Data Scientist

Overview

Role Overview

In this role, you will help build a lean, production-ready personalization layer for our outbound voice agent.

As India’s leading Voice AI platform, Squadstack has vast experience and data across human and AI voice agent calling. We are building conversational superintelligence - a self learning system to enhance the experience for the end consumers through hyper personalization and hyper contextualization, leading to higher conversions, satisfaction and improved RoI for our clients.

What you'll be doing

• Dive into real conversational data to understand and model what makes interactions feel natural and effective.
• Experiment with machine learning ideas and turn learnings into tangible product upgrades and measurement frameworks, while balancing cost and performance.
• Partner closely with a small, fast-moving team of product leaders, FDEs, data scientists and engineers to ship improvements quickly.
• Continuously raise the bar on conversation quality and outcome conversion through rapid iteration and feedback loops.
• Play a hands-on role in making voice AI agents smarter, more adaptive, more effective and more human over time.
• Learn and iterate rapidly with guidance from experienced advisors.

This is a hands-on high growth role for a data science generalist who can turn ambiguous problems into measurable solutions with strong cost discipline.

What We Want
