• Tools and AI: Experience with IDEs such as Cursor or Windsurf, proficiency in utilizing Copilots, and the application of advanced AI features to enhance delivery are regarded as significant advantages.

The person who matches our culture is:

• A proactive problem-solver with strong analytical skills and a results-oriented mindset.
• A collaborative leader who fosters teamwork and encourages employee development.
• A skilled communicator who can negotiate effectively and bridge communication gaps between teams.
• Creative and innovative thinker, open to new ideas and continuous improvement.
