We are looking for a talented
Systems Engineer
who thrives in a fast-paced environment and is excited by the opportunity to be part of the future of air travel. This position is responsible for supporting and maintaining all facets of the infrastructure that delivers our client-facing and internal services.

As a key member of our IT team, you will be the operational backbone of our infrastructure, keeping our server environments healthy and resilient. You will work in a complex, multi-client hosting environment alongside experienced IT staff, with exposure to the security and compliance disciplines specific to our industry. This is a hands-on role with genuine ownership from day one, ideal for someone who wants variety, responsibility, and a direct line of sight to the impact of their work.

• Administer, monitor, and maintain a large Windows Server estate across on-premise virtualized infrastructure and public cloud environments
• Manage day-to-day backup operations: monitoring job health, investigating failures, and verifying recoverability
• Serve as a first line for infrastructure and application monitoring alerts: triage, investigate, resolve, and elevate with clear context
• Support application delivery platforms including remote desktop services, web server farms, and database environments
• Provide responsive internal user support: endpoint troubleshooting, account and access administration, and device lifecycle management
• Execute structured patching and maintenance cycles across servers and endpoints, maintaining compliance reporting
• Manage digital certificate life cycles for client-facing web applications, tracking renewals and coordinating deployments
• Maintain accurate asset inventories, technical documentation, runbooks, and change records
• Develop and maintain scripts to automate recurring operational tasks and reporting
• Contribute to infrastructure projects, environment changes, and continuous improvement initiatives alongside senior team members

• 5+ years of hands-on experience in systems administration, infrastructure operations, or a similar IT operations role
• Strong knowledge of Windows Server administration in a production, multi-server environment
• Practical experience with server virtualization platforms and hypervisor-based infrastructure
• Experience operating enterprise backup solutions, including restore testing and recoverability verification
• Familiarity with infrastructure and application monitoring tools, including alert triage, investigation, and escalation practices
• Working knowledge of directory services, identity management, and endpoint management platforms
• Fundamental networking knowledge: TCP/IP, DNS, DHCP, VLANs, and firewall concepts
• Scripting ability for automation and reporting (Power Shell or similar)
• Strong documentation habits, with comfort producing and maintaining runbooks, change records, and procedures

• Experience in a SaaS, managed services (MSP), or multi-client hosting environment
• Exposure to hyperconverged infrastructure or hybrid cloud environments
• Familiarity with enterprise security tooling such as endpoint detection and response, log analysis, or SIEM/SOC workflows
• Experience with load balancing, reverse proxy, or application delivery technologies
• Understanding of database server administration fundamentals
• Awareness of compliance frameworks such as PCI DSS or ISO 27001 in an operational context
• Relevant certifications:
  Microsoft (Azure/Windows Server), CompTIA (Security+, Network+, Server+), or network and security specific credentials
• Experience contributing to CI/CD pipelines or infrastructure automation initiatives

• Hands-on and independent. You take ownership of problems and see them through without needing constant direction.
• A methodical troubleshooter. You isolate variables, read the logs, and work from evidence rather than guesswork.
• Genuinely curious. You want to understand why systems behave the way they do, not just restore service.
• Organized and consistent. Documentation, change records, and follow-through are habits, not afterthoughts.
• Calm under pressure. Production incidents focus you rather than rattle you.
• Always simplifying. You notice repetition and look for ways to automate or eliminate it.
• Security-minded by default. Least privilege and auditability are part of how you think, not a checklist.
• A clear communicator. You keep the right people informed with the right level of detail.
