Job Description
Hinduja Global Solutions (HGS) is a global company specializing in business process management (BPM) and digital customer experience (CX) solutions. HGS offers a range of services including contact center solutions, back-office processing, and integrated digital platforms. They are part of the Hinduja Group, a large multinational conglomerate. With over 20,000 employees across 34 delivery centers in 8 countries, HGS offers a spectrum of technology, digital marketing, and outsourcing solutions tailored to specific industry verticals.
What we are looking for:
Core Skills & Knowledge
- Programming: Expert Python; deep use of Pandas, NumPy, Scikit-learn, PyTorch/Lightning; strong OO and functional patterns.
- Large Language Models: Fine-tuning (LoRA, QLoRA, PEFT), prompt engineering, evaluation (BLEU, BERTScore, hallucination metrics).
- Machine Learning: Classical algorithms (tree-based, linear, ensemble, time-series), hyper-parameter search (Optuna, Ray Tune), model explainability (SHAP, Captum).
- Statistical Methods: Experimental design, p-value and power analysis, Bayesian A/B testing, causal inference.
- Vector Search & RAG: Embedding generation, similarity search tuning (HNSW, IVF-PQ), chunking strategies, knowledge-base hygiene.
- DevOps & Tooling: Git, Docker, Conda/Poetry, make/Task, notebook versioning, automated linting & unit tests (pytest).
- Cloud & Data Platforms: Familiarity with AWS (SageMaker, Bedrock) or Azure (ML, OpenAI) plus modern data warehouses (Snowflake, Redshift, BigQuery) and lake formats (Parquet, Delta).
- Why this role matters
- We deliver data-driven and GenAI-powered products that move business KPIs, not just models. Youll transform raw data and cutting-edge research (LLMs, causal inference, RAG pipelines) into production-grade capabilities that customers use every day.
- Key Responsibilities
Responsibility
Model development & experimentation Build and validate supervised/unsupervised models (classification, regression, clustering) and LLM fine-tuning pipelines; design statistically rigorous experiments (A/B, multivariate, uplift). This also includes RAG applications, and tune RAG workflows with vector databases (pgvector, Milvus) and embeddings (OpenAI, Hugging Face). Optimize retrieval recall, latency, and hallucination rates.
Causal & statistical analysis Apply quasi-experimental methods (DID, propensity scoring, synthetic controls) and hypothesis tests to uncover drivers of business outcomes.
Operationalization & MLOps Package models as reproducible artifacts (MLflow, TorchScript, BentoML), write CI/CD tests, and partner with MLOps engineers on scalable deployment and monitoring.
Data wrangling & feature engineering Build robust ETL/ELT pipelines in Python (Pandas, Polars, SQL) and orchestrate workflows (Airflow, Dagster).
Collaboration & knowledge sharing Translate findings to non-technical stakeholders, contribute to shared notebooks, mentor junior analysts, and document best practices.
Nice-to-Have / Stretch Skills
- Graph data science (Neo4j, Graph-SAGE)
- Streaming ML on Apache Kafka / Flink
- LangChain / LlamaIndex orchestration
- Real-time feature stores (Feast, Tecton)
- Domain knowledge in finance, healthcare, or supply chain
Experience & Education
- 6-10 years of overall IT experience with over 5 years of relevant experience building and shipping ML models or GenAI services in production.
- Proven track record of improving a business metric (conversion, churn, NPS, cost) through data science.
- Bachelors or Masters in Computer Science, Statistics, Mathematics, or related field (or equivalent hands-on experience).
