NLP Engineer

We are seeking a talented and experienced AI/NLP Engineer to join our dynamic team. The ideal candidate will have a strong background in Artificial Intelligence (AI), Natural Language Processing (NLP) and Machine Learning (ML), with proven expertise in fine-tuning, deploying, and optimizing state-of-the-art NLP models. This role demands a hands-on approach to designing, developing, and integrating NLP solutions tailored to solve complex business challenges. 

If you are passionate about cutting-edge AI, have a knack for deploying scalable models in production environments, and enjoy collaborating with cross-functional teams, we’d love to hear from you! 

Key Responsibilities: 

• Model Development and Fine-tuning: 
  • Customize, fine-tune, and optimize open-source NLP models (e.g., Transformer-based, Conformer-based, and VITS architecture) using transfer learning. 
  • Develop and train models from scratch when needed to address specific business challenges. 
• Generative AI & Prompt Engineering: 
  • Design effective prompts for generative AI tasks to meet diverse user and business requirements. 
  • Build similarity models (e.g., symmetric/asymmetric) using BERT, XLNET, and cross-encoders for LLM-based Retrieval-Augmented Generation (RAG) use cases. 
• Model Deployment & Optimization: 
  • Deploy models at scale using Docker, Kubernetes, and cloud platforms like AWS. 
  • Optimize models for performance using techniques such as vLLM (Paged Attention), quantization, and adapter-based fine-tuning - LoRA, QLoRA. 
• Performance Monitoring and Enhancement: 
  • Continuously evaluate and enhance model performance to ensure accuracy, scalability, and minimal latency. 
  • Build pipelines for data preprocessing, model serving, and monitoring using tools like Airflow and AWS Batch. 
• Collaboration: 
  • Work closely with data scientists, software engineers, and product teams to integrate NLP models seamlessly into business applications. 

Required Skills: 

• NLP & Machine Learning: 
  • 3+ years of experience in NLP, with expertise in fine-tuning, transfer learning, and developing custom models. 
  • Hands-on experience in ASR, TTS, or  custom language model architectures (e.g., Auto-regressive transformers, RWKV). 
• Generative AI & Prompt Engineering: 
  • Proficiency in designing and crafting prompts for generative AI models aligned with business use cases. 
• Programming Skills: 
  • Strong proficiency in Python, with experience in implementing NLP models and building pipelines. 
• Model Deployment: 
  • Hands-on experience with Docker, Kubernetes, and cloud-based deployment on platforms such as AWS. 
• Deep Learning Frameworks: 
  • Proficiency with TensorFlow, PyTorch, and libraries like Hugging Face Transformers, NLTK, SpaCy, and Gensim. 

Bonus Skills: 

• MLOps & Cloud Services: 
  • Experience with AWS (Lambda, Step Functions, Batch), GCP, Azure, or Nemo for model deployment and pipeline management. 
• Large-Scale Deployments: 
  • Expertise in scaling AI models and managing SLAs for real-world applications. 

Preferred Qualifications: 

• Bachelor's or Master’s degree in Computer Science, Data Science, Engineering, or a related field. 
• Proven track record of working with large datasets and creating robust pipelines for data ingestion and preprocessing. 
• Strong understanding of neural networks and advanced deep learning architectures for NLP.
