Tuyển dụng Senior System Engineer — Managed Service Platform tại Hồ Chí Minh

We are looking for a hands-on Senior System Engineer to lead the technical implementation of the platform supporting our 24/7 monitoring, incident response, and infrastructure operations.

You will turn the proposed architecture into a secure, reliable, documented platform—from tool evaluation and proof of concept through deployment, customer onboarding, and handover to the operations team.

Key responsibilities

• Evaluate and implement the platform. Compare the shortlisted open-source and commercial solutions through practical pilots. Document capabilities, integration effort, operating costs, and limitations; recommend a stack to the Tech Lead and implement the approved solution.
• Build the hosting environment. Configure servers, virtual machines, operating systems, databases, network connectivity, certificates, storage, and supporting services. Maintain separate test and production environments with repeatable deployment procedures.
• Implement infrastructure monitoring. Deploy central monitoring and customer-site collectors. Configure discovery, monitoring templates, dashboards, thresholds, dependencies, maintenance windows, and checks for networks, Windows/Linux servers, virtualization, and agreed cloud services.
• Integrate monitoring with service operations. Build or configure API and webhook integrations so alerts create or update the correct tickets and notify the appropriate engineers. Implement duplicate-event handling, retries, recovery updates, and notification continuity during ticketing outages.
• Implement customer separation and secure access. Configure customer-scoped permissions, SSO/MFA, service accounts, secrets handling, and audit records.
• Automate repeatable work. Develop reviewed scripts and Ansible workflows for installation, configuration, inventory, diagnostics, and approved operational tasks. Use version control, scoped credentials, execution records, and rollback procedures.
• Validate production readiness. Test backups and restoration, supported high availability, collector disconnections, platform failures, capacity, and customer onboarding/offboarding. Track defects and provide evidence against agreed acceptance criteria.
• Prepare operational handover. Deliver deployment documentation, diagrams, runbooks, troubleshooting guides, and onboarding checklists. Train operations staff, mentor the System Intern, and provide technical escalation after launch under an agreed support arrangement.

Yêu cầu ứng viên

• At least 3 years of relevant systems or infrastructure engineering experience, including hands-on implementation of production environments.
• Experience delivering at least one monitoring, infrastructure management, or service-management platform through deployment and operational handover.
• Strong Linux administration and practical Windows Server knowledge.
• Working knowledge of TCP/IP, DNS, routing, firewalls, TLS, virtualization, and cloud infrastructure.
• Practical experience with monitoring configuration, alert tuning, and incident workflows.
• Ability to integrate systems using REST APIs, webhooks, and scripting in Python, PowerShell, or Bash.
• Experience with Git and configuration automation, preferably Ansible.
• Ability to document designs, explain technical tradeoffs, and coordinate implementation with colleagues, customers, and vendors.
• Ability to read and work with English technical documentation.

Preferred experience

• Zabbix or ManageEngine OpManager; iTop, ServiceDesk Plus MSP, or comparable CMDB/ITSM platforms.
• NetBox, paging platforms, secrets management, or privileged-access tooling.
• VMware, Hyper-V, or another virtualization platform; AWS, Azure, or GCP.
• Database administration, container deployment, or infrastructure as code.
• Experience in an MSP, managed hosting, or multi-customer environment.
• Experience with every shortlisted product is not required. We value demonstrated implementation ability and sound engineering judgment.
