Site Reliability Engineer

We are looking for a Site Reliability Engineer to join our Network and Security Operations Center (NOC), a team at the heart of platform reliability for mission-critical SaaS environments. You will help maintain, optimize, and ensure the reliability and performance of the systems that power our cloud infrastructure across AWS and Kubernetes, with a strong focus on automation, observability, and continuous improvement. This role blends reliability engineering with incident command, giving you real ownership over uptime, performance, and innovation. You will be part of a highly skilled team that values creative problem-solving, operational excellence, and continuous improvement through automation and resilience engineering.

Your responsibilities

• Collaborate with other Engineering teams to support services before they go live through activities such as system design consulting, developing software platforms and frameworks, capacity planning and launch reviews.
• Innovate relentlessly: Identify pain points, propose creative solutions, and drive initiatives that simplify, scale, and strengthen the platform.
• Maintain services once they are live by measuring and monitoring availability, latency and overall system health.
• Own observability: Enhance and expand monitoring and alerting using Datadog; define SLOs/SLIs and create actionable dashboards that drive reliability outcomes.
• Drive automation: Develop and improve internal tooling, IaC frameworks, and pipelines (Terraform, GitLab CI/CD) to reduce manual intervention and enable self-healing systems.
• Scale systems sustainably through automation and evolve systems by pushing for changes that improve reliability and velocity.
• Be on-call.
• Practice sustainable incident response and blameless postmortems. Lead post-incident reviews (RCAs) and identify long-term fixes that improve stability, reliability, and developer experience.
• Implement monitoring, Logging, alerting, and SLA Reporting.
• Create and maintain technical documentation.
• Implement, maintain and mature SRE best practices.
• Lead incidents: Act as Incident Commander for Incidents; coordinate cross-team response, manage communications, and ensure rapid service restoration.
• Provide support for our planning and deployment teams to enable stability, predictability, and scale in our continued growth.
• Collaborate with members of the Platform Engineering team to implement and support far-reaching strategic efforts, provide constructive feedback, and foster a collaborative environment.
• Work cross-functionally with internal teams and vendors to manage our growth around the globe, with a strong focus on maintaining the high level of performance, availability, and reliability for our users.

Requirements

• 5+ years in Site Reliability, Cloud, or DevOps Engineering, ideally in SaaS or large-scale production environments.

• Experience designing and deploying large scale systems, multi-vendor platforms and globally distributed infrastructure.
• Proven experience managing cloud infrastructure in AWS (multi-account, VPC, EC2, EKS) and Kubernetes at scale.
• Strong hands-on experience with IaC and automation (Terraform, Ansible, or similar).
• Familiarity with CI/CD pipelines and release automation (GitLab preferred, Jenkins acceptable).
• Deep understanding of monitoring and observability using Datadog (or equivalent), including metric design, log pipelines, alerting, and dashboards.
• Experience with incident management, on-call participation, escalation, and structured postmortems.
• Scripting skills in Python, Bash, Java or equivalent for automation and diagnostics.
• Curiosity, ownership, and a bias for action; you see a problem, you solve it, and you share the lessons learned.
• Experience with Fedramp (The Federal Risk and Authorization Management Program) compliance is a strong asset.
• Basic knowledge of Java- or .Net-based development required.
• Strong English communication skills, both written and spoken, are essential for effective correspondence with customers, business partners and colleagues beyond the province of Quebec.

Additional requirements:

• Escalation on-call rotation
• Occasional travel (quarterly offsites, conferences – less than 10%)
