We are looking for a Senior Software Engineer with 5+ years of experience to join a small, high-impact engineering team building AI-powered voice agents that handle millions of calls monthly for Fortune 500 companies.

• Hands-on experience working with LLMs (multi-turn agents, prompt engineering, or tools like LangChain) — not just theoretical knowledge
