    Position Overview:

    We’re looking for a curious, impact-driven engineer who is passionate about performance, scalability, and engineering quality.

    • Coach and collaborate
      Review code, share best practices, and help teams build testable, high-quality systems
    • Own problems end-to-end
      Triage issues, perform root cause analysis, and implement long-term solutions—not just fixes
    • Keep knowledge flowing

    • CI/CD and engineering tools (Docker, Jenkins, Git, Jira/XRay)
    • Working across Windows & Linux environments
    • Understand modern software testing and Agile delivery
