So, it doesn't matter where you are; Since our launch, Proxify's developers have successfully worked with 1200+ happy clients to build their products and growth features. Proxify is shaped by a global network of supportive, talented developers interested in remote full-time jobs. We are looking for a Senior Data Scientist (Python) to join one of our high-growth client teams as a technical lead in data innovation. In this role, you will be responsible for transforming complex, high-velocity datasets into predictive models and actionable systems that directly influence product strategy and business operations. You will bridge the gap between pure research and production software engineering. You will not just build prototypes in notebooks; you will design, train, evaluate, and deploy robust machine learning models into live cloud environments. This is a role for a systems-thinking data scientist who values clean, modular Python architecture, statistical rigor, and scalable data pipelines.

Strong proficiency in writing complex, optimized SQL queries and experience handling large-scale data using distributed computing frameworks like Py Spark or Ray. Experience with machine learning lifecycle tools (such as MLflow, DVC, or Weights & Biases ) for model tracking, versioning, and feature store management.
Hands-on experience leveraging cloud data infrastructure (AWS, GCP, or Azure) and managed ML services (e.g., Sage Maker or Vertex AI). CET (+/- 3 hours). Deep Learning experience using Py Torch or Tensor Flow/Keras . Experience with NLP frameworks (Hugging Face, spa Cy) or deploying LLM-based pipelines (Lang Chain, vector databases). Familiarity with orchestration tools l
