Job Description

We’re 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 You’ll 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: you’ll be expected to contribute to design discussions and implement robust backend services—while staying open to the best technical approach rather than following a single prescribed pattern.

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.

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.
