Sr. Backend Engineer in NEW YORK CITY METROPOLITAN AREA

Software Engineer [Backend]

What is Fizz

Fizz is the dominant social platform for Gen-Z to connect with their immediate communities. Each Fizz community has a private and moderated feed of anonymous posts, authored by verified students at their school, providing the most entertaining, relatable, and interesting conversations about student life.

Students can post questions, memes, polls, and chat with other verified students while maintaining control over their identity and privacy. Fizz communities prioritize safety, authenticity, and inclusion through community-based moderation.

Founded by two Stanford dropouts, Fizz is currently expanding across colleges and high schools across the US with a mission to redefine the “social network” in a time when legacy platforms lack authenticity and are filled with curated highlight reels.

What we’ve done

We first launched Fizz at Stanford in July 2021 and have since seen >95% of undergraduates join the app, half of which use Fizz every day. Since raising a $25M Series B in July 2023, we have established ourselves as the dominant community platform at 350+ colleges, have begun to generate revenue through partnerships, and are actively expanding to communities beyond college.

Where we’re going

We have three primary goals for 2025: continue our expansion to the entire US college market, drive revenue growth through continuous product iteration, and build products to expand our user base and become the dominant social platform for all of Gen-Z, not just US college students.
