Data Scientist / AI Engineer

Job Description

Who are we

Fulcrum Digital is an agile and next-generation digital accelerating company providing digital transformation and technology services right from ideation to implementation. These services have applicability across a variety of industries, including banking & financial services, insurance, retail, higher education, food, healthcare, and manufacturing.

About the Role

We are looking for a skilled and hands-on Data Scientist with 4–5 years of experience in developing and deploying machine learning models—ranging from traditional ML algorithms to advanced deep learning and Generative AI systems. The ideal candidate brings a strong foundation in classification, anomaly detection, and time-series modeling, along with hands-on experience in deploying and optimizing Transformer-based models . Familiarity with quantization , fine-tuning , and RAG (Retrieval-Augmented Generation) is highly desirable.

Responsibilities

• Design, train, and evaluate ML models for tasks such as classification, anomaly detection, forecasting, and natural language understanding.
• Build and fine-tune deep learning models, including RNNs, GRUs, LSTMs , and Transformer architectures (e.g., BERT, T5, GPT).
• Develop and deploy Generative AI solutions , including RAG pipelines for use cases such as document search, Q&A, and summarization.
• Perform model optimization techniques such as quantization for improving latency and reducing memory / compute overhead in production.
• Optionally fine-tune LLMs using Supervised Fine-Tuning (SFT) and Parameter-Efficient Fine-Tuning (PEFT) methods like LoRA or QLoRA .
• Define and track relevant evaluation metrics; continuously monitor model drift and retrain models as needed.
• Collaborate with cross-functional teams (data engineering, backend, DevOps) to productionize models using CI / CD pipelines.
• Write clean, reproducible code and maintain proper versioning and documentation of experiments.
