About Arctan At Arctan, we’re on a mission to eliminate communication barriers in global conversations. We’re the first and only company in India building low-latency speech AI models that refine how people sound while they speak. We help customer-facing global teams speak with clear English accents and connect across cultures. This is a defining moment in voice augmentation, and we’re at the forefront of it. Role Overview As a Data Science Intern, you will play a key role in improving and optimising the models that drive Arctan’s real-time speech AI. You’ll work on analysing, processing, and modelling data to make our systems smarter. Specifically, you’ll: Develop and fine-tune Speech to Speech machine learning models Experiment with data-driven solutions to enhance AI performance. Work on feature engineering and dataset preparation to train robust models. Collaborate with the team to evaluate and deploy models into production. What we’re looking for You don’t have to be an expert yet, but you should have: Strong problem-solving skills, paired with a passion for learning. Proficiency in Python and familiarity with data science libraries. Basic understanding of machine learning frameworks (e.g., TensorFlow, PyTorch). Familiarity with working on datasets and data preprocessing techniques. Experience with speech processing or NLP is a bonus but not required. Why this is interesting During this internship, you’ll be building parts of the system that matter. You’ll see your work in action and learn how startups use data to create transformative products. You’ll also gain exposure to cutting-edge AI techniques and tools, preparing you for a career in data science/machine learning. Other Details Location: Bengaluru Duration: 3-6 months  This is a paid internship.
