About the job Backend Engineer, POS & Integrations Backend Engineer, POS & Menu Integrations
About Presto Phoenix, Inc.

Presto is the leading Voice AI company for restaurant drive-thrus, operating at scale in complex, noisy, customer-facing environments. As the AI partner to some of the most iconic restaurant brands in the U.S., Presto is transforming the drive-thru into a revenue engine through AI-driven ordering, personalization, and operational efficiency.

AI is not a feature at Presto, it is the foundation of how we build, evaluate, and evolve our products. We operate with rapid iteration cycles and solve real-world problems where latency, reliability, and accuracy directly impact millions of customer interactions.

This may not be the right fit if you're looking for a traditional 9-to-5 environment. We move at the pace of AI. Roadmaps evolve quickly, and we value builders who thrive in ambiguity, take ownership, and are excited to shape the future of real-world AI systems.

We are looking for a Backend Engineer to help build and scale the core systems that power Presto's Voice AI platform.

This role sits at the heart of our POS & Menu Integration team, where you will design and maintain the backend infrastructure that enables real-time voice ordering. You'll work on ingesting, normalizing, and synchronizing data across a wide range of Point of Sale (POS) systems, ensuring our platform understands menus, availability, pricing, and ordering logic in real time.

Success in this role requires strong backend engineering fundamentals, a systems-thinking mindset, and the ability to build highly reliable, scalable services in a fast-paced environment.

Build and scale backend systems

• Design and develop scalable APIs, services, and data pipelines.
• Build systems that ingest, normalize, and sync POS and menu data across multiple integrations.
• Ensure high availability, reliability, and performance of production systems.

Own system performance and reliability

• Optimize systems for latency, scalability, and uptime.
• Monitor, troubleshoot, and resolve production issues.
• Implement best practices for security and data protection.

Write high-quality, maintainable code

• Write clean, efficient, and well-documented code.
• Develop reusable and testable components with strong emphasis on test coverage.
• Participate in code reviews and contribute to engineering best practices.

Contribute to architecture and infrastructure

• Design backend architectures and make key technical decisions.
• Set up and manage infrastructure for owned services.
• Work with event-driven systems and data synchronization patterns.

Collaborate across teams

• Partner with product, AI, and integration teams to deliver new features.
• Translate real-world restaurant workflows into scalable technical solutions.
• Contribute to technical documentation and system design discussions.

• 4+ years of experience in backend or distributed systems engineering.
• Proficiency in one or more backend languages (Node.js, Python, Java, Go, Ruby).
• Strong experience designing and building RESTful and/or GraphQL APIs.
• Deep understanding of APIs, webhooks, and data synchronization patterns.
• Experience with relational and/or No
  
  SQL databases (PostgreSQL, MySQL, MongoDB) and caching systems (Redis).
• Familiarity with event-driven architectures and message queues (Kafka, RabbitMQ, etc.).
• Experience with cloud platforms (AWS, GCP, Azure) and CI/CD pipelines.
• Strong understanding of system performance, scalability, and reliability.
• Experience with Git and modern development workflows.

• Experience working with restaurant technology, retail systems, or delivery platforms.
• Familiarity with POS systems and menu structures (modifiers, pricing rules, ordering logic).
• Experience contributing to POS integration libraries or SDKs.
• Exposure to voice AI or conversational ordering systems.

We move at the speed of AI. This is a high-ownership environment where engineers have direct impact on real-world systems operating 'll work on technology that is deployed in live customer environments and directly drives business outcomes.
