Site Reliability Engineer

About the role

As a Site Reliability Engineer in the Platform Squad, you will be a key player in keeping Flip's infrastructure fast, resilient and ready to scale. You'll shape the reliability culture, tooling and practices that allow engineering teams to ship with confidence - at scale and without compromising availability.

What you'll do

• Further expand and optimize cloud infrastructure on Azure and Kubernetes clusters designed for high throughput and highest availability to support Flip's rapid growth across the globe.
• Design and implement zero-downtime deployments, rollback mechanisms and disaster-recovery strategies that keep the platform available around the clock.
• Evolve the LGTM stack (Loki, Grafana, Tempo, Mimir) to give every team the visibility they need and use it to define and optimize SLOs.
• Design, develop and optimize infrastructure as code with Pulumi in Go, eliminating toil and making the platform self-service for engineering teams.
• Promote CI/CD best practices, incident management, post-mortems and developer experience across the entire engineering organization.
• Collaborate with your squad and engineering leadership to define the platform's direction - from scalable, high-throughput systems and cost optimization to security posture and compliance.

What you'll need

• 1–3 years of hands-on experience as a Site Reliability Engineer, Platform Engineer, DevOps Engineer, Infrastructure Engineer, Cloud Engineer, or Backend Engineer with a strong infrastructure focus.
• Experience operating and scaling cloud infrastructures (Azure, GCP, AWS).
• Deep knowledge of Kubernetes and container orchestration in production environments.
• Hands-on experience with modern observability stacks (e.g. Prometheus, Mimir, Loki, ELK) and comfortable defining and operating SLOs and error budgets.
• Solid software development skills in Go (preferred), Python or Kotlin.
• Hands-on experience with infrastructure as code (e.g. Pulumi, OpenTofu, Terraform) and configuration tooling (e.g. Ansible, Chef).
• Collaborative mindset, strong communication skills and business-fluent English.
• Willingness to participate in on-call rotations to ensure the reliability of the platform.

Nice to have

• Experience building and operating high-throughput, highly available systems in production.
• Experience with Azure Kubernetes Service (AKS) specifically.
• Experience with Kubernetes Gateway API and Envoy Gateway.
• Familiarity with GitOps workflows and CI/CD pipeline design.
• Knowledge of service mesh technologies (e.g. Linkerd, Istio).
• Experience with operating High-Availability PostgreSQL.
