• Take shared ownership of product quality and system health. You'll participate in our on-call rotation — all engineers take a 24/7 week-long shift roughly once a quarter.

• Enjoy solving problems that directly impact business metrics. Bonus: you understand growth domain challenges and have experience working on a growth team — maybe you've built referral systems, optimized conversion flows, onboarding or implemented experimentation frameworks.
• Comfortable with data and analytics — you can set up tracking, analyze experiment results, and make data-driven decisions about feature development and optimization.

• Led significant frontend initiatives or projects, bringing clarity and direction to complex problems and guiding work from early exploration through to delivery.

• Thrive in remote, async environments. You communicate clearly, support your teammates, and don’t wait for permission to make progress.
• Product-minded and user-oriented — you think beyond the ticket, consider edge cases and user experience, and bring a strong sense of ownership to your work.
• Comfortable working with backend code when needed, and you understand how frontend decisions connect to the bigger picture.
• Fluent with AI tools and use them to work with more leverage and level up your own efficiency.
• Likely been doing this for 7+ years, but depth matters more to us than a specific number.
