to sift through a large array of unstructured medical documents—ranging from academic articles to clinical guidelines and meeting notes from therapeutic committees. These agents will be equipped to perform semantic searches and provide precise answers to predefined queries concerning KOL-related data across various languages and disciplines. Utilizing cloud infrastructure, you will build models capable of information extraction and question answering. You will also collaborate with a dedicated team of software developers and DevOps engineers to refine these models and deploy them into production environments.

What You'll Do

1. Adopt the latest technologies and trends in NLP to your platform
2. Develop LLM-based agents capable of performing function calls and utilizing tools such as browsers for enhanced data interaction and retrieval
3. Experience with Reinforcement Learning from Human Feedback (RLHF) methods such as Direct Preference Optimization (DPO) and Proximal Policy Optimization (PPO) for training LLMs based on human preferences
4. Design, develop, and implement an end-to-end pipeline for extracting predefined categories of information from large-scale, unstructured data across multi-domain and multilingual settings
5. Create a robust semantic search functionality that effectively answers user queries related to various aspects of the data
6. Use and develop named entity recognition, entity-linking, slot-filling, few-shot learning, active learning, question/answering, dense passage retrieval, and other statistical techniques and models for information extraction and machine reading
7. Deeply understand and analyze our data model per data source and geo-region and interpret model decisions
8. Collaborate with data quality teams to define annotation task metrics, and perform qualitative and quantitative evaluation
9. Utilize cloud infrastructure for model development, ensuring seamless collaboration with our team of software developers and DevOps engineers for efficient deployment to production

Requirements

1. 4+ years of experience as a data scientist (or 2+ years with a Ph.D. degree)
2. Master's or Ph.D. in Computer Science, Artificial Intelligence, Computational Linguistics, or a related field
3. Strong theoretical knowledge of Natural Language Processing, Machine Learning, and Deep Learning techniques
4. Proven experience working with large language models and transformer architectures, such as GPT, BERT, or similar
5. Familiarity with large-scale data processing and analysis, preferably within the medical domain
6. Proficiency in Python and relevant NLP libraries (e.g., NLTK, SpaCy, Hugging Face Transformers)
7. Experience in at least one framework for Big Data (e.g., Ray, Spark) and one framework for Deep Learning (e.g., PyTorch, JAX)
8. Experience working with cloud infrastructure (e.g., AWS, GCP, Azure) and containerization technologies (e.g., Docker, Kubernetes) and experience with bash scripting
9. Strong collaboration and communication skills, with the ability to work effectively in a cross-functional team
10. Used to start-up environments
11. Social competence and a team player
12. High energy and ambitious
13. Agile mindset

Nice to Have

1. Background in Medical NLP
2. Experience with training, fine-tuning, and serving Large Language Models
3. Experience in life/health science industry, notably pharma
4. Having published in AI space in a peer-reviewed journal
5. Production-grade development skills
6. Leadership skills and a solid network to help in hiring and growing the team
7. Experience with NoSQL databases, especially MongoDB
8. Familiarity with model registry solutions such as MLflow
9. Familiarity with distributed computing platforms such as Ray and Spark

Perks & Benefits

1. Personal development budget
2. Veeva charitable giving program
3. Fitness reimbursement
4. Life insurance + pension fund
