Software Engineering Intern (Fall 2025)

About Fizz

Fizz is the go-to social platform for Gen Z to connect with their community. College Fizz communities feature a private, moderated feed of anonymous posts from verified students, making it the most entertaining and authentic way to experience student life. On Global Fizz, all of Gen Z can connect across their shared experiences and identities.

Users can ask questions, share memes, post polls, and direct message others—all while keeping control of their identity. Safety, inclusion, and authenticity are core to everything we build.

Founded by two Stanford dropouts, Fizz launched at Stanford in 2021 and quickly reached over 95% student adoption. Since then, we've expanded to 400+ colleges, started generating ad revenue, and raised >$40M from investors such as Lightspeed, NEA, and Owl. Our mission: build a social network for the 99% of life that doesn’t make it onto entertainment platforms like Instagram and TikTok.

Where We’re Headed

In 2025, we’re focused on:

• Expanding to every U.S. college

• Accelerating revenue through new product iterations

• Expanding Fizz to new markets beyond college, leveraging the new version of the Fizz product - Global Fizz

As a Fizz intern, you will be able to use your own experience of being a Fizz user to directly build for a product you care about. If you are proactive and driven to tackle challenging technical problems, have a passion for crafting high-quality software, and are eager to learn quickly and build new products from scratch , this internship is perfect for you. Interns will be compensated financially (including a housing stipend) and work full time out of our NYC office. We are flexible with start and end date of the internship.
