You’ll build components within scalable architectures that process customer interaction data, applying generative AI techniques to surface meaningful patterns and insights used by everyone from frontline associates to senior leadership.

The team operates with a culture of psychological safety, rapid incremental delivery, and genuine investment in personal growth. You’ll collaborate with product managers, UX designers, and business stakeholders to translate requirements into well-scoped technical solutions, while also helping raise the quality bar through thorough code reviews and clear technical documentation.
