About The Role The Platform Experience team plays a critical role in driving organizational growth by optimizing

Time-to-Productivity (TTP) metrics across the platform. Our mission is to create seamless, high-impact experiences that accelerate customer success and increase trial-to-paid conversions. We own and evolve two mission-critical growth products:

Onboarding – A no-code/low-code guided experience that enables customers to quickly set up and derive value from the platform.

Launchpad – A conversion-focused enablement engine that helps customers activate key features efficiently. Both products are continuously optimized through

data-driven experimentation and A/B testing , allowing us to identify and implement the most effective solutions for customer conversion and retention. Additionally, we own

Global Search , a high-performance system that enables users to search anything across the platform in fractions of a second, ensuring speed, reliability, and discoverability at scale. Our systems directly impact growth, engagement, and customer satisfaction—making stability, performance, and engineering excellence non-negotiable.
