What You’ll Do: Use AI-assisted development tools, including Claude Code, to accelerate implementation while validating correctness, security, and performance. Design and build server-side APIs that authenticate users, accept and manage backups, handle large-scale data operations, and prepare restored data for customers across our global user base. Collaborate with Product, QA, and Support teams to ensure both backend features reflect real customer workflows and usage patterns. Build and maintain support tooling to help diagnose and resolve customer issues at scale. Ensure all code and open source assets meet high standards for testing, documentation, reproducibility, and developer usability.
