Python Engineer

We’re building a photo marketplace where content must upload fast, be stored reliably, and where integrations and backend processes run smoothly 24/7. We’re looking for a Python Engineer who will own the development and maintenance of our APIs and AWS serverless infrastructure.

About the project

A photo marketplace focused on scalability, performance, and reliability:

• working with large volumes of media (uploading, storage, access, error handling);
• event-driven architecture (scheduled jobs, process automation);
• clear API contracts for the frontend and partner integrations;
• query optimization and high performance for critical user flows.

English: B2 (team communication, technical discussions, documentation).

• Validate and model data with Pydantic, working with schemas and contracts
• Optimize performance (profiling, reducing latency, critical-path optimization)
• Work with AWS: Lambda, S3, API Gateway, EventBridge (including cron/scheduled jobs)
• Design and maintain databases; optimize queries: PostgreSQL and DynamoDB
• Logging, error handling, and improving service reliability (observability best practices)
• Testing (unit/integration) and maintaining code quality
• Participate in code reviews, team collaboration, technical discussions, and architecture improvements

Must-have

• 6+ years of commercial backend development experience
• Python 3.x
• FastAPI, Flask, Pydantic
• AWS: Lambda, S3, API Gateway, EventBridge
