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.
