The vision is ambitious: replace a significant portion of today's fragmented SaaS stack with a single AI-powered teammate capable of completing real business tasks autonomously.

As the company scales rapidly, they are seeking exceptional engineers to help build the core infrastructure powering the next generation of AI agents.
