Site Reliability Engineer (m/f/d)

About the position As a Site Reliability Engineer in our 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 our engineering teams to ship with confidence - at scale and without compromising availability. This role is perfect for an engineer who is passionate about building high-throughput, highly available systems and who wants to shape how a fast-growing SaaS platform runs in production.

Responsibilities

• Further expand and optimize 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.
• Design and implement zero-downtime deployments, rollback mechanisms and disaster-recovery strategies that keep our platform available around the clock.
• Evolve our LGTM stack (Loki, Grafana, Tempo, Mimir) to give every team the visibility they need - and use it to define and optimize our SLOs.
• Design, develop and optimize infrastructure as code with Pulumi in Go, eliminating toil and making our 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.

Requirements

• 1–3 years of hands-on experience as a Site Reliability Engineer (SRE), 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, since our IaC runs on Pulumi in Go), Python or Kotlin.
• Hands-on experience with infrastructure as code (e.g. Pulumi, OpenTofu, Terraform) and configuration tooling (e.g. Ansible, Chef).
• A collaborative mindset, strong communication skills and business-fluent English.
• Willingness to participate in on-call rotations to ensure the reliability of our platform.

Nice-to-haves

• 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 Kubernetes Operators (e.g. Strimzi, CNPG)
• Experience with operating High-Availability PostgreSQL

Benefits

• Flexibility to work from home
• Occasional team events, workshops, or meetings in our Berlin or Stuttgart offices
• Costs of your E-Gym-Wellpass membership covered
• Job bike leasing
• Regular team events and culture days
• Opportunity to work abroad in the European Union
