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.

This position is an onsite role based out of our New York City office. Relocation assistance may be available for the right candidate.

Where We’re Headed

Responsibilities

• Design, build, and maintain core app infrastructure and shared components to support scalable and maintainable product development
• Set up tools and processes that promote fast, high-quality software development and strong engineering culture

Qualifications

• Strong experience with Swift, SwiftUI, and UIKit
• Demonstrated ability to build and ship production-quality iOS apps from 0 to 1, ideally in a startup or fast-paced environment
• Experience working with RESTful APIs, and comfort collaborating with backend engineers —or contributing directly to backend code when needed
• Understanding of core iOS platform concepts, such as app lifecycle, data persistence, concurrency, and performance optimization
• Awareness of common security and privacy best practices from a developer perspective
• Strong product intuition and a pulse on Gen Z user behavior — able to build features that are both delightful and impactful
