Product Engineer

Join a small team building AI-powered voice products for customer service and business operations. You will own product features end to end across agent configuration, integrations, and the systems that support reliable customer interactions.

• Develop and optimize voice agents for speed, reliability, and quality.
• Extend agents to support calls, messaging, and email with shared memory and state.
• Build memory systems that help agents reason across customer workflows.
• Improve observability and tracing so teams can understand and resolve unsuccessful interactions.
• Enable agents to select the most suitable communication channel for each interaction.

Requirements

• At least 3 years of professional software engineering experience, with production experience across frontend and backend development.
• Experience building and owning distributed systems, asynchronous or event-driven workflows, and complex state management in production.
• Production backend experience with Python, FastAPI, or TypeScript, and frontend experience with React or TanStack.
• Experience with real-time audio systems or voice infrastructure, and with LLMs, AI agents, or agentic systems in production.
• Experience with PostgreSQL, Redis, or similar data stores, and cloud infrastructure such as AWS, GCP, or Azure.
