As a Senior Software Engineer on the team, you'll own the technical design and delivery of features across Experiments, Feature Flags, Session Replay, and Heatmaps.

You'll partner directly with Product and Design to shape where these products go next, and collaborate with teams like AI Engine and Product Platform on shared systems and the SDKs that power our products.
