We handle every inbound call - from orders and reservations to customer questions - ensuring restaurants never miss an opportunity. Our AI agent works 24/7, delivering consistent, exceptional service that helps restaurants grow their business while reducing operational burden.

We’re a seed-stage startup experiencing rapid growth, and we’re building the team that will help us capture significant market demand.

The Role

We're seeking a Backend Engineer with specialization in Agentic Systems to own and evolve the core intelligence of our voice agents. This is a foundational role where you'll architect the conversational flows, optimize performance, and introduce cutting-edge AI capabilities that directly impact thousands of restaurant interactions daily.

This role demands equal excellence in prompt engineering and software development (50/50 split). We need someone with strong engineering fundamentals who can build robust, scalable systems - not just experiment with prompts. You'll be writing production code that handles millions of conversations.

What You'll Do

  • Design and optimize complex agentic workflows - Build sophisticated multi-step conversational flows with dynamic function calling, state management, and context handling
  • Drive prompt engineering excellence - Develop, test, and iterate on prompts that handle the nuanced complexity of restaurant operations
  • Build evaluation frameworks - Create comprehensive testing suites to measure and improve agent performance across diverse scenarios
  • Implement cutting-edge features - Own the development of advanced capabilities including conversation memory, personalization, and context-aware responses
  • Write production-grade code - Develop scalable backend services, APIs, and infrastructure to support our AI agents
  • Stay ahead of the curve - Research and implement the latest LLM techniques, tools, and best practices to maintain our competitive edge
  • Collaborate cross-functionally - Work directly with the engineering team to integrate AI capabilities seamlessly into our product

What We're Looking ForRequired

  • Proven experience with complex agentic systems - You've built production AI agents with multiple tools, functions, and sophisticated state management
  • Deep prompt engineering expertise - Mastery of advanced techniques like few-shot learning, chain-of-thought reasoning, and prompt optimization
  • Strong TypeScript/Node.js proficiency - Ability to implement robust, scalable solutions beyond just prompts
  • Up-to-date AI knowledge - Active engagement with the latest LLM research, tools, and industry developments
  • Systems thinking - Experience with evaluation frameworks, A/B testing, and data-driven optimization
  • Startup mindset - Thrives in ambiguity, moves fast, takes ownership, and is energized by rapid iteration

Preferred

  • Experience with voice AI or conversational systems
  • Familiarity with observability tools like Langfuse
  • Background in restaurant tech or high-volume customer service applications
  • Experience with multiple LLM providers and model selection

Benefits

  • Competitive market salary and meaningful equity stake
  • Health insurance, including vision and dental
  • Unlimited PTO/Sick leave
  • Hybrid office policy (3-4 days in our Austin office)
  • Own the most exciting and dynamic part of our tech stack

We do not sponsor visas or provide relocation assistance.

Important Note

This is a startup environment where we move fast and prioritize results. We’re looking for someone who thrives in ambiguity, takes ownership, and is energized by the pace of early-stage company building. High availability and strong work ethic are essential - this role is perfect for those who want to make a significant impact and grow with a rapidly scaling company.
