WHAT YOU'LL DO

• Design, build, and maintain full-stack features spanning web frontends, mobile apps, backend services, and APIs.
• Develop and consume RESTful and GraphQL APIs, and integrate third-party and internal services (payments, notifications, storage, CDN, auth, analytics, etc.).
• Build and maintain serverless and server-based backend logic, including event-driven processing pipelines and background jobs.

• Hands-on experience with Node.js and at least one other backend runtime or framework (not limited to Node.js alone).

• Experience with cloud platforms (AWS, GCP, or Azure), compute, storage, serverless functions, CDN, and managed databases.
• Practical knowledge of CI/CD, version control (Git), and collaborative development workflows.
• Understanding of application security, authentication/authorization patterns, and data protection best practices.
• Strong debugging and problem-solving skills across the stack, comfortable diagnosing issues from the UI down to infrastructure logs.
• Excellent communication skills and the ability to work independently and take ownership of features end to end.
