You will work closely with frontend and product teams to rebuild backend capabilities including authentication, APIs, storage, and real-time systems in a cloud-native Azure environment.

Key Responsibilities & Skillsets:

• Design, develop, and maintain backend services using Node.js and TypeScript within a Next.js application.
• Lead migration of database systems from Supabase PostgreSQL to Azure Database for PostgreSQL, ensuring data integrity and minimal downtime.
• Replace Supabase auto-generated APIs with custom backend logic using Next.js API routes or Azure Functions.
• Design and implement secure authentication and authorization using Azure Active Directory B2C, including JWT-based session handling and SSR integration.
• Rebuild Row-Level Security (RLS) logic from Supabase into application-layer authorization mechanisms.
• Develop and optimize RESTful APIs and backend services for performance, scalability, and maintainability.
• Integrate and manage file storage solutions using Azure Blob Storage, including secure upload/download workflows.
• Implement real-time features using Azure SignalR Service or alternative event-driven architectures.
• Ensure backend systems follow best practices in security, monitoring, and logging within Azure.
• Collaborate with frontend teams to support SSR and API integrations in Next.js applications.
• Participate in architecture decisions and contribute to cloud infrastructure design and optimization.

Candidate Profile:

• Bachelors or Masters degree in Computer Science, Engineering, or a related field.
• Strong experience in backend development using Node.js and TypeScript.
• Hands-on experience with PostgreSQL, schema design, and query optimization.
• Experience working with or migrating from platforms like Supabase, Firebase, or similar BaaS solutions.
• Practical experience with Azure services, especially:
• Azure PostgreSQL
• Azure Functions / App Services
• Azure AD B2C
• Blob Storage
• Solid understanding of authentication systems, JWTs, and session management (especially SSR contexts).
• Experience designing scalable APIs and handling application-level authorization (replacing RLS).
• Familiarity with modern DevOps practices, CI/CD pipelines, and Git-based workflows.
• Strong problem-solving skills and ability to work in a fast-paced environment.
• Good communication skills and ability to collaborate across teams.
