Senior Systems Engineer (Client Computing Platforms)

This is a remote position.

About the Opportunity

On behalf of our international client, Sunbytes is hiring a Remote Senior Systems Engineer (Client Computing Platforms – Application Packaging & Delivery Services) to join their Global IT Infrastructure Services team.

Our client is a global enterprise operating across enterprise, retail, distribution, and manufacturing business segments, running a modern client computing environment that spans Windows and macOS endpoints, iOS and Android mobile devices, and Windows virtual desktops.

In this role, you will be a hands-on subject matter expert in modern client computing and enterprise application packaging and delivery at global scale. You will own the design, standards, packaging, configuration, and ongoing support of all client and mobile application packages, working closely with End User Services, application, information security, and infrastructure teams, as well as vendors and managed service providers.

Key Responsibilities

• Application Packaging & Delivery: Research, engineer, package, and deploy client applications across Windows 10/11, Microsoft 365, macOS, and mobile OS (iOS & Android), integrated with the Microsoft Intune stack, including patching, OS builds/upgrades, release and change management, compliance, and system refreshes.

• Scripting & Automation: Develop solutions using PowerShell, VBScript, Python, JavaScript, and Azure AUM to identify and remediate issues across Windows, macOS, mobile OS, Intune, and M365 Apps. Build automated endpoint health checks and remediation (critical services, failed service restarts, low disk space, high CPU, event log review), and automate client and mobile application updates to reduce manual packaging where possible.
  

• Testing & Quality: Run automated test execution across infrastructure, security, network, systems, applications, hardware, and software to identify bugs and quality issues.
  

• Incident & Change Management: Participate in troubleshooting, incident response, change control, and testing/validation of infrastructure changes across the client computing and distributed environment, including an off-hours on-call rotation.
  

• Vendor & MSP Oversight: Guide contractors and managed service providers performing 24x7 monitoring and alerting, log analysis, approved change execution, OS upgrades, security vulnerability patching, and support ticket resolution.
  

• Architecture, Standards & Strategy: Act as the lead technical resource for client and mobile application packaging and delivery across multiple parallel projects and global IT initiatives. Provide oversight during design, build, test, and operational phases, peer review technical designs against global IT standards, and research and propose new client computing technologies.
  

• Design & Documentation: Participate in cloud and on-prem design sessions, prototypes, and process designs. Maintain architecture standards, SOPs, specifications, technical diagrams, and test scripts.
  

• Stakeholder Communication: Build strong relationships with users, global IT infrastructure, application, and security teams, and external vendors, and provide regular updates to IT management and leadership on projects and initiatives.
