Senior Site Reliability Engineer

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).

• 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.

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).

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 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).

• Private health insurance.

• 2 extra paid days off to focus on your mental or physical well-being.

• 1 extra paid day off to celebrate a Birthday or any other celebration of your choice.

• Internal and external learning opportunities.

• Access to mentorship, internal meetups, and hackathons, both on-site and online.

• Free and healthy lunch if you work from the Rīga office.

• Design and order your own merch using our platforms with an employee discount.

• Exciting team-building events and parties you’ll never forget!
