About the role

You will work on a broad range of cutting-edge data science and machine learning problems across a variety of industries. You will be engaging with clients to understand their business context. If you are passionate about working on complex unstructured business problems that can be solved using data science and machine learning, we would like to talk to you.


Responsibilities:

  • Architect, develop, and deploy machine learning models and AI solutions into live production settings.
  • Partner with data scientists to convert prototypes into scalable, enterprise-ready applications.
  • Design and implement enterprise AI systems leveraging LLMs, retrieval-augmented generation (RAG), knowledge graphs, and multi-agent orchestration.
  • Embed AI models into existing products, APIs, and broader enterprise systems seamlessly.
  • Perform rigorous experimentation, fine-tuning, and error analysis to boost model accuracy and reliability.
  • Continuously monitor, maintain, and retrain deployed models to sustain optimal performance.
  • Keep abreast of the latest developments in AI/ML, MLOps practices, and cloud-native AI technologies.
  • Collaborate with stakeholders to translate business challenges into effective AI-driven solutions.
  • Uphold ethical standards and responsible AI principles throughout the AI lifecycle.


Requirements:

  • Strong programming skills in Python (TensorFlow, PyTorch, scikit-learn) and GenAI frameworks (LangGraph, AutoGen, OpenAI SDK, etc. ) and prompt engineering on foundation models (OpenAI, HuggingFace, Anthropic, etc. )
  • Knowledge of NLP, computer vision, or generative AI (LLMs, diffusion models, RAG, fine-tuning models, conversational AI, knowledge graphs, etc.
  • Familiarity with cloud AI services (AWS SageMaker, Azure ML, GCP Vertex AI).
  • Solid understanding of data structures, algorithms, and software engineering principles.
  • Hands-on experience with model deployment (APIs, microservices, real-time inference).
  • Mandatory Skills: Python, Generative AI, Tensorflow, Pytorch, LLM, LangChain, Forecasting, Statistical Methods, NLP, vector databases, RAG architectures, MLOps tools (MLflow, Kubeflow, Airflow, Docker, Kubernetes), cloud AI platforms (AWS SageMaker, GCP Vertex AI, Azure ML
  • Strong learning acumen.
  • High sense of ownership.
  • Ability to work in a fast-paced and deadline-driven environment.
  • Loves technology.
  • Highly skilled at Data Interpretation.
  • Problem solver.


Nice-to-Have:

  • Experience with MLOps tools (MLflow, Kubeflow, Airflow, Docker, Kubernetes).
  • Experience with big data technologies (Spark, Hadoop, Databricks).
  • Exposure to responsible AI frameworks and bias detection methods.
  • Contributions to open-source AI/ML projects.


Desired Experience and Education:

  • 3 - 5 years of relevant Machine Learning experience.
  • B. Tech from a Tier-1 college / M. S or M. Tech is preferred in Computer Science, Information Technology, or a similar degree.
