    We are looking for an experienced Senior Python Developer to join and strengthen our growing team. You’ll work on backend systems that power scalable, high-performance applications — including those with AI components. 
     

    What you'll do:

    -Design and develop reliable, maintainable, and scalable backend systems in Python.

    -Drive the architecture of new features and systems, making key technical decisions.

    -Lead integration of AI components (e.g., LLMs, LangChain, vector databases).
    -Collaborate across teams to deliver solutions that meet client needs.

    -Ensure code quality through testing, code reviews, and best engineering practices.

    -Participate in DevOps processes (CI/CD, monitoring, cloud deployment).

    -Mentor and support mid-level and junior developers.
     

    Requirements:

    -Strong proficiency in Python and backend system design.

    -Excellent spoken and written English communication skills.

    -Solid experience with asynchronous programming (e.g., asyncio, FastAPI, aiohttp).

    -Deep knowledge of relational databases (PostgreSQL, MySQL) and ORMs (SQLAlchemy, Django ORM).

    -Practical experience with CI/CD pipelines, containerization (Docker), and cloud deployment.

    -Strong understanding of software engineering principles, version control (Git), and testing frameworks (e.g., pytest).
     

    Nice to have (not mandatory, but a big plus):

    -Experience with LLMs, LangChain, vector stores (e.g., FAISS, Weaviate).

    -Background in Data Science or Machine Learning.

    -Experience with Cloud Infrastructure (AWS, GCP, Azure).

    -Familiarity with microservice architectures and distributed systems.
    -Previous experience in client-facing roles or product-focused development.
