Senior Sr. Full Stack Engineer II - CX Offering

We seek a highly skilled, motivated Senior Full-Stack Engineer II to join the Customer Experience Offerings (CXO) team. This team delivers and scales our core offerings and agentic experiences, creating smart automation for customers to confidently understand, configure, and optimize their journey.
Part of the Customer Experience group, this high-impact, hands-on role involves working across the full application stack-frontend (React, Next.js), backend (Node.js, TypeScript), data pipelines, and platform development. The ideal candidate has deep expertise in full-stack development, large-scale data stores, event-driven pipelines, data models, and high-throughput infrastructure. As a Senior II, you will be a technical leader: owning complex cross-system initiatives, setting the architectural and quality bar, mentoring peers, and collaborating across teams to drive real customer impact. We're investing heavily in Agentic AI and you'll be a central force in shaping how we build it.
If you thrive on technical ownership, have a track record of setting the quality and architecture bar for a team, and are energized by building experiences that bring real value to customers - we'd love to meet you.
What Youll Be Doing:
Act as the go-to technical expert across one or more core areas of the CXO platform, setting the standard for code quality, maintainability, and architecture for the team.
Drive technical decision-making on complex, mission-critical systems. Lead design reviews for large-scale initiatives and contribute to all major architectural decisions within your domain.
Own and deliver large, cross-system initiatives, handling open-ended problems with ambiguity. Define key success metrics and measure project impact post-delivery.
Proactively identify and drive improvements to system costs, scale, and operational stability.
Proactively engage with customers to understand their needs, document pain points and suggestions, and drive improvements that benefit multiple teams.
Improve team processes: identify gaps in documentation, design/code review practices, and onboarding; propose and lead adoption of improvements.
Think like a product owner: proactively identify opportunities to improve the customer experience from quality-of-life improvements to impactful new capabilities and bring them to the roadmap.
