Staff Data Scientist

Paddle offers digital product companies a completely different approach to their payment infrastructure. Instead of assembling and maintaining a complex stack of payments-related apps and services, we’re a Merchant of Record for our customers. That means we take away 100% of the pain of payment fragmentation. It’s faster, safer, cheaper, and, above all, way better. We’re backed by investors including KKR, FTV Capital, Kindred, Notion, and 83North and serve over 5000 software sellers in 245 territories globally.

As a Staff Data Scientist, you will identify and drive new strategic opportunities, such as pricing, support automation, and KYB automation, through advanced machine learning models and analytics. You will design comprehensive systems, including data capture, operational processes, experimentation frameworks, and feedback mechanisms. You'll lead end-to-end model development and deployment processes, leveraging classical ML methods (boosted trees, neural networks, regressions) and LLM based methods based on agentic AI. You will collaborate across teams to ensure seamless integration and productionization of solutions that significantly impact business performance.

What you’ll do:

• Work with different teams in order to identify and research opportunities to use AI and ML opportunities in order to generate business value.
• Leverage a wide range of machine learning techniques, including boosted trees, neural networks, regressions, to solve problems such as pricing optimization or mining of insights of customer support queries.
• Explore and implement state-of-the-art agentic AI and Large Language Model (LLM) solutions to automate and enhance processes.
• Conduct rigorous experimentation, testing, and validation to optimize model performance and ensure alignment with business objectives.
• Collaborate closely with cross-functional teams, including Product Management, Analytics Engineering, Platform Engineering, and Customer Operations, to operationalize data-driven solutions.
• Act as a mentor and technical leader, advocating for best practices in model development and deployment.
• Continuously monitor and iterate on models in production, maintaining high standards for accuracy and performance.
• Partner with business units to help evaluate AI solutions and to build systems which generate business impact.
• Design, develop, and deploy machine learning models into production, ensuring scalability, reliability, and maintainability.

We’d love to hear from you:

• Proven track record of successfully deploying machine learning models into production environments.
• Extensive experience with classical ML techniques (boosted trees, neural networks, regressions, clustering, etc.).
• Demonstrated expertise with agentic AI, prompt engineering, and leveraging Large Language Models (e.g. LangChain / Graph).
• Proficiency in Python and key data science libraries (e.g., Pandas, NumPy, Scikit-learn, TensorFlow, PyTorch).
• You are an industry expert in Model development, deployment and MLOPs practices.
• Strong analytical and problem-solving abilities coupled with sound business judgment.
• Excellent communication skills, capable of engaging both technical and non-technical stakeholders effectively.
