The employer's own description
ABOUT THE ROLE
This is a high-ownership product engineering role at a seed-stage AI voice platform, where you will build and ship features end-to-end on a small, fast-moving team. You will work across applied AI products, agent configuration experiences, integrations, and the systems that power them, with direct impact on real customer outcomes.
WHAT YOU'LL DO
- Build an AI coworker that configures agents, debugs issues, connects to external systems like CRMs, calendars, and email, and delivers direct answers in place of dashboards.
- Build and optimize voice agents for speed, reliability, and quality at scale.
- Extend agent capabilities to multi-channel interactions including calls, WhatsApp, and email with shared memory and state.
- Develop memory systems that enable agents to reason across entire customer flows.
- Build observability and tracing tooling to make every degraded interaction easy to understand and debug.
- Implement channel-routing logic so agents select the right communication channel for each situation.
WHAT WE'RE LOOKING FOR
- Production experience building and owning product features and the distributed systems behind them.
- Proficiency in Python, FastAPI, and/or TypeScript in backend production environments.
- Experience with real-time audio systems or voice infrastructure.
- Hands-on experience with PostgreSQL, Redis, or similar data stores in production.
- Experience building with LLMs, AI agents, or agentic systems in production.
- Experience building asynchronous or event-driven systems with complex state management.
- Familiarity with cloud infrastructure on AWS, GCP, or Azure.
- Strong software fundamentals across frontend and backend; comfortable picking up unfamiliar domains quickly.
- Bias toward action, strong product sense, and focus on business outcomes over technology for its own sake.
- Nice to have: experience with Temporal or other workflow orchestration tools, multi-channel communication integrations, observability tools such as OpenTelemetry or Honeycomb, or React frontends with TanStack.
