About the role
Our automotive manufacturing client in the Cambridge, ON area is looking for a well-rounded Infrastructure & Monitoring Engineer to join their Digital Systems & Security team. This is a hands-on operational role with project work mixed in. You’ll be supporting and improving a diverse, integrated technology stack across monitoring, security, and application environments.
This is not a narrow specialist role. The team operates across a broad set of platforms and needs someone who can context-switch, self-manage, and take ownership from start to finish without needing heavy direction. If you thrive in a fast-paced environment where no two days look the same and you like to actually build things—scripts, automations, documentation, solutions—this opportunity is a strong fit.
- Listed city: Toronto, Ontario
- Work location: Cambridge, ON (4 days on-site)
- Contract until March 31, 2027 (strong potential for annual renewal)
- 40 hours per week
- This posting is for an existing vacancy.
- AI may be used in evaluating candidates.
Responsibilities
- Support and maintain the team’s internal monitoring platform (Datadog, Directus, Node-RED) across approximately 1,000 servers and infrastructure components.
- Manage endpoint security across 6,500+ workstations and 1,000 servers using Trellix.
- Coordinate with corporate cybersecurity and local product owners on remediation, controls, and incident response.
- Manage SSL certificates and Zscaler internet filtering across the organization.
- Write Python scripts and automations to improve operational efficiency.
- Create and standardize process documentation and runbooks—a key area of focus for the team.
- Contribute to project work alongside day-to-day operational support.
- Travel occasionally to Woodstock as needed (infrequent).
- Provide after-hours and weekend on-call support (iPhone and laptop provided).
Requirements
Must-have requirements
- Hands-on experience with Datadog for infrastructure and application monitoring (servers, logs, dashboards, alerting).
- Experience with Directus and Node-RED/JavaScript for workflow automation and system integration.
- xMatters for incident response, on-call scheduling, and escalation workflows.
- Python scripting for automation, tooling, and operational support.
- Trellix (or equivalent) for endpoint protection and security policy enforcement.
- Cyber security coordination experience—working with corporate security teams on risk management, controls, and incident response.
- Zscaler for secure web access and zero-trust network security.
- SSL certificate lifecycle management across a multi-product environment.
- Strong project management and time management skills—able to juggle incidents, problems, and project deliverables simultaneously.
- Ability to work independently and manage your own workload with minimal oversight.
Nice-to-have skills
- SAP Basis administration and/or SAP Security (users, roles, authorizations).
- WebSphere, JBoss, or Nginx (WAF/reverse proxy) experience.
- Database experience across Oracle, PostgreSQL/EDB, or SQL Server.
- Power Platform On-Premises Gateway.
- Qualys vulnerability management.
- MongoDB.
- Forescout or similar network access control platforms.
Benefits
- An iPhone and laptop are provided for after-hours and weekend on-call support.
