Responsibilities 🤓
- Design, develop, and evolve backend services and REST APIs with Python and FastAPI, applying best practices in architecture, security, and maintainability.
- Build and operate the communications dispatch service, integrating message queues and external APIs, with idempotency, retries, rate limiting, and error handling mechanisms.
- Integrate and orchestrate platform components, including Azure services, databases, third-party APIs, and data processes running on platforms such as Databricks.
- Design and maintain persistence solutions in Azure SQL, including data modeling, migrations, data integrity, and query optimization.
- Ensure backend reliability and observability in production by implementing monitoring, tracing, automated testing, and failure recovery mechanisms.
- Collaborate with development, data, and IT/DevOps teams on technical decisions, component integration, CI/CD pipelines, and deployments across environments, maintaining clear technical documentation.
Required Skills 🚀
- 4+ years of experience in backend development, with demonstrable participation in building, integrating, and operating production services.
- Strong command of Python and experience building REST APIs with FastAPI or equivalent frameworks.
- Experience designing modular, maintainable software, applying principles such as SOLID, separation of concerns, and automated testing best practices.
- Experience integrating APIs and distributed systems, including authentication, error handling, timeouts, retries, and resiliency patterns.
- Experience with asynchronous processing and messaging systems, using queues, dead-letter handling, and idempotency (e.g., Azure Service Bus or equivalents).
- Strong SQL and relational database skills, including modeling, querying, migrations, and ORM usage; SQL Server or Azure SQL preferred.
