Engineering Intern

Want to help everyday Americans invest and build wealth? Financial inequality is increasing, and too many people are getting left behind. At Stash, we’re passionate about democratizing wealth creation through education, advice, and products that help customers achieve greater financial freedom. We also believe in working smarter—leveraging AI and emerging technologies to move faster, operate more efficiently, and focus our time on solving meaningful problems for our customers.

As an Engineering Intern, you’ll work alongside experienced engineers, product managers, and designers to build real features that impact our customers.

• Write clean, maintainable, and scalable code

• Help troubleshoot bugs and improve system performance

• Leverage AI-powered development tools to improve coding efficiency, debugging, testing, and documentation

• Experiment with emerging AI technologies and contribute ideas on how AI can improve both the developer experience and customer experience

• Use AI responsibly to accelerate workflows while maintaining strong engineering fundamentals and code quality standards

• Present your work and learnings to the broader organization at the end of the internship

What we're looking for: 

• Currently pursuing a Bachelor’s or Master’s degree in Computer Science, Engineering, or a related technical field

• Expected graduation date between 2026–2028

• Exposure to AI tools such as GitHub Copilot, ChatGPT, Cursor, or similar developer productivity platforms

• Interest in personal finance, investing, or financial technology
