Senior Data Scientist

The Role:

Joining Moderna offers the unique opportunity to be part of a pioneering team that's revolutionizing medicine through mRNA technology, with a diverse pipeline of development programs across various diseases. As an employee, you'll be part of a continually growing organization, working alongside exceptional colleagues and strategic partners worldwide, contributing to global health initiatives.

Moderna's commitment to advancing the technological frontier of mRNA medicines ensures a challenging and rewarding career experience, with the potential to make a significant impact on patients' lives worldwide. Moderna is solidifying its presence within our international business services hub in Warsaw, Poland, a city renowned for its rich scientific and technological heritage. This hub provides critical functions, meeting the growing demand of Moderna’s global business operations. We're inviting professionals from around the world to join our mission and contribute to the future of mRNA medicines.

As a Senior Data Scientist, you will help shape the future of data science at Moderna by applying advanced machine learning to real-world biotech challenges. You’ll join a high-performing, cross-functional team at the heart of our business operations and product innovation. This role is an opportunity to drive impactful data science strategy while remaining deeply technical—designing, building, and deploying cutting-edge ML systems and tools, with a particular emphasis on NLP, LLMs, and scalable cloud-based architecture.

Expect to work closely with engineers and analysts in developing data-driven solutions that feed directly into Moderna’s platform capabilities. You’ll also mentor junior team members and ensure our machine learning pipelines are production-grade, robust, and efficient.

Here’s What You’ll Do:

Your key responsibilities will be:

• Design, develop, and implement machine learning algorithms and statistical models to solve complex business problems across functions.

• Conduct rigorous experimentation and iterative testing of ML models to drive accuracy, performance, and business alignment.

• Partner closely with Data Engineers and Software Engineers to embed ML solutions in scalable, cloud-based production environments.

• Deliver strategic insights through advanced analytics aligned to business and scientific goals.

• Ensure alignment between model development, deployment processes, and Moderna’s enterprise architecture.

Your responsibilities will also include:

• Champion and guide best practices across the data science lifecycle.

• Mentor junior data scientists and conduct code and model reviews.

• Contribute to internal knowledge sharing and standards development.

• Utilize and optimize modern ML libraries (e.g., scikit-learn, TensorFlow, PyTorch) and CI/CD pipelines for automated model deployment.

• Lead initiatives leveraging Generative AI, NLP, and transformer-based architectures (e.g., prompt engineering, semantic search, and LLM tuning).

• Work with pharmaceutical data platforms such as Veeva (CRM, Vault) and IQVIA.

The key Moderna Mindsets you’ll need to succeed in the role:

• “We digitize everywhere possible using the power of code to maximize our impact on patients.”
  This role is deeply embedded in Moderna’s digital fabric. You’ll be leveraging code-first approaches to create transformative data products, scale intelligent systems, and integrate novel machine learning capabilities into critical functions.

• “We obsess over learning. We don’t have to be the smartest; we have to learn the fastest.”
  To stay ahead in the fast-evolving AI and biotech space, you will need a mindset grounded in relentless curiosity, experimentation, and adaptation—especially as you push into new territory with generative AI and NLP.

Here’s What You’ll Need:

• MS or Ph.D. in Computer Science, Engineering, Physics, or related quantitative fields.

• Deep knowledge of machine learning algorithms, statistics, and data modeling techniques, with 5+ years of hands-on experience.

• Proficiency in Python and experience with ML libraries/frameworks such as scikit-learn, TensorFlow, PyTorch, or similar.

• Experience with ML development on cloud services (AWS, Azure, Databricks, GCP).

• Experience with containerization technologies (e.g., Docker, Kubernetes).

• Knowledge of CI/CD tools (e.g., Jenkins, GitLab CI) and version control systems (e.g., Git).

• Strong experience with SQL and familiarity with handling large datasets, data preprocessing, and feature engineering.

• Excellent ability to clearly communicate complex data science concepts to technical and non-technical stakeholders.

Here’s What You’ll Bring to the Table

• Prior experience working with pharma industry data platforms, especially Veeva (CRM, Vault), IQVIA, or similar platforms.

• Demonstrated expertise in deploying, managing, and monitoring advanced NLP and LLM models

• Deep expertise in transformer architectures, prompt engineering, semantic search techniques, and generative AI applications
