Job description

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.
• Working knowledge of 12-Factor App principles and cost optimization / FinOps awareness.
• 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!
