Are you ready to redefine the future of customer service with the power of AI?
We're looking for a Senior Data Scientist who doesn't just build models-but helps define how data drives our business. In this role, we use advanced machine learning and statistical techniques to solve complex problems, unlock new opportunities, and shape the future of our products and decisions.

As a senior member of the team, we count on you to lead end-to-end initiatives across the full data science lifecycle-from framing ambiguous problems and exploring data to developing, deploying, and continuously improving models in production. You'll partner closely with engineering, product, and business leaders to turn ideas into scalable, high-impact solutions.

This role goes beyond execution. We're looking for someone who can influence strategy, guide data-informed decision-making at multiple levels of the organization, and help prioritize where data science can drive the most value. You'll have a voice in shaping our roadmap, defining best practices, and elevating how we operate as a team.

We build with purpose. Together, we focus on delivering solutions that create measurable business impact, improve customer experiences, and position data as a core strategic asset. You'll also play a key role in mentoring others and raising the bar for technical excellence and collaboration.

We're especially interested in someone with strong experience across descriptive, predictive, and prescriptive analytics-someone who can both enhance existing products and help us design and scale what comes next.

We pride ourselves on encouraging a culture of innovation, advocating for agile methodologies, and promoting clarity in all that we do. Join us in embodying the spirit of the 'Un-carrier' and make a tangible impact! If you are passionate about driving excellence and want to make a significant impact, apply today!
