About the Project

The project is an online platform designed to systematize and manage a comprehensive range of therapies, supporting complex domain logic and long-term product evolution.
The backend is built on a legacy Django-based framework, requiring a senior-level engineer capable of understanding, maintaining, and gradually improving an existing system.

This role is for a highly autonomous Senior Python Developer who will be the sole developer on the project, fully owning the technical direction, daily execution, and system evolution.

 Key Responsibilities:

• Take full ownership of the backend system built with Django.
• Translate business requirements into technical solutions and execution plans.
• Maintain and evolve a legacy codebase, improving stability, performance, and maintainability over time.
• Design and implement new features using PostgreSQL, Celery, Redis, and Elasticsearch.
• Proactively identify technical debt and propose pragmatic improvement strategies.
• Use AI tools to improve development efficiency, debugging, and refactoring where appropriate.
• Ensure system reliability, scalability, and long-term sustainability.
   

What We’re Looking For:

• 6+ years of professional experience as a Python Developer.
• Strong hands-on experience with Django in production environments.
• Solid knowledge of PostgreSQL, relational data modeling, and query optimization.
• Experience with asynchronous/background processing using Celery and Redis.
• Practical experience with Elasticsearch or similar search technologies.
• Proven ability to work independently and autonomously as the sole developer on a project.
• Strong business-to-technology translation skills — ability to understand business goals and implement them technically.
• Proactive problem solver who takes ownership and responsibility for outcomes.
   

 Ideal Mindset:

• Ownership & Responsibility: You treat the system as “your product.”
• Creative Contributor: You suggest better approaches, not just implement tasks.
• Efficiency through AI: You actively use AI tools to speed up development and problem-solving.
• Passion & Engagement: You care about the product, its users, and its long-term success.
