Senior Site Reliability Engineer (m/f/d)

As a Senior Site Reliability Engineer in our Platform Squad, you'll own critical reliability domains end-to-end and drive the technical direction within the squad – leading architectural decisions on our platform, mentoring teammates, and continuously raising the reliability bar inside the team.

This role is for an engineer with a proven track record of building and operating high-throughput, highly available systems, who wants senior-level technical ownership and real impact through deep engineering work inside a tight, well-scoped team.

What awaits you with us

• Co-own the architecture: Help drive the architecture and evolution of our cloud infrastructure on Azure and our Kubernetes clusters – designed for high throughput and highest availability – to support Flip's rapid growth across the globe.
• Drive the resilience strategy: Define how we approach global scaling, zero‑downtime deployments, rollback mechanisms and disaster recovery, and make sure the platform stays available around the clock.
• Evolve our observability stack: Improve our LGTM stack (Loki, Grafana, Tempo, Mimir) into a foundation our engineers can trust.
• Improve our IaC Platform: Eliminate toil at the source, and make our infrastructure truly self‑service for engineering teams.
• Lead in incidents: Take a leading role in platform‑related major incidents, drive blameless post‑mortems for the squad, and translate findings into systemic improvements.
• Mentor within the squad: Coach teammates, run RFCs and design reviews inside the team, and help engineers grow into stronger SREs.
• Shape our roadmap: Partner with your squad to define the platform's direction.

What you bring to the table

We're looking for a hands‑on, SaaS‑minded senior Site Reliability Engineer who treats scalability and reliability as a first‑class product concern.

Must‑Have Qualifications

• Proven track record building and operating high‑throughput, highly available systems in production.
• Deep, production‑level experience with Kubernetes on any Hyperscaler.
• Strong experience with modern observability stacks (e.g. Prometheus , Mimir , VictoriaMetrics, Dash0, Loki, ELK) and a clear point of view on SLIs, SLOs and error budgets.
• Solid software development skills in Go (strongly preferred, since our IaC runs on Pulumi in Go) or Python.
• Hands‑on experience with Infrastructure as Code (Pulumi, OpenTofu, Terraform) and GitOps (e.g. ArgoCD) + CI/CD pipeline design .
• Demonstrated ability to lead complex infrastructure initiatives from design to production – including writing RFCs and driving architecture decisions within your team.
• Experience mentoring engineers and raising the technical bar within a team.
• Comfortable owning major incidents end‑to‑end and turning learnings into systemic change.
• Strong communication skills and business‑fluent English.
• Willingness to participate in on‑call rotations to ensure the reliability of our platform.

Nice‑to‑Have Qualifications

• Rolled out production‑ready API‑Gateways with Gateway API (e.g. Envoy Gateway).
• Operated multi‑cluster service meshes (e.g. Cilium, Linkerd, Istio).
• Deployed and maintained Kubernetes Operators (e.g. Strimzi, CNPG).
• Operated highly available PostgreSQL in production.
