Staff Engineer - Client Experience

Technical leadership and mentorship — set a high bar for technical excellence, mentor and coach engineers, and foster a culture of continuous improvement across the team

Architecture and system design — architect and build robust, scalable, and maintainable systems, tackling the deepest technical complexity in the platform

Complex delivery — drive the successful delivery of complex, cross-team projects, making sure they meet business goals and ship on time

Technical vision and strategy — contribute to the technical vision and roadmap, and help define and execute engineering strategy aligned with company goals

Cross-functional collaboration — work closely with product, design, and stakeholders, translating technical concepts clearly for technical and non-technical audiences alike

Quality and performance — optimize performance and scalability through efficient algorithms and clean code, and safeguard quality through rigorous testing and reviews
