As aPlatform Engineerat ThinkOn, you'll build and maintain the monitoring, observability, and infrastructure automation that keeps our cloud platform reliable. Your day-to-day will span Zabbix and Prometheus/Grafana for monitoring and dashboards, Opsgenie for alert routing and on-call management, and infrastructure-as-code tooling (Ansible, Terraform, GitLab CI/CD) to deploy and manage it all.

We are looking for qualified candidates who are eager to contribute and grow with us.

You Will:

Monitoring & Observability

• Deploy, configure, and maintain Zabbix for system and network monitoring across the platform.
• Build and maintain Prometheus exporters and Grafana dashboards for capacity planning, performance metrics, and operational visibility.
• Configure and manage Ops genie for alert routing, escalation policies, and on-call schedules.
• Analyze alert noise, tune thresholds, and reduce false positives to keep alerting actionable.
• Integrate monitoring systems with ticketing, communication, and incident management tools.
• Maintain and optimize monitoring infrastructure — database tuning, storage management, high availability.

Infrastructure Automation & CI/CD

• Write and maintain Ansible playbooks for deploying and configuring monitoring infrastructure.
• Use Terraform for provisioning infrastructure resources where applicable.
• Build and maintain GitLab CI/CD pipelines for automated testing, linting, and deployment of monitoring and infrastructure code.
• Follow infrastructure-as-code practices — version-controlled, peer-reviewed, reproducible.
• Act as a first responder for monitoring-related incidents and alerts.
• Investigate and resolve performance issues, outages, or anomalies detected by monitoring systems.
• Escalate to the appropriate teams (network, security, infrastructure) when needed.
• Document incidents, root causes, and resolutions. Contribute to post-incident reviews.
• Provide technical support to internal teams on monitoring tools and dashboards.

Platform Operations

• Work within VMware vCenter / VCF and Kubernetes environments to support monitoring and infrastructure needs.
• Manage notification infrastructure (SMTP relay configuration, delivery troubleshooting).
• Support compliance requirements (ISO 27001, SOC 2) by maintaining audit logging, access controls, and security configurations for monitoring systems.

You Have:

• Diploma or degree in Computer Science, IT, or a related field (or equivalent practical experience).
• Eligible to obtain Secret Level Clearance within your first 3 months of employment. This requires the successful candidate to be a Canadian Citizen and have 10+ years of verifiable police background history.
• Relevant certifications are a plus but not required (e.g., Zabbix Certified Professional, CKA, CompTIA Linux+, ITIL v4 Foundations).
• Hands-on experience with Zabbix(or comparable: Nagios, Icinga,Checkmk).
• Working knowledge of Prometheus and Grafana— writing exporters, building dashboards, PromQL.
• Experience with alert management and on-call tooling(Ops genie, PagerDuty, or similar).
• Comfort with Linux systems administration (this is a Linux-heavy environment).
• Proficiency in scripting and automation— Bash and Python at minimum.
• Experience with at least one IaCtool (Ansible, Terraform).
• Familiarity with CI/CD pipelines(GitLab CI, GitHub Actions, Jenkins, or similar).
• Basic database administration (PostgreSQL or MySQL) for monitoring tool backends.
• Strong diagnostic and troubleshooting skills — you can work through a problem methodically.
• Clear written and verbal communication —you'll document your work and explain technical issues to varied audiences.
• Attention to detail — monitoring generates a lot of data, and you need to separate signal from noise.
• Comfort working independently in a remote environment while collaborating across teams.
• Ability to stay composed during incidents and work under time pressure.

Nice-to-Have

• Experience with Kubernetes operations and troubleshooting.
• Familiarity with VMware vSphere / VCF environments.
