• • Your responsibilities will span the full spectrum of product engineering. You will actively support the design and development of innovative AI-driven features, contributing to front-end interfaces, back-end infrastructure, and data processing workflows. A key aspect of your role will involve prototyping and shipping both internal tools and customer-facing applications, leveraging modern web technologies to bring AI solutions to life.
• • This internship offers a unique opportunity to learn product and engineering principles in practice. You will work alongside experienced product managers and engineers to translate complex customer problems into actionable product requirements. You'll gain a deep understanding of how cutting-edge AI models are seamlessly integrated into robust, real-world software systems, bridging the gap between research and application.
• • Collaboration is at the heart of our culture. You will partner effectively with engineers, researchers, and operational teams to rigorously test, iterate, and enhance our AI-driven workflows. Your active participation in design discussions, sprint planning sessions, and code reviews will be crucial in shaping our products and ensuring their continuous improvement.
• • You will also play a vital role in optimizing and refining our deployed applications. This includes assisting with performance enhancements, improving system reliability, and boosting overall usability. Analyzing key data, evaluating the outputs of our AI models, and incorporating real customer feedback will be essential for driving iteration and delivering exceptional user experiences.
• • The impact of your work at Brain Co. will be significant and visible. You will contribute to projects that are modernizing essential government functions, improving patient care in healthcare systems, and optimizing critical industrial infrastructure. Witnessing your code and ideas deployed and utilized by real users, rather than confined to internal demonstrations, provides a profound sense of accomplishment and purpose.
• • To thrive in this role, you should be currently pursuing (or have recently completed) a Bachelor's or Master's degree in Computer Science, Engineering, AI, or a closely related field. You should possess a solid foundation in software development fundamentals, demonstrated through coursework, previous internships, or personal projects. Familiarity with or a strong eagerness to learn technologies such as Python, TypeScript, React, REST APIs, and cloud platforms is highly desirable.
• • We are looking for individuals who are deeply curious about AI systems, possess a keen product sense, and are excited by the prospect of applying machine learning to solve tangible, real-world problems. If you enjoy tackling ambiguous challenges, learning rapidly in fast-paced environments, communicating your ideas clearly, collaborating effectively, and taking ownership of your work, you will find a fulfilling experience at Brain Co.
• • This internship is ideal for those who are eager to contribute directly to impactful problems rather than engage solely in theoretical research. You will gain hands-on experience shipping AI products that operate at a global scale, receive direct mentorship from seasoned engineers, researchers, and former founders, and gain exposure to customer-facing product development in high-stakes environments. You'll be part of a fast-learning culture where your contributions are visible and meaningful.
• • Brain Co. offers an unparalleled opportunity to work on AI systems that drive real-world impact, moving beyond theoretical exercises. You will learn directly from industry leaders with extensive experience at companies like Tesla, DeepMind, and Databricks. You'll build practical expertise with state-of-the-art AI and Large Language Models (LLMs), take on significant responsibilities early in your tenure, and experience rapid growth within a high-impact environment. Our culture is founded on principles of speed, curiosity, and responsibility, making it an exciting place for ambitious individuals.
• • If you are a current sophomore or junior with a passion for applying AI to solve meaningful problems at a global scale, Brain Co. provides the ideal platform to learn, build, and make a lasting impact.
