Technical Leader overseeing architecture standards and secure cloud deployments at Imagemaker. Responsible for leading backend Java and frontend React development with mentoring duties.
About the role
- Backend Developer designing and building secure backend services on Microsoft Azure. Collaborating on API development, data modeling, and serverless architecture with Azure Functions.
Responsibilities
- 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.
- Build clean, well-documented RESTful APIs (and/or GraphQL where appropriate) with consistent patterns, versioning, and error handling.
- Develop and operate Azure Functions (HTTP-triggered and event-based) for core backend workloads and integrations.
- Integrate backend services with Microsoft SQL Server deployed on Microsoft Fabric, ensuring reliable connectivity, security, and performance.
- Implement authentication & authorization using industry best practices (e.g., OAuth2/OIDC, JWT, RBAC/ABAC concepts), aligned with Microsoft identity patterns.
- Implement API metering, quota/rate-limiting patterns, usage aggregation, and reporting.
- Write automated tests (unit/integration), establish CI/CD pipelines, and support releases across environments.
Requirements
- 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.
- 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).
