About the role

We're building the next generation of AI-native product experiences, where conversations turn directly into outcomes.
As a Senior Software Engineer on the Activation team, you'll work at the intersection of product, growth, and systems - owning the engineering of features that directly shape how users activate, retain, and spread the product.You'll work across the full lifecycle of growth initiatives, from the design of scalable backend systems that power sharing and onboarding infrastructure to the experimentation layer that lets the team learn fast and iterate with confidence.
This role requires balancing deep systems thinking with product intuition, ensuring that what we build is not only technically sound, but measurably moving the metrics that matter.You'll partner closely with product, design, and data to drive initiatives end-to-end - from framing the problem and defining success metrics, through launch and metric readout - and set the technical standard for how the team builds.
