Job Description: Were hiring a Backend Engineer to design and build secure, scalable backend services on Microsoft Azure , with a strong emphasis on data modeling , API development , and serverless compute using Azure Functions . Youll work closely with product and front-end partners to deliver reliable APIs, integrate with Microsoft SQL Server on Microsoft Fabric , and implement robust authentication/authorization and API usage metering/billing . This role is ideal for someone who enjoys building well-structured systems, taking ownership of backend reliability, and applying strong security and engineering practices. The role is outcome-focused: youll be expected to contribute to design discussions and implement robust backend serviceswhile staying open to the best technical approach rather than following a single prescribed pattern. Responsibilities: Key Responsibilities: Data modeling and persistence Design logical and physical data models, schema migrations, indexing strategies, and performance tuning for SQL workloads. Partner with stakeholders to translate requirements into maintainable database structures and data contracts. API design and implementation Build clean, well-documented RESTful APIs (and/or GraphQL where appropriate) with consistent patterns, versioning, and error handling. Implement validation, pagination, filtering, and search-oriented endpoints as needed. Serverless and cloud-native development Develop and operate Azure Functions (HTTP-triggered and event-based) for core backend workloads and integrations. Implement observability (logging, metrics, tracing), resiliency patterns, and cost-aware scaling. Integration with Microsoft data platform Integrate backend services with Microsoft SQL Server deployed on Microsoft Fabric , ensuring reliable connectivity, security, and performance. Work with platform owners to align environments, deployment workflows, and governance. Security: authentication and authorization Implement authentication & authorization using industry best practices (e.g., OAuth2/OIDC, JWT, RBAC/ABAC concepts), aligned with Microsoft identity patterns. Ensure secure secrets management, least-privilege access, and threat-aware API design. API metering and usage-based controls Implement API metering , quota/rate-limiting patterns, usage aggregation, and reporting. Quality, reliability, and delivery Write automated tests (unit/integration), establish CI/CD pipelines, and support releases across environments. Participate in code reviews, define backend standards, and maintain clear technical documentation. Qualifications: Primary language: Strong backend experience with JavaScript/TypeScript (preferred), including production API development. Experience with common frameworks/tooling (e.g., Node.js, Express/Fastify/NestJS) is beneficial. Secondary options: Strong experience with Java or Python backend development (especially for APIs and cloud services). Proven ability to design and build production-grade REST APIs , including: Versioning strategies, input validation, error models, pagination/filtering patterns API documentation using OpenAPI/Swagger Strong fundamentals in relational data modeling and SQL : Schema design, indexes, constraints, transactions, query tuning Hands-on experience building and operating Azure Functions (or equivalent serverless): Deployment, configuration, observability, scaling/cost awareness Experience integrating with Microsoft SQL Server , ideally in a cloud-hosted setup; familiarity with Microsoft Fabric integration is a plus. Strong understanding of authentication & authorization : OAuth2/OIDC, JWT, claims/roles, least privilege, secure secrets management Experience implementing API metering/usage tracking concepts: Rate limiting, quotas, tenant-level usage aggregation, auditability Practical experience with CI/CD , automated testing, and building services that are reliable in production (monitoring, alerting, incident-friendly design). Nice-to-Have Skills: Experience with Azure API Management (APIM) for gateway policies, authentication integration, throttling, and analytics. Familiarity with Microsoft Entra ID (Azure AD) for OAuth2/OIDC flows, app registrations, scopes, and role/claims-based access. Experience using Azure Key Vault for secrets/certificates management and secure configuration practices. Infrastructure-as-Code experience using Bicep and/or Terraform to provision and manage Azure resources in repeatable, audited deployments. .

That number includes positions in India (9,577), Poland (3,429), the United States (1,753), Singapore (787), and Brazil (779). If you're looking to move or work remotely, check which countries match your goals — then filter WorkMundi by location to see what's actually hiring near you.
Most developer ads you'll see are written in English: 18,397 of the 24,795. That doesn't tell you whether the job itself requires you to speak English or work in English daily, so read each posting carefully. Don't assume the language of the ad matches the language of the team.
The employers posting the most developer roles are Link Group (369 jobs), Upvanta (257), jobgether (226), and OfferZen (212). If you're applying to any of these, research their hiring patterns. They move fast and post often, which means they're either scaling hard or replacing people who didn't fit.
In your interview, expect this: 'Walk me through the last time you had to debug something that took you more than an hour. What was it, what did you try first, and what would you do differently?' Hiring managers ask this to see if you think systematically or just try random fixes. Have a real example ready with specifics.
