Luxembourg · Full-time · Mid-Senior
We are looking for a Senior Python Software Engineer to join our agile, product-driven teams and help design, build, and evolve high-quality software solutions.

You will play a key role in delivering production-ready features, shaping technical decisions, and mentoring other engineers while working in a modern, cloud-native environment.

Missions

  • Design, develop, test, and deliver shippable features as part of an agile Scrum team
  • Take ownership of backend services and APIs built with Python frameworks such as FastAPI, Django, or Flask
  • Write clean, maintainable, and well-tested code using object-oriented and modern Python practices
  • Design, optimize, and maintain relational data models using SQLAlchemy (or similar) and Alembic
  • Actively contribute to technical discussions, architectural decisions, and continuous improvement initiatives
  • Coach and mentor junior developers, sharing best practices and fostering engineering excellence
  • Collaborate closely with front-end, DevOps, and product teams to deliver end-to-end solutions

Profile

Must-have Skills & Experience

  • Proven professional experience as a Software Engineer, with strong focus on Python
  • Solid expertise in Python frameworks such as FastAPI, Django, or Flask
  • Experience with Python package management (Poetry, Pipenv, or similar)
  • Strong testing culture with hands-on experience using PyTest and/or unittest
  • Deep understanding of relational databases and SQL, with experience in PostgreSQL, Oracle, or Microsoft SQL Server
  • Experience designing and maintaining schemas using SQLAlchemy and database migrations with Alembic
  • Familiarity with GIT and collaborative development workflows

Nice To Have

  • Experience with data manipulation using Pandas
  • Exposure to front-end frameworks such as Angular or similar

Ways Of Working

  • Team-first mentality with excellent communication skills
  • Comfortable working in English (spoken and written); French is a plus
  • Passion for technology, curiosity, and a good sense of humour — we care about culture as much as code

Our offer

  • Working in a Great Place to Work based in Luxembourg.
  • Attractive salary and pretty cool benefits (meal vouchers, mobile subscription...).
  • Develop your skills and ideas over a coffee, a beer or a pizza during our Neo'vations.
  • Evolve within a strong company culture, you'll join us for the opportunity and you'll stay because we're super cool (well according to 98% of our employees NEOFACTO Annual Survey 2024).
