Microservice Development: Design and develop high-performance backend services using Python, focusing on scalability, maintainability, and low-latency response times.
API Design & Implementation: Lead the development of gRPC and RESTful APIs, utilizing Protobuf to ensure efficient, type-safe communication between distributed services.
System Integration: Build the "glue" that connects our containerized microservices platform to both modern cloud databases and legacy Windows-based infrastructure.
Backend Optimization: Optimize application performance through efficient concurrency models (AsyncIO), caching strategies, and database query optimization.
DevOps & Deployment: Own the containerization of your services using Docker and Kubernetes, integrating them into robust CI/CD pipelines for automated deployment.
Technical Leadership: Lead code reviews, establish Python coding standards (PEP 8), and mentor mid-level and junior engineers to ensure a high bar for software quality.

This position will be posted for at least 5 calendar days. The posting will remain active until the position is filled, or a qualified pool of candidates is identified.
