The role

• We are looking for a Senior Python Developer (Fullstack, Backend-Heavy) to join one of our high-growth client teams as a core software architect.
• In this role, you will be responsible for designing, scaling, and maintaining high-throughput backend systems while having the fullstack dexterity to build out the corresponding frontends.
• You will handle everything from high-performance asynchronous API design and background task orchestration to state management on the client side.
• This is an ideal role for an engineer who loves the clean syntax and processing capabilities of Python but values the completeness of delivering a seamless end-to-end user experience.
• What we are looking for: 5+ years of production experience with modern Python, with a deep understanding of advanced concepts (metaclasses, generators, decorators) and asynchronous programming (asyncio).
• Mastery of FastAPI for high-performance microservices or Django (including Django REST Framework) for robust, feature-rich monolithic web applications.
• Solid, hands-on experience with modern frontend development using TypeScript and React.js (or Vue.js) to connect backends to reactive interfaces.
• Strong background in handling long-running background tasks and event-driven processing using Celery, Redis, or RabbitMQ.
• Deep knowledge of relational databases (PostgreSQL preferred) including query profiling, optimization, indexing, and object-relational mapping (SQLAlchemy or Django ORM).
• Experience containerizing applications with Docker and deploying services into cloud infrastructure (AWS or Azure) via automated CI/CD pipelines.
• Dedication to writing highly testable code, utilizing pytest for comprehensive unit and integration test coverage.
• Nice-to-have: Familiarity with vector databases (Pinecone, ChromaDB) or integrating LLM workflows.
• Experience with frontend state management libraries (Redux Toolkit, Zustand).
• Knowledge of Infrastructure as Code tools like Terraform.
• Understanding of clean architecture and domain-driven design (DDD)
