What You'll Do:
- Design, build, and own the systems that power our Voice AI and Text AI agents - handling voice calls, SMS, and email conversations end-to-end across every customer touchpoint.
- Craft system-level prompts that shape agent behavior, reliability, and outcomes, with a deep understanding of how prompt structure translates into real-world performance.
- Develop tool-calling integrations so agents can take reliable, real-world actions - booking appointments, looking up customer data and warm-transferring to humans - safely and predictably.
What It Takes to Succeed:
- Hands-on experience building with LLMs in production - prompt engineering, tool/function calling, evaluation frameworks, or agent orchestration.
- Solid backend experience in one or more of Elixir, Go, Python, or a comparable server-side language, with the curiosity and adaptability to pick up new languages and frameworks as our stack evolves.
- A track record of leading projects from spec to launch alongside multiple contributors.
What You'll Get:
- Full responsibility for projects from day one, a collaborative team, and a dynamic work environment.
