Quarterhill is seeking a Senior Site Reliability Engineer to support the reliability and performance of smart transportation systems, including a cloud-native tolling platform that processes roadway transactions and payments. The role focuses on ensuring highly available, resilient, and scalable systems through incident response, automation, monitoring, capacity planning, optimization, and disaster recovery.

Responsibilities

• System Reliability: Monitor and maintain the health, availability, and performance of critical transportation services
• Reliability Standards: Define and track service-level objectives (SLOs), error budgets, and reliability metrics for revenue-critical services
• Incident Management: Lead incident response — perform root cause analysis, coordinate resolution across teams, and drive blameless post-incident reviews and follow-up actions
• Automation: Develop and implement automation scripts to streamline operational tasks and improve efficiency
• Monitoring & Performance: Set up and maintain monitoring, logging, tracing, and alerting tools (e.g., Prometheus, Grafana, OpenTelemetry) to track service health, performance, and resource utilization
• Capacity Planning: Help assess and plan for capacity, scaling infrastructure to meet growing transaction volumes — including stateful systems such as distributed SQL databases and event-streaming clusters (e.g., NATS, Kafka)
• Collaboration: Work with software engineering, infrastructure, and operations teams to improve the reliability of systems and services
• System Optimization: Identify performance bottlenecks, troubleshoot issues, and work on optimizations at both infrastructure and application layers
• Continuous Improvement: Contribute to the ongoing improvement of operational processes, documentation, and best practices in the SRE team
• Disaster Recovery: Participate in designing and testing disaster recovery plans to ensure the continuity of critical services

Skills

• 5+ years of experience in Site Reliability Engineering, DevOps, or a similar role, preferably in a mission-critical or large-scale environment, including experience leading incident response and mentoring other engineers
• Experience with cloud platforms (AWS, Azure, GCP) and container orchestration tools (Docker, Kubernetes)
• Proficiency with monitoring and logging tools (Prometheus, Grafana, ELK stack, Datadog, etc.)
• Strong scripting skills in Python, Bash, or Go
• Solid understanding of Linux and Windows administration
• Familiarity with relational databases (MySQL, PostgreSQL, etc.) and distributed systems
• Excellent teamwork and communication skills, with the ability to work across teams to improve service reliability
• Strong troubleshooting skills with a proactive, solution-oriented mindset
• Experience with traffic management systems, sensor data processing, or other intelligent transportation systems
• Knowledge of infrastructure-as-code tools (e.g., Terraform, Ansible, Helm) and GitOps workflows (e.g., Argo CD)
• Exposure to CI/CD pipelines, including pipeline-as-code (e.g., Dagger, GitHub Actions), and Git-based version control

Benefits

• Paid days off ( i. e. vacatio n, sick days, bereavement leave)
