About HFM:
HFM is an internationally acclaimed multi-asset broker, delivering cutting-edge trading tools, platforms, and conditions to traders worldwide. We are committed to innovation, transparency, and excellence in the financial markets.

Your Role at HFM:

As a Senior Windows Core DevOps Engineer, you will lead the design, automation, and operations of core infrastructure services built around the Microsoft ecosystem. This is a senior-level engineering role focused on modernizing Windows-based systems, introducing infrastructure as code across Windows workloads, and ensuring scalable, secure, and resilient infrastructure across our stack.

You will:

  • Architect and automate core Windows infrastructure (AD, DNS, DHCP, Group Policy, IIS, Windows Clustering, etc.) in a high-availability trading environment.
  • Lead projects to refactor and modernize legacy Windows-based systems, transitioning them into fully automated, testable, and observable components.
  • Drive adoption of Infrastructure-as-Code and CI/CD workflows using modern Microsoft-native and cross-platform tooling.
  • Troubleshoot and optimize system performance at the OS, networking, and application level across a large fleet of Windows servers.
  • Define and implement secure baselines, monitoring, patching, and compliance across Windows infrastructure.
  • Build PowerShell modules, DSC configurations, and leverage tools like Ansible, SaltStack, or Terraform with Windows providers to unify automation.
  • Act as the highest escalation point for Windows-related production issues.
  • Partner with other Core DevOps, Security, SRE, and Cloud teams to standardize and scale our Windows platform.
  • Mentor engineers across teams and promote best practices in observability, resilience, and automation-first thinking.

Requirements

  • 8+ years of experience with enterprise-level Windows Server engineering and DevOps practices.
  • Deep expertise with DNS, DFS, IIS, and Windows Failover Clustering.
  • Solid experience with automation and configuration management using PowerShell (advanced scripting), Desired State Configuration (DSC), and/or Ansible/SaltStack for Windows.
  • Strong understanding of CI/CD concepts applied to Windows environments using GitLab, Azure DevOps, or similar tools.
  • Hands-on experience integrating Windows infrastructure with hybrid or cloud-native solutions (preferably AWS).
  • Experience with infrastructure provisioning tools like Terraform (including Windows modules) or CDK.
  • Strong grasp of Windows performance tuning, debugging, event log analysis, and patching strategy at scale.
  • Background in regulated or high-uptime environments such as banking, Forex, or fintech is highly preferred.
  • Familiarity with SQL Server automation, .NET Core deployments, and Windows Containers is a plus.
  • Comfortable leading incident response and system-level post-mortems for Windows-based production outages.

Benefits
By joining us, you can expect:

  • Hybrid Work Model (2 days working from home).
  • 22 days of Annual Leave (reaching up to 30 days per year based on years' service)
  • Comprehensive Health & Life Insurance (from day one)
  • Friday afternoons off in Summer (July & August)
  • Birthday Leave
  • Gym Membership (Larnaca)
  • Referral Bonus
  • Paid Time Off for Training & Education
