YOUR ROLE As a Product Engineer in our Growth (Land & Expand) department, you will own and build end-to-end customer-facing web applications that help users seamlessly discover, book, and expand their car subscription fleets. Joining our team early on, you will operate with high autonomy to transform initial ideas into frictionless digital experiences, directly influencing how thousands of customers interact with our e-commerce platform. YOUR MISSION You will own the optimization of our discovery and checkout journeys, rapidly shipping customer experience improvements that directly lift onboarding success and booking conversion rates. You will drive fast-paced product iterations by taking feature briefs from early concepts to live production environments, keeping technical implementations simple and impactful. You will run continuous experiments and A/B tests to validate new initiatives, such as building configuration comparison features that help customers evaluate their vehicle options.
