Growth Notifications aims to drive critical business metrics (e.g. DAU/MAU, story views) through relevant, timely, and personalized but unsolicited communications (‘nudges’) through suitable available channels (e.g. app push, email, sms) in a cost‑effective manner while maintaining data accuracy and platform integrity. We drive user growth and engagement by helping the user discover timely, relevant, and personalized content that entices the user to repeatedly come back to the platform and engage in retentive activities.

We use interruptive communication channels such as app push notifications, smses, and emails, which demand immediate user attention, and as such, are highly effective in driving user action.

• Deep experience with observability (metrics, logging, tracing, dashboards) and using data to debug, harden, and evolve large‑scale systems.
• Excellent collaboration and communication skills; able to work effectively with Product, DS, ML, Design, and other engineering teams to align on requirements and trade‑offs.
• Ability to mentor and uplevel engineers, provide clear technical guidance, and create structures that make the team more effective over time.
