Growth Engineer

Role Summary

What is Fizz

Fizz is the hottest Gen Z social platform in the world. Having started as America’s biggest college social app, Fizz is now allowing Gen Z globally to connect around their shared experiences and identities. College Fizz communities feature a private, moderated feed of posts from verified students, making it the most entertaining and authentic way to experience student life. Our newest product, Global Fizz, brings together all of Gen Z both domestically and abroad, providing a space to satisfy the 99% of life not on entertainment platforms like Instagram and TikTok. Fizz is on a mission to bring social back to social media.

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 social app at 700+ colleges, have begun to generate revenue through advertising, and are actively expanding to communities beyond college. Most recently, Fizz hit #1 overall on the App Store charts in Saudi Arabia.

Where We're Going

We have three primary goals for 2026: continue our expansion to the entire US college market, drive revenue growth through our revolutionary ads business, and rapidly expand to non-college students — both domestically and abroad.

Responsibilities

We’re seeking a Growth Engineer to build the systems and automations that power Fizz’s expansion, monetization, and operational efficiency. In this role, you’ll sit at the intersection of product, engineering, and go-to-market — working directly with our Head of Product, CTO, growth, and monetization teams.

You’ll own high-leverage projects across GTM, content management, trust & safety, and monetization, designing systems that eliminate manual work and accelerate our growth.

Specifically, your responsibilities will include

• Build systems that drive growth: Design and maintain the internal tools, workflows, and automations that power Fizz's GTM engine, from onboarding flows to campus launch execution — built as real services with clear data models, APIs, and job pipelines, not one-off scripts.
• Enable operational excellence: Collaborate with ops and trust & safety teams to identify recurring issues, ship quick fixes, and deliver scalable solutions that improve efficiency and reduce pain points.
• Turn data into leverage: Own analytics pipelines, dashboards, and reporting. Write SQL queries, track performance metrics, and ensure teams have accurate and actionable insights.
• Automate the unglamorous stuff: From internal content workflows to systems that manage performance of 500+ Instagram page managers on campus, take on critical but messy challenges that unlock scalability.
• Requirements shaping: You don’t just wait for specs — you proactively talk to ops, growth, and product teams to uncover problems, scope opportunities, and define what should be built.
• Experiment and ship quickly, then make it last: Prototype fast with LLM-driven workflows, then own the path from prototype to production yourself. You should have the judgment to know when a scrappy tool is good enough and when you should rebuilt it as a durable backend system — with real data models, idempotency, monitoring, and error handling.
• Be accountable for outcomes: Your work directly impacts Fizz’s ability to expand faster, monetize smarter, and operate more efficiently.

Requirements

• 2+ years of experience in backend-heavy software engineering (growth, infra, or product-engineering)
• Proven track record of building technical systems or products from 0→1 in fast-paced environments
• Strong backend fundamentals: data modeling, API design, queues, background jobs, caching — with hands-on experience architecting and operating services in a cloud environment (GCP, AWS, Azure)
• Exceptional communication skills to translate between technical and non-technical stakeholders
• Highly data-driven, with the ability to dive deep into analytics while also shaping strategic outcomes
• Fluent with AI coding tools, and able to read, review, and debug what they produce.
• Strong grasp on the psychology of social products and a passion for building authentic experiences for Gen-Z
• The primary technologies we work with are Swift/Kotlin, Node, Google Cloud, BigQuery, MongoDB, and Redis — but no prior experience with these specific technologies is required.
• This is an onsite role based out of our New York, NY (Soho) office.
• The targeted compensation range for this role is between $130,000 - $170,000 a year, based on job related skills and experience.
• Fizz full-time employees are eligible for company sponsored benefits and equity.
