Machine Translation Researcher (NMT&LLMs), Mumbai

Job Title: Machine Translation Researcher (NMT&LLMs) Degrees in Computational Linguistics or CS degrees. Location: Fully Remote– India Reports To: VP of AI Employment Type: Full-time ________________________________________ About the Role We are looking for a highly experienced Machine Translation Researcher to join our team and drive innovation inNeural Machine Translation (NMT) and LLM-based translation systems . This is a fully remote, long-term position, allowing you to live and work from anywhere while collaborating with a global team. In this role, you will design, train, and deploy state-of-the-art machine translation models, work with large-scale multilingual datasets, and integrate advanced LLM-based translation and RAG pipelines into production workflows. You will also help push the boundaries of translation quality, particularly for low-resource languages and domain-adapted MT systems.This position is ideal for researchers who combine strong theoretical understanding of modern NLP architectures with hands-on experience building and deploying large-scale MT systems. ________________________________________ Key Responsibilities: Machine Translation Research&Development• Design, train, fine-tune, and evaluate Neural Machine Translation (NMT) models across multiple language pairs (both high- and low-resource languages). • Develop state-of-the-art Transformer-based encoder–decoder models for production translation systems. • Conduct research and experimentation in areas such as:o Domain Adaptation o Knowledge Distillation o Factored MT o Adaptive NMT o Low-resource MT with LLM augmentation• Improve model robustness, generalization, and domain specialization. LLM-Based Translation Systems • Fine-tune and adapt large language models for translation tasks, including:o Qwen o DeepSeek o LLaMA• Apply LoRA / QLoRA and other parameter-efficient fine-tuning methods for multilingual MT tasks. • Build RAG-based translation pipelines using domain-specific knowledge sources. • Design prompting strategies and translation prompting frameworks for LLM-assisted translation workflows.Architecture&Modeling• Design and implement custom Transformer architectures and enhancements such as: o Additional Quality Estimation (QE) heads o Multi-stage LLM chaining pipelines o Hybrid NMT + LLM translation systems • Experiment with scalable architectures for multilingual and low-resource language translation.________________________________________ Required Qualifications Education• Bachelor's or Master's degree in one of the following: Computational Linguistics, Language Technology, Computer Science, Artificial Intelligence or a related field with equivalent experience.
