Role Description 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. - Act as an agent orchestrator using Amazon Kiro: run multiple activities in parallel by leveraging AI agents to accelerate execution, while personally validating results and completing selected tasks manually when needed. - 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. Qualifications - 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 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. Requirements - Escalation on-call rotation. - Occasional travel (quarterly offsites, conferences – less than 10%).
