Principal Engineer - Go-To-Market

What's the opportunity?

You will be responsible for architecting and delivering a high-scale, AI-native platform that transforms our Go-To-Market operations. By collaborating with data science, infrastructure, and GTM teams, you will execute a "build and buy" strategy to replace our legacy SaaS toolchains and manual heuristics with bespoke AI agents and automated workflows. This role demands a blend of technical leadership and operational rigor, transitioning incubated projects into production-ready solutions while maintaining excellence through robust monitoring, metrics, and support. Ultimately, you will build mission-critical tools that our top GTM operatives rely on to achieve their strategic goals.
