Job description

Within Wonder, the Robotics team (Spyce) is a core pillar of our innovation strategy. We build the automation solutions that help make Wonder’s 'no-compromise' promise possible at scale. Our mission is to use robotics to enable incredible variety and culinary authenticity. By reimagining the kitchen environment, we improve the daily experience of our team members and ensure every customer receives a perfect meal, every time.

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.

As a matter of company policy, Wonder does not sponsor applicants for employment visa status for this role.

This role is based in our Boston office in Charlestown, MA. Our hybrid model requires 3 days a week in the office. That said, many team members choose to come in more often to take advantage of in-person collaboration and connection. You're welcome—and encouraged—to be in the office up to 5 days a week if it works for you.

Massachusetts: $139,500 - $151,000 per year.

Wonder uses geographic-specific salary structures, which means the salary offered may vary depending on where the job is located. The final salary offer will take into account various factors, such as the candidate's skills, education, training, credentials, and experience.

Benefits

The benefits applicable to this role include a competitive compensation package with equity and a 401(k). We also offer a choice of medical, dental, and vision plans, company paid short and long term disability coverage, paid time off including flexible time off for exempt employees, paid vacation for non-exempt employees, and paid sick leave in compliance with applicable law in addition to paid parental leave, discounted meals and exclusive perks across the Wonder family of brands.
