About The Position

We are seeking a Senior Site Reliability Specialist to join our SRE team. Reporting to the Engineering Manager, you are responsible for scaling AWS cloud infrastructure, evolving Kubernetes deployment pipelines, improving monitoring, alerting, and resiliency, and developing tooling that enables product teams to deliver safely and efficiently. For acquired Azure-based products the focus is on monitoring, alert triage, and runbook-driven incident response rather than greenfield platform design. This role owns shared platform services across cloud regions, including databases, messaging, logging, search, and tenant provisioning. The Senior SRE is expected to lead major infrastructure initiatives and proof-of-concept efforts, contribute to technical planning and prioritization, as well as partners with the Product teams to reduce operational incidents. The SRE team also develops and operates AI-driven tools to streamline runbooks, accelerate incident response, and generate operational insights from platform telemetry to improve reliability and reduce manual effort.

Requirements

Bachelor’s or advanced degree in computer science, computer engineering, or related practical fields with demonstrated experience.
5+ years of hands-on experience
Solid hands-on experience with AWS in a multi-account, multi-region environment: EKS, AWS Organizations, IAM, and KMS.
Strong proficiency with Terraform and Infrastructure as Code workflows, including Atlantis/GitOps, state management, and module/provider upgrades.
Practical experience running workloads on Docker and Kubernetes in production, including Gateway API ingress patterns and cluster lifecycle management (upgrades, addons, node provisioning).
Strong experience with Linux systems administration and production troubleshooting.
Proficiency in at least one development or scripting language such as Python, Go, or Bash.
Experience with an observability platform (e.g. New Relic, OpenSearch, CloudWatch, OpenTelemetry) and event-driven alerting (e.g. EventBridge, SNS, PagerDuty).
Knowledge of system and network security fundamentals, including WAF, least-privilege IAM, secrets management, and backup/disaster recovery.
Experience participating in incident management (on-call, triage, remediation, post-incident review) and writing operational runbooks.
Hands-on experience operating Aurora MySQL and PostgreSQL in production, including migrations, performance tuning, and backup/restore.
Strong communication and collaboration skills, with the ability to work effectively across technical and non-technical teams in a distributed environment.

Experience monitoring production systems on Azure is an asset.
Relevant cloud or Kubernetes certifications are an asset.
Bilingual in French and English is an asset

Responsibilities

Design, build, and maintain infrastructure and platform services, including Kubernetes and observability tooling.
Implement infrastructure as code, configuration management, and automated testing to ensure reliable, repeatable environments.
Contribute to code and configuration reviews to improve scalability, maintainability, and reuse.
Monitor production systems, troubleshoot issues, and improve logging, monitoring, alerting, and runbooks.
Participate in on-call and help desk rotations, incident response, and post-incident reviews to improve long-term reliability.
Partner with Product, Engineering, and development teams to translate requirements into reliable and operable infrastructure solutions.
Identify risks across operability, security, performance, and cost, and recommend practical trade-offs.
Contribute to operational quality through runbooks, security hardening, performance tuning, and process improvements.
Stay current with emerging SRE practices, including AI-assisted operations and modern AWS platform patterns.
