  • Apply full-spectrum technical expertise across architecture design, coding, automated testing, and debugging.
  • Analyze and resolve complex or intermittent bugs while actively participating in validating new features.
  • Promote continuous improvement by staying current with emerging technologies to enhance the existing architecture.
What We Are Looking For
  • Education: Bachelor's degree or university diploma in Computer Science, Software Engineering, or an equivalent technical field.
  • Experience: At least 5 years of professional software development experience.
  • Technical Proficiency: Strong hands-on experience with at least one of the following languages: Go, Python, Node.js, or C#.
