Senior Full Stack Engineer, Growth

Responsibilities

• Design, build, and ship full-stack growth experiments end-to-end
• Improve key metrics across acquisition, activation, engagement, and monetization
• Collaborate daily with product managers, designers, and analysts
• Analyze experiment results and iterate quickly based on data
• Contribute to our experimentation platform and growth infrastructure
• Make thoughtful engineering tradeoffs in pursuit of impact

On a typical week, you might:

• Build and ship an experiment that impacts a core funnel step
• Partner with product, design, and analysts to refine a hypothesis or flow
• Review experiment results and decide what to iterate, keep, or remove
• Improve or extend internal tooling that supports experimentation
• Review code, mentor teammates, and participate in team ceremonies

Requirements

• Strong, hands-on full-stack engineering skills, with the ability to independently design, build, and ship production changes across frontend and backend systems
• Demonstrated experience running product experiments end-to-end
• A data-driven approach to problem solving
• The judgment to balance speed and quality in a growth environment
• Comfort operating in ambiguous problem spaces where the path forward is not fully defined and success is measured by outcomes, not effort
• A collaborative working style and the ability to partner deeply with product, design, and analytics to drive results
• A collaborative mindset and a willingness to give and receive feedback
• Authorized to work lawfully in the United States of America

Nice-to-Haves

• Arrive with clear points of view on what experiments to run, why they matter, and how to evaluate their impact
• Be able to quickly dive into data to uncover growth or monetization opportunities
• Demonstrate ownership beyond implementation, from hypothesis formulation through post-launch analysis and follow-ups
• Have experience scaling growth systems or experimentation platforms in a production environment

Stack

• Backend: Ruby on Rails, Grape, PostgreSQL, Redis
• Frontend: React, TypeScript
• Infrastructure: Google Cloud Platform, Kubernetes, Argo Workflows
