Senior Site Reliability Engineer (remote within EMEA)

About the team: Platform Infrastructure builds, operates, and continuously evolves FYUL's container platform and cloud foundation. We foster a DevOps culture through self-service tooling, enabling product engineering teams to ship reliable, secure, and cost-efficient services as the business scales. The team owns our AWS cloud accounts, Kubernetes platform, cloud networking, observability stack, core databases, CI/CD pipelines, and infrastructure-as-code, and acts as the go-to partner for engineering teams on cloud and DevOps topics.

About the role:**

We're hiring a Senior SRE II to join Platform Infrastructure as one of the team's senior individual contributors. At this level, you're the go-to person for our most complex infrastructure problems: you architect and drive large-scale automation and reliability initiatives, set standards other engineers follow, and mentor Associate and mid-level SREs. You'll split your time between hands-on platform work - Kubernetes, AWS, GCP, CI/CD, observability - and technical leadership: proposing designs, reviewing others' work, and helping the team make good build-vs-buy and cost/reliability trade-offs.

Your daily tasks will include:

• Infrastructure & reliability: Architect and manage highly available, secure, and scalable infrastructure across multiple AWS accounts and environments using infrastructure as code.

• Design and operate our Amazon EKS clusters, including networking policies, persistent storage, and scaling strategies for containerized workloads.

• Own and evolve core platform services:cloud networking, Kubernetes, and the databases and messaging systems engineering teams depend on.

• Automation & infrastructure as code: Drive large-scale automation projects and set standards for using Terraform / Terragrunt and GitOps (ArgoCD) across teams.

• Lead adoption of automation to reduce manual operational work and keep environments consistent and repeatable.

• Observability & incident response: Be the go-to person for solving complex, cross-service infrastructure problems.

• Drive initiatives that improve reliability and observability (Grafana, Prometheus, Loki, Tempo, Mimir) so systems scale with minimal manual intervention.

• Participate in on-call rotation, lead incident response for production issues, and write clear runbooks, ADRs, and postmortems.

• Security & cost efficiency: Lead security efforts within the team - IAM, encryption, secure logging - and mentor others on secure infrastructure practices.

• Audit infrastructure spend regularly and drive cost optimization across the platform (rightsizing, autoscaling, FinOps practices).
