This is a high-impact role for engineers who want to move fast, take ownership, and help build a category-defining product from the earliest days. As a Founding Senior Software Engineer, you won't just be shipping features-you'll shape the core systems and experiences that power millions of automated conversations.
You'll work across the stack, solving tough technical challenges in real-time audio, global telephony, and developer tooling. You'll collaborate closely with the founding team, talk to customers, and ship improvements weekly-sometimes daily.
If you're excited by big problems, fast feedback loops, and the opportunity to help define how businesses use voice AI at scale-this is the role for you.
