IT Infrastructure Technician

About PosiTrace

PosiTrace is a fleet management technology company processing real-time GPS telemetry and video data from thousands of devices across North America. Our platform tracks vehicles, monitors driver behavior, and provides analytics for fleet operators — handling millions of data points daily through a distributed cloud architecture.

The Role

You'll work directly under our Senior DevOps & Infrastructure Engineer, learning to maintain and improve the cloud infrastructure that powers our fleet tracking platform. This is a hands-on role where you'll grow from executing guided tasks to independently managing production systems.

What You'll Do

Infrastructure & Cloud Operations

• Manage and monitor GCP resources: GKE clusters, Cloud SQL instances, GCS buckets, Compute Engine VMs
• Maintain Docker containers and Kubernetes deployments across staging and production environments
• Monitor system health using Zabbix, GrayLog, Google Cloud Monitoring, and internal tools
• Manage VPN access, SSL certificates, DNS records, and firewall rules
• Participate in on-call rotation for infrastructure incidents (after ramp-up period)

CI/CD & Deployment

• Assist with BitBucket Pipelines for automated builds, tests, and deployments
• Execute deployments following established workflows with git tag versioning
• Support rollback procedures and hotfix workflows when production issues arise
• Containerize services with Docker/Helm and deploy to GKE

IoT Device Infrastructure

• Monitor and maintain backend services that handle communication with GPS trackers and cameras in the field
• Track service health and data flow through the processing pipeline — from device ingestion through message queues to storage
• Assist with troubleshooting device connectivity issues: validate network settings, check SIM card status across cellular providers, verify configurations
• Support ongoing containerization and migration of services to Kubernetes

Data Pipeline & Storage

• Monitor message queue health, backlog, and consumer lag
• Support Elasticsearch, Redis, and MongoDB operations
• Assist with MySQL database maintenance and troubleshooting

What You Bring

Required:

• Basic understanding of Linux system administration (Ubuntu/Debian)
• Familiarity with Docker containers and basic Kubernetes concepts
• Exposure to at least one cloud platform (GCP preferred, AWS or Azure acceptable)
• Understanding of networking fundamentals: TCP/IP, DNS, firewalls, VPN, SSL/TLS
• Basic scripting skills in Bash; Python or Go a bonus
• Familiarity with Git version control and CI/CD concepts
• Strong troubleshooting mindset
• Willingness to learn IoT device management and fleet technology

Nice to Have

• Experience with CI/CD tools (BitBucket Pipelines, GitHub Actions, or similar)
• Exposure to monitoring tools (Zabbix, Grafana, GrayLog, or similar)
• Familiarity with message queues (RabbitMQ, Kafka)
• Knowledge of MySQL administration basics
• Any exposure to IoT devices, embedded systems, or telemetry data
• CompTIA, GCP, or Kubernetes certifications (or studying for them)

Why PosiTrace

• Real-world infrastructure: Production Kubernetes, distributed systems, real-time data pipelines
• IoT + Cloud: Unique combination of hardware device management and cloud infrastructure
• Direct mentorship: Work 1:1 with a senior engineer who built and runs the entire infrastructure
• Impact from day one: Small team means your work matters
• Growth path: Clear progression to DevOps Engineer as you take on more responsibility
