About the job

 Are you a vibe coder with a passion for development, and do you believe AI will redefine your profession?

Welcome to SFEIR.

What We Are Looking For

You are unafraid to:

- Design large-scale distributed systems using Python,
- Lead the overhaul of complex Cloud infrastructures,
- Build robust and efficient data pipelines,
- Mentor junior developers and share your expertise,
- Migrate technologies (Flask → FastAPI, protobuf → Pydantic) without disrupting production,
- Propose architectural improvements through Proof of Concepts,

You aim to be the technical reference that drives projects forward, not just a task executor.

Projects You Could Enjoy

- Create complex REST APIs using FastAPI in distributed architectures,
- Automate content translation with Google Cloud Generative AI,
- Build Jupyter Notebooks for data ingestion and processing,
- Establish documentation bases and ensure team onboarding,
- Validate ML results with the Natural Language API and generate reports.

In short, Python on impactful projects that matter to the business.
