About the Role

As a Founding AI Engineer, you'll lead the development of core AI infrastructure for testing, benchmarking, and monitoring large language model (LLM)-based voice agents. This is a deeply technical role that involves close collaboration with customers and product leadership to ensure agents behave reliably in production environments.

What You'll Do

  • Design and build AI systems for evaluating and stress-testing conversational agents at scale.

  • Create pipelines for benchmarking LLMs and simulating diverse real-world conversational scenarios.

  • Implement real-time monitoring, feedback loops, and alerting mechanisms for deployed agents.

  • Continuously improve system accuracy and performance through experimentation and iteration.

  • Engage with early customers to gather feedback and rapidly improve tooling.

  • Help shape product direction, technical architecture, and team culture.

What We're Looking For

Minimum Requirements:

  • 1+ years of experience building and deploying AI systems in production environments.

  • Proficiency in Python and strong problem-solving ability.

  • A startup mindset: comfortable with ambiguity, fast iterations, and end-to-end ownership.

  • Curiosity and initiative-someone who spots opportunities for improvement and runs with them.

Bonus Points For:

  • Experience at an early-stage startup or in a founding/first-engineer-type role.

  • Background in LLM evaluation, AI benchmarking, or observability tools.

  • Exposure to real-time systems or large-scale conversational agent architectures.

Why Join Us?

  • High ownership: Play a core role in shaping a product, team, and company from the ground up.

  • Technical challenge: Work on complex problems in a space that's still being defined.

  • Tight feedback loop: Collaborate directly with users and decision-makers.

  • Equity upside: Be part of an early-stage company with significant growth potential.

  • Meaningful impact: Help teams deploy more reliable, trustworthy AI.


If you're excited about solving real problems in AI infrastructure and want to work in-person with a lean, driven team building something new - we'd love to hear from you.
