Initial Duration: first contract until the end of year (extension expected afterwards)

Responsibilities
  • Develop scripts and minor customizations for existing ITSM platforms, primarily HaloITSM and Redmine.
  • Support automation and application enhancements using AI-assisted development tools (e.g., GitHub Copilot).
  • Analyze, maintain, and implement changes in undocumented or partially documented legacy applications.
  • Perform partial refactoring of existing systems to improve maintainability and performance.
  • Integrate and consume REST APIs for system interoperability.
  • Work with Python, JSON, and related technologies to implement solutions and automate processes.

Required Skills & Experience
  • Strong hands-on experience with Python development and scripting.
  • Good understanding of REST APIs, web services, and data exchange formats such as JSON.

  • Ability to understand and modify existing codebases with limited or no documentation.
  • Experience supporting legacy applications and performing code refactoring.
  • Familiarity with AI-assisted development tools such as GitHub Copilot is an advantage.
