Senior Software Engineer – VoIP

We're building the tools that help local businesses connect, grow, and win. We're looking for a Senior Software Engineer who thinks like a product owner, someone who's scrappy, opinionated, and energized by taking something from zero to one, with expertise in building VoIP solutions. In this role, you will join a team of intelligent and dedicated engineers tasked with empowering local businesses by creating a modern phone service for collecting and converting leads for local businesses through AI agents. You care more about what ships than what stack you're shipping on, and you use AI tooling (Claude Code, Codex, Cursor) as a genuine force multiplier, not a novelty.
