    About the Role

    We’re looking for Senior / Principal DevOps Engineers to support Orbis, a large legacy platform built on bespoke, business-critical systems.

    Must-Have Requirements

    • Strong .NET / C# development skills to understand large volumes of legacy custom code
    • Solid experience with older Microsoft enterprise environments:
    • Windows Server administration
    • SQL Server
    • .NET / ASP.NET / C#
    • A blended background across DevOps, Windows infrastructure, and .NET engineering
    • Comfortable working with minimal documentation and creating it from scratch

       

    Tech Stack

    • Microsoft Windows Server
    • MS SQL Server
    • .NET / ASP.NET / C#
    • Terraform
    • Jenkins
    • CI/CD pipelines, Docker, Git
    • AWS (nice to have)

       

    Soft Skills

    • Strong problem-solving and analytical skills
    • Ownership mindset and high attention to detail
    • Clear and proactive communication
    • Ability to manage multiple priorities in a fast-moving environment
    • Comfortable working independently and leading discovery efforts

       

    Team & Time Zone

    The core application team is based in Brussels and Paris, with broader collaboration across global teams. This role requires EU-based engineers to align with European working hours.
