Senior AI/ML Engineer

About the job

JOB SUMMARY We are seeking a Senior AI/ML Engineer to lead the research, design, and development of advanced machine learning models and algorithms. This role focuses exclusively on the model development lifecycle—including architectural design, training methodology, optimization techniques, and algorithmic innovation—while collaborating with MLOps teams for production deployment. CORE RESPONSIBILITIES: • Design and architect neural network models including Transformers, CNNs, RNNs, and hybrid architectures; make decisions on layer configurations, attention mechanisms, activation functions, and connectivity patterns for optimal performance. • Develop and implement training algorithms and optimization strategies including custom loss functions, learning rate schedules, gradient clipping, and regularization techniques to ensure stable convergence and generalization. • Fine-tune pre-trained foundation models (LLaMA, Mistral, BERT, GPT, T5) using Parameter-Efficient Fine-Tuning(PEFT) methods including LoRA, QLoRA, Prefix Tuning, and AdaLoRA for domain-specific applications.
