Comfort designing and interpreting experiments, and working with ambiguous or evolving requirements

Responsibilities

• Concevoir, construire et tester des expériences client, y compris des recommandations, des campagnes de fidélisation, des flux de réservation et des mises à niveau de plan.
• Exécuter des expériences structurées (tests A/B, déploiements progressifs) pour valider si un changement améliore la conversion, l'adoption ou la rétention.
• Ability to mentor engineers to maximize their performance and impact
• Experience leveraging AI tools or systems to accelerate development, improve testing, and deliver new product capabilities

Requirements

• Successful applicants typically have 8+ years of software development experience
• A product-minded engineer who starts from the customer problem and the metric that matters, not just the ticket, and is comfortable proposing a different approach when the data calls for it
• Experience owning multi-quarter projects that solve complex engineering problems and make measurable customer impact at scale
• Experience with large-scale refactors, performance and reliability issues, and a strong sense of ownership over all aspects of your product area
• Experience in, or interest working in, Ruby on Rails, React, GraphQL, and TypeScript
