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. You’ll own projects end-to-end—from problem scoping, data exploration, model development, and evaluation to deployment and performance monitoring in a fast-paced, experimentation-driven environment.

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.
