Senior Site Reliability Engineer (remote within EMEA)

• A global, inclusive team that’s as supportive as it is ambitious and serious about getting things done • An opportunity to work remotely or in a modern and welcoming office in Riga • Flexible working hours (start your day as late as 11 AM) •

About the team: Platform Infrastructurebuilds, 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). • Collaboration & mentorship: Mentor mid-level SREs, provide detailed feedback, and support onboarding of new team members. • Communicate complex technical concepts clearly to both engineers and non-technical stakeholders. • Partner with product engineering squads to understand their needs and represent Platform Infrastructure in cross-team initiatives. Your qualifications: These reflect the technical bar we hold Senior SRE II's to internally, based on our SRE competency framework and current stack. • Core technical experience: • Solid Linux systems administration background and comfort scripting in Python. • Strong AWS knowledge: EKS, IAM (roles, policies, IRSA), VPC networking, RDS, S3, SQS, and familiarity with the Well-Architected Framework; experience in multi-account AWS environments is a strong plus. • Hands-on experience operating and troubleshooting Kubernetes (EKS) at production scale, including Helm chart development, CNI networking (we run Cilium), pod networking/IPAM concepts, and container security (ECR, image scanning). • Proficiency with Terraform (modules, state management) and ideally Terragrunt for multi-environment management; GitOps experience with ArgoCD. • Experience with Postgres, MySQL and/or MongoDB in production scale, including Aurora. • CI/CD experience with Jenkins (Jenkinsfile, shared libraries) and/or GitHub Actions, and familiarity with deployment strategies such as blue-green and canary. • Experience with the Grafana observability stack (Grafana, Prometheus, Loki, Tempo, Mimir) - metrics design, dashboarding, alerting, log aggregation, and distributed tracing. Not only using but also maintaining it. • Practical incident management experience: on-call rotations, structured incident response, and writing runbooks/postmortems. • Working knowledge of 12-Factor App principles and cost optimization / FinOps awareness. 2.How you work: • A methodical, data-driven approach to troubleshooting rather than guessing. • Strong written communication - you write runbooks, ADRs, and postmortems that others can actually follow. • Comfortable driving initiatives with ambiguous ownership, and taking accountability for outcomes rather than waiting to be asked. • Track record of mentoring less senior engineers and giving direct, constructive feedback. • Several years of hands-on production infrastructure/SRE experience, with demonstrated ownership of initiatives at a senior individual-contributor level (leading design work, setting standards, being the escalation point for hard problems). 3. Nice to have: • GCP Experience. • Experience with Kafka / AWS MSK. • Prior experience in regulated or compliance-sensitive environments (security best practices, access reviews). • Experience contributing to a platform/DevEx roadmap that other engineering teams consume as a self-service product. Our tech stack: • Languages:PHP (Symfony), Node.js (TypeScript), Angular (TypeScript). • Data:PostgreSQL, Redis, MongoDB. • Infra: AWS, Kubernetes, Terraform, Helm, Atlantis • Engineering Tools:Postman, Git, GitHub Copilot, PhpStorm, Grafana, Kibana, Prometheus. • Remote work Tools:Jira, Miro, Google Workspace, Slack. • Development Practices:Pair Programming, Code Reviews, Continuous Integration/Deployment. What we offer: • A global, inclusive team that’s as supportive as i
