ThoughtSpot is disrupting the BI industry with search and AI-driven insights. As we scale our SaaS offering, our core platform must evolve from its foundational roots into a high-performance, hyper-scale, multi-tenant ecosystem.

As a Principal Engineer at ThoughtSpot, you will serve as the technical North Star for large-scale platform modernisation. You will lead the evolution of the core platform into a high-performance, hyper-scale, multi-tenant SaaS ecosystem, driving major architectural migrations and shaping long-term technical strategy.
