Key Responsibilities

What You'll Do

• Design for Resilience: Build and optimize robust backend services capable of handling high-volume traffic while ensuring 100% data consistency and system reliability.
• Evolve Distributed Architectures: Understand the complexities of existing systems and evolve them into scalable, event-driven architectures to meet future global product requirements.

Our Technical Stack

• Backend Core: Node.js (TypeScript), NestJS (or similar frameworks).

• AI & Productivity: GitHub Copilot, Claude Sonnet, ChatGPT, and other GenAI assistants.
• Collaboration: GitHub, GitLab, Slack, JIRA, Notion.
• (Note: You will collaborate closely with our React/React Native teams, but your focus will be 100% Backend).
