We are looking for a Python Software Backend Engineer to build the backends and APIs behind our solutions: services that consume and publish events, store and serve data, and integrate with our clients' systems in real time.
We are not looking for someone who just resolves tickets.
We want someone who talks to the client, understands the business problem behind each request, and converts it into code that works in production.
In addition to this, it is important to have AI integrated into your daily way of working, not just as something you test from time to time.
100% of the team at GALEO uses Python on a daily basis.
If you like writing clean code and understanding the purpose of what you build, you will fit right in here.
What you will do day-to-day Python backend and API development (Fast API or similar), with modular, tested, and easy-to-maintain code.
Data model design and working with relational and No SQL databases, mainly Postgre SQL and Dynamo DB.
Development of services that produce and consume events on Kafka or other pub/sub systems.




Deployment and operation of these services in AWS alongside the rest of the team.
Client meetings to gather requirements, turn them into concrete features, and propose how to solve them.
Use of AI tools throughout the entire cycle: design, development, testing, code review, and documentation.
Key Requirements 3+ years developing backend with Python.
Experience designing and building REST APIs.
Strong SQL skills and experience with Postgre SQL.
Knowledge of Dynamo DB or other No SQL databases, and understanding when it makes sense to use each one.
Basic knowledge of AWS, especially its database services (RDS/Aurora, Dynamo DB).
You don't need to be a cloud expert.
Experience with Kafka or other pub/sub tools (SNS/SQS, Rabbit MQ, MQTT...) and event-driven architectures.
You use AI tools daily for development (Claude Code, Cursor, Kiro, Codex, or similar) and critically review what they generate.
You feel comfortable speaking
