About The Opportunity

The Infinite Kitchen is the heart of Wonder's automation future. We are looking for a Software Engineer to join our backend team to build and maintain the "brains" of our automated restaurants. In this role, you will focus on the mission-critical applications that orchestrate the lifecycle of a customer order and systems that manage a fleet of connected robotic systems across the country.

You will work primarily with Elixir and the Phoenix framework to build real-time distributed systems that bridge the gap between our cloud infrastructure and on-premise robotics. You will collaborate closely with frontend, robotics, and QA engineers to ship features that directly impact how we feed thousands of customers.

The Impact You Will Make

• Orchestrate the Kitchen: Develop the Elixir applications that manage order processing, store pacing algorithms, and real-time event handling.

• Produce High Quality Software: We are proud of the phenomenal uptime we have on our Infinite Kitchens. The ideal candidate for this role will champion reliability on the Infinite Kitchen product line.

• Bridge Cloud and Hardware: Build and maintain robust APIs and WebSocket protocols to communicate between cloud event streams and on-site Python-based robotics applications.

• Data Integrity & Performance: Manage and optimize Postgres databases to ensure every order is tracked accurately and processed with minimal latency.

• Feature Innovation: Design and implement complex business logic, including order prioritization, B2B features, and store-level resource management.

• Operational Excellence: Participate in the on-call rotation, a standard responsibility for all Infinite Kitchen engineering roles.

What You Bring to the Table

• 2+ years of professional software development experience.

• Proficiency in Elixir and the Phoenix framework (or significant experience in other functional languages with a desire to master Elixir).

• Experience with PostgreSQL and database design.

• Strong understanding of real-time communication (WebSockets, Phoenix Channels) and event-driven architecture.

• Familiarity with building and consuming RESTful and/or GraphQL APIs.

• A pragmatic approach to problem-solving and a passion for building reliable, real-world systems.
