As Software Engineer on the Growth team, you’ll partner with PM, design, and data to drive measurable impact on our business. You’ll balance scrappy experimentation with deliberate execution, moving fast when trying new ideas but slowing down when dealing with money.

• Run A/B tests and iterate rapidly, building tooling to improve our experimentation framework
• Own key growth metrics including sign-ups, activation rates, conversion, and retention
• Work across the full stack from frontend to backend to analytics instrumentation
• Partner with PM, design, and data to translate business goals into technical implementations

What you’ll bring

• 3+ years building production web applications with strong full-stack fundamentals
• Proficiency in TypeScript, React, and Node.js (or strong fundamentals in similar technologies)
• Strong product and business sense with motivation to move growth and monetization metrics
• Data-driven mindset with comfort using A/B testing, analytics, and interpreting metrics
• Ability to move fast when experimenting but also slow and deliberately when dealing with credits and payments

• Experience with growth/monetization systems like onboarding, paywalls, referrals, or payment flows (Nice to have)
