Python Developer

Job Description

Responsibilities:

• Design, build, and maintain scalable REST APIs and backend architectures using Flask, ensuring clean separation of concerns and modular blueprints.
• Audit and optimize database queries, request-response lifecycles, and caching policies to ensure low latency and continuous platform uptime.
• Integrate third-party APIs, payment gateways, and internal microservices using secure webhooks and message queues.
• Maintain high test coverage using pytest, perform code reviews, and implement strict security protocols for user authentication and authorization.
• Collaborate with infrastructure teams to containerize applications, manage environment configurations, and streamline deployment workflows.

What we’re looking for:

• 3+ years of hands-on production experience building, securing, and scaling web applications using Flask and modern Python (3.10+). Deep understanding of WSGI/ASGI servers (Gunicorn, uWSGI), Flask application factories, blueprints, and context managers.
•  5+ years of software engineering experience building enterprise backend systems, design patterns, and RESTful web services.
• Expert knowledge of relational databases (PostgreSQL, MySQL), proficient in schema design, query optimization, and leveraging SQLAlchemy with Alembic for migrations. Redis experience for session management and caching.
• Solid experience handling asynchronous tasks, background jobs, and scheduled processes using Celery alongside brokers like Redis or RabbitMQ.
• Daily experience using Docker, container management, and integrating code into automated CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins).
• Strong grounding in web security best practices (OWASP Top 10, JWT, OAuth2, CORS handling) and automated testing frameworks (pytest).
• Located in the CET timezone (+/- 3 hours), we are unable to consider applications from candidates in other time zones.

Nice-to-Have

• Experience decomposing Flask monoliths into modern asynchronous microservices (FastAPI/Go).
• Experience with frontend integration (React, Vue, or Jinja2 templating for legacy apps).
• Familiarity with cloud platforms (AWS, GCP, or Azure) and serverless infrastructure (AWS Lambda, Zappa).
