At SentiSum, we’re building the AI-native Voice Of Customer platform, helping top consumer brands understand why customers churn and what to do about it. We turn noisy support tickets, reviews, chats, and surveys into clear retention signals.
As a Senior Backend Product Engineer , you’ll play a pivotal role in scaling the systems behind that intelligence, working across data pipelines, event-driven architecture, and product logic to deliver real outcomes. You won’t just build APIs, you’ll help shape features that drive revenue, retention, and product excellence.
What you’ll do
- Own and evolve core backend systems, from data ingestion to product logic
- Design scalable, event-driven services that power real-time insights
- Work closely with Product, AI, and Frontend to bring new features to life
- Help simplify architecture, reduce tech debt, and improve performance
- Contribute to key engineering decisions and mentor where needed
