EngineeringBackend Developer

We are seeking a hands-on Senior Backend Engineer to design, develop, and operate reliable backend services and production-grade REST APIs. In this remote role, you will work primarily with Python, FastAPI, and Microsoft Azure, contributing to scalable systems and data-driven products. You will help build and maintain a communications dispatch service that connects messaging queues, external APIs, databases, and data platforms such as Databricks. Working closely with development, data, and IT/DevOps teams, you will contribute to architecture, integrations, and deployment processes. The role offers the opportunity to take ownership of technical solutions in a collaborative, learning-oriented environment focused on clean code, reliability, and continuous improvement.

Design, develop, and evolve backend services and REST APIs using Python and FastAPI, following sound practices for architecture, security, and maintainability.
Build and operate a communications dispatch service integrating messaging queues and external APIs, implementing idempotency, retries, rate limiting, and robust error handling.
Integrate and orchestrate Azure services, relational databases, third-party APIs, and data processes running on platforms such as Databricks.
Design and maintain Azure SQL persistence solutions, including data modeling, migrations, data integrity, and query optimization.
Improve production reliability and observability through monitoring, tracing, automated testing, and failure recovery mechanisms.
Collaborate with development, data, and IT/DevOps teams on technical decisions, integrations, CI/CD pipelines, and deployments across environments.
Maintain clear and useful technical documentation.
