Join Energy Vault as a Software Engineering Intern on a highly talented engineering team building and supporting the next generation of our software platform. This internship is designed for a motivated, fast-learning student with a solid foundation in problem solving, software engineering, and an eagerness to work across real production systems.
You’ll work independently, and under guidance, on meaningful tasks while being fully embedded within our engineering team and operating as if you’re a full-time contributor. You’ll gain hands-on experience in software development, automation, integration, and AI-assisted engineering workflows.
This role is estimated to be 2-3 months in duration with 40-hours per week.
Your Mission:
- Work independently and under guidance on scoped software development tasks, contributing production-quality code.
- Support the development and testing of software components using Python and Java.
- Help create automation scripts, tools, and lightweight test frameworks to streamline workflows.
- Collaborate closely with senior engineers and participate in daily standups, design discussions, and code reviews.
- Use modern AI engineering tools (e.g., Claude) to enhance coding, debugging, documentation, and research.
- Help investigate issues, perform debugging, and propose improvements with guidance from the engineering team.
- Learn and apply fundamentals of distributed systems, networking, and energy-related software systems.
- Contribute to documentation, design artifacts, and internal knowledge-sharing resources.
Your Background:
- Pursuing a BS or MS in Computer Science, Computer Engineering, or Electrical Engineering.
- Strong foundation in problem solving, algorithms, and software fundamentals.
- Development experience with Python and/or Java and ability to develop software without using AI tools.
- Ability to work independently and take initiative on assigned tasks.
- Understanding of software development best practices (version control, testing, debugging).
- Interest in distributed systems, cloud platforms, networking, or energy systems.
- Strong communication skills and ability to operate within a fast-paced, high-talent team.
- Exposure to Linux, scripting, or basic cloud concepts (AWS).
- Experience in using or willingness to learn AI-enabled development tools (e.g., Claude).
- Comfortable thriving in fast-paced, rapid growth environments.
- A passion for sustainability, our mission, and our vision is a bonus!
