Requirements

We’re looking for a Data Scientist (3 – 7 years’ experience) who can design and build scalable data-driven solutions, work with large datasets, and collaborate closely with product, engineering, and ML infrastructure teams.

Responsibilities

  • Collaborate with cross-functional teams to identify high-impact business problems that can be solved with data.
  • Design and develop predictive models, statistical algorithms, and machine learning solutions.
  • Own the full lifecycle of model development: data wrangling, feature engineering, training, validation, testing, and deployment.
  • Drive experimentation and A/B testing frameworks to validate hypotheses and measure model impact.
  • Ensure reproducibility, scalability, and reliability of data science workflows in production.
  • Communicate insights and recommendations clearly to stakeholders through visualizations and storytelling.
     

What We’re Looking For

  • 3–7 years of experience in data science or machine learning roles.
  • Strong programming skills in Python and deep understanding of libraries like Pandas, NumPy, Scikit-learn, and PyTorch/TensorFlow.
  • Solid knowledge of statistics, probability, and machine learning algorithms.
  • Experience with SQL and working with structured and unstructured data at scale.
  • Familiarity with deployment pipelines, APIs for model serving, and observability tools is a plus.
  • Curiosity-driven mindset with a bias for action and experimentation.
