• Ship well-scoped backend features and fixes in our Spring Boot + Hibernate stack, using AI to speed up delivery
• Join architecture and design discussions, ask questions, and contribute ideas
• Build working relationships with peers across Mobile, Embedded, and Product
• Learn the end-to-end flow of the backend areas you work in, including how they interact with the app and device firmware
• Be the main driver for medium-sized features, from design through deployment
• Own a component within a core area such as IoT device communication, registration/auth flows, device routine scheduling, or backend support for mobile app features
• Troubleshoot and fix production issues in your areas, and escalate early when a problem is bigger than it looks
• Add or improve monitoring and alerting using Graphite, ELK, or other internal tools
• Own a backend area and handle most questions and issues in it without escalating
• Lead the design and delivery of a large project, with guidance from senior engineers
• Find and make improvements to reliability, test coverage, and developer experience
• Help onboard new teammates, and pass on what you've learned through code reviews and documentation

• Experience building and maintaining RESTful JSON APIs in production
• Distributed Systems, JVM languages, Python, AWS, MySQL, Infra and Monitoring Tools (Ansible, Jenkins, ELK. Graphite, Docker, etc.)
• You know how to write automated tests and can explain how and where to use them (and not)
• You believe in Continuous Deployment and understand testing's crucial role
• You write code that is simple, readable, and easy to maintain
• You notice when you're going down a rabbit hole and know when to raise concerns
• Asking for help is a strength, not a weakness
• You dive into new tech and paradigms that are unfamiliar and uncomfortable with eager glee
• You've picked up multiple languages over your career and stay curious about new tools, frameworks, and technologies
• You make everyone around you better
