About Extendly
Extendly builds mission-critical tools that power thousands of marketing agencies and support hundreds of thousands of end users. Today, we are the backbone of customer experience across the GoHighLevel ecosystem. Tomorrow, we aim to become the core infrastructure through which SaaS companies and modern SMBs manage their data, relationships, and insights—with the help of AI.
We're solving some of the hardest problems in multi-tenant systems, content inheritance, and support-at-scale — all while pushing the limits of what’s possible with generative AI. If you want to work at the edge of AI agents, multi-model orchestration, and deep product extensibility, this is your moment.

Final Note
This is a high-leverage role. You'll help shape the foundation of a platform that will empower not just SaaS platforms, but also the millions of small businesses that need to operate like tech companies — but don’t have the in-house resources to do so.
You’re not just building features. You’re building the infrastructure that helps businesses of all kinds scale.
