Job Description

As a Backend xEngineer, you’ll design and own the core systems that impact millions of users, working with an AI-native focus to craft high-performance backend architectures and scalable, reliable platforms.

In your day-to-day, you will:

• Design and own end-to-end backend systems and features that impact millions of users
• Focus on backend architecture and system design, making thoughtful trade-offs around scalability, reliability, security, and maintainability
• Take full ownership from data models and APIs to production systems and distributed architectures
• Use AI as an integral part of your daily work—for planning, design, execution and production, while ensuring AI-assisted outputs meet the highest production standards
• Work with modern technologies (e.g., Java, Scala, Node.js, Cloud, and CI/CD) while continuously evolving your toolkit with AI-powered tools
• Collaborate closely with product managers, designers, and engineers to shape solutions while ensuring production quality, observability, and long-term system health
  
  

Qualifications

Requirements:

• 4+ years of experience as a software engineer with strong ownership of production systems
• Expertise in at least one core domain (e.g., frontend, backend, mobile) with the ability and motivation to operate across stack boundaries
• Strong software and system design skills, including designing APIs, data flows, and scalable, maintainable architectures
• Experience integrating AI tools into the engineering workflow, with the ability to evaluate, validate, and iterate on AI-generated outputs
• End-to-end curiosity for systems, from product behavior and UX to distributed systems, deployment pipelines, and data stores
• A mindset that values product impact, technical excellence, collaboration, and continuous growth in a fast-evolving, AI-driven environment
