AI/ML Engineering Intern

Amperesand is building next-generation power infrastructure systems for Data Centers, EV charging platforms, and future energy applications. Our systems combine advanced power electronics, embedded controls, and scalable energy architectures to rethink how power is converted, controlled, and deployed.

This internship is an opportunity to work hands-on with a startup engineering team that builds and experiments with the latest advancements in AI and Machine Learning. You will contribute to multiple teams, architecting and implementing AI/ML solutions to help improve reliability, and accelerate the development process

You will work closely with engineers, product owners, and internal and external stakeholders who rely on our AI enabled solutions every day. This is a fast-paced, goal-oriented environment where you'll be expected to take ownership of real, production-facing work.

Design and develop AI/ML solutions that accelerate product development and engineering workflows.

Build AI frameworks, agentic workflows, and knowledge assistants that help teams access and utilize engineering data.

Fine-tune, evaluate, and optimize Large Language Models (LLMs) for domain-specific engineering use cases.

Develop Retrieval-Augmented Generation (RAG) applications using engineering documentation, test data, and design knowledge.

Train and deploy machine learning models to support Mechanical Design Engineering and related teams.

Partner with Mechanical, Electrical, Manufacturing, and Software Engineers to solve high-impact business and engineering problems.

Build data pipelines, model evaluation frameworks, and AI experimentation workflows.

Document solutions and contribute production-quality code in a fast-paced startup environment.

Bring a customer-oriented, team-first mindset to a fast-paced startup environment.

Currently pursuing a Bachelor's or Master's degree in Computer Science, Artificial Intelligence, Machine Learning, Data Science, or a related field.

Strong programming skills in Python, Go, Rust, and TypeScript.

Experience with machine learning frameworks such as PyTorch, TensorFlow, Scikit-Learn, or similar.

Familiarity with LLMs, prompt engineering, Evals, and AI agents.

Understanding of machine learning fundamentals, model evaluation, and data processing.

Experience with Git and collaborative software development practices.

Strong communication, problem-solving, and teamwork skills.

Self-motivated, team-oriented, and comfortable working in a fast-paced, ambiguous startup environment.

Available to work on-site.
