Ai/ML Data scientist

Ai/ML Data scientist-Walk In - Chennai

Experiences : 6 to 12 Years

The Role

In this role, you will uncover the insights and intelligence that help customers in dynamic, dataintensive industries operate, scale, and innovate. You will develop robust, futureready machine learning and analytical models that enable predictive insights, automation, and datadriven decision making across complex digital transformation programmes. With access to modern data platforms, highquality datasets, and advanced statistical and AI frameworks, you will work closely with engineering, product, and analytics teams to build solutions that are accurate, explainable, and scalable. This role empowers you to shape endtoend analytical ecosystemsaccelerating delivery, enhancing decision quality, strengthening operational resilience, and guiding organisations toward a more insightrich, AIenabled future.

Your responsibilities:

• Explore, clean, and analyse large, complex datasets to uncover patterns, trends, and opportunities that drive actionable insights.
• Develop, train, and validate machine learning, statistical, and predictive models that solve real business problems and deliver measurable impact.
• Design and run experiments (A/B tests, hypothesis tests, simulations) to evaluate ideas, quantify outcomes, and guide decisionmaking.
• Collaborate with data engineers, analysts, product managers, and domain experts to translate business requirements into welldefined modelling tasks.
• Build endtoend ML pipelinesfrom feature engineering and preprocessing to deploymentready model outputs.
• Apply advanced techniques such as NLP, timeseries forecasting, anomaly detection, optimisation, or LLM/GenAI methods where relevant.
• Implement model evaluation frameworks using offline metrics, crossvalidation, online experiments, and humanintheloop feedback loops.
• Communicate insights clearly through dashboards, visualisations, written summaries, and presentations tailored to technical and nontechnical stakeholders.
• Ensure models are interpretable and explainable where required, providing transparency into key drivers and assumptions.
• Work with engineering teams to deploy models into production, monitor performance, and retrain or recalibrate as data and conditions change.
