Software Engineer

About the Role

Join a small, fast-moving engineering team at a seed-stage AI voice platform company building the infrastructure that powers thousands of automated customer conversations every day. This is a high-impact, end-to-end ownership role — you'll work directly alongside customers, shape core architecture decisions, and ship meaningful product experiences in an AI-first, communications-enabled environment.

What You'll Do

• Work closely with customers to deeply understand their problems and design product experiences that solve real challenges.

• Build scalable backend infrastructure capable of handling thousands of AI-driven phone calls per day.

• Create intuitive, AI-first user experiences that set a new standard for human–machine interaction.

• Own high-stakes projects end-to-end — from initial concept through production deployment and post-release support.

• Contribute to core architectural decisions that shape the platform's future.

• Experience with scalable async processing or real-time processing systems.

• Hands-on experience building products for AI-first or communications-enabled platforms.
