- Contributing to CI/CD pipelines, DevOps automation and infrastructure-as-code
- Participating in code reviews, technical discussions and continuous improvement initiatives
- Supporting open documentation and transparent version-controlled design choices
- Balancing new feature delivery with the ongoing improvement of existing services
