What You'll Be Working On

At Userlike, we’re continuously improving one of Europe’s leading customer messaging platforms — and we’re looking for a Python developer (intermediate to senior) to help us take it to the next level. From intelligent automation to mobile experiences, you’ll play a key role in expanding a mature, stable product with new features, improved performance, and smarter tools.

  • Contribute to the further development of our Django-based backend, with a focus on scalability, maintainability, and performance.
  • Design and implement new features across our unified messaging platform and customer dashboard.
  • Improve and expand AI-driven tools and automation features, some already in use, others built from scratch.
  • Extend and refine the backend for our mobile app, making sure it integrates smoothly with the rest of the platform.
  • Handle transaction management and the deployment of complex APIs that power real-time communication.
  • Work closely with frontend, QA, DevOps, Design, and Product to bring features to life — collaboration is core to how we build.
  • Take part in improving our development processes, suggesting better patterns, tools, or architectural decisions.
