How you will make an impact :- Analyze complex, large-scale datasets to uncover patterns, trends, and opportunities that translate into actionable insights and measurable business value
- Design, develop, deploy, and maintain predictive models and machine learning solutions supporting business and operational use cases
- Build AI-powered applications and AI agents leveraging Large Language Models (LLMs), prompt engineering, retrieval-augmented generation (RAG), orchestration frameworks, and tool integration
- Research, evaluate, and prototype emerging AI, machine learning, and agentic technologies and assess their applicability within telecom and networking environments
- Develop solutions supporting network operations, automation, incident analysis, anomaly detection, knowledge assistance, customer support, and decision support
- Partner closely with cross-functional stakeholders to define use cases, translate requirements, and deliver scalable, production-ready solutions
- Define and apply evaluation methods and performance metrics for machine learning and LLM-based systems, including quality, reliability, latency, and business impact
The must haves:- Bachelor’s degree or higher in Computer Science, Data Science, Statistics, Engineering, Physics, or a related quantitative field
- Proven experience in a Data Scientist, Machine Learning Engineer, Applied Scientist, or similar role
- Strong proficiency in Python and hands-on experience with data science and machine learning libraries
- Experience building and deploying machine learning models in production or near-production environments
- Practical experience with Large Language Models (LLMs) and generative AI applications, including prompt engineering, model integration, or retrieval-augmented generation (RAG)
- Solid understanding of AI agent concepts including orchestration, tool use, planning, memory, guardrails, and human-in-the-loop approaches
- Strong foundation in data structures, software design, system architecture, and analytical problem-solving
Nice to haves:- Experience working with cloud platforms such as Amazon Web Services (AWS), Google Cloud Platform, or Microsoft Azure
- Familiarity with Linux-based environments, shell scripting, and containerization technologies such as Docker and Kubernetes
- Experience with data and machine learning frameworks including SQL, Pandas, Spark, scikit-learn, XGBoost, TensorFlow, MLflow, Kedro, or similar tools
- Exposure to generative AI and LLM ecosystems such as LangChain, LangGraph, Hugging Face, vector databases, or related technologies
- Experience with monitoring, evaluation, and observability for machine learning or LLM-based systems
- Familiarity with data visualization, reporting tools, Agile development practices, and CI/CD pipelines
- Domain knowledge in telecom, networking, OSS/BSS, network assurance, or service operations
