Senior Site Reliability Engineer (f/m/x)

We are seeking a Senior Site Reliability Engineer to drive reliability, scalability, and operability for our customer-facing platforms. You will design and automate resilient infrastructure, evolve observability and incident response, and partner with product and platform teams to embed SRE principles-availability, latency, performance, efficiency, change management, monitoring, emergency response, and capacity planning-into day-to-day engineering.. Sounds like you? We are looking forward to your CV!

Your Tasks

• Reliability by Design: Define and evolve SLOs/SLIs and error budgets for critical services; implement guardrails that balance feature velocity with reliability.
• Observability: Lead end-to-end monitoring, logging, and tracing-build actionable dashboards and alerting hygiene (noise reduction, clear ownership, self-healing runbooks).
• Production Engineering: Own incident management lifecycle (triage, escalation, comms, blameless postmortems), drive corrective actions, and track reliability risks to closure.
• Automation & Tooling: Build and maintain Infrastructure as Code (IaC), GitOps workflows, and release/rollback automation to reduce toil and change risk.
• Performance & Capacity: Conduct load testing, capacity modeling, and cost/performance tuning; forecast growth and right-size infrastructure.
• Security & Compliance: Partner with Security to embed secrets management, least-privilege, patching, and policy-as-code into the platform.
• Platform Stewardship: Improve developer experience-golden paths, paved-road templates, CI/CD guardrails, and reliable dev/test environments.
• Cross-Team Collaboration: Coach squads on SRE best practices; influence architecture for reliability (back-pressure, bulkheads, retries, circuit breakers, idempotency).
• On-Call Excellence: Participate in and mature on-call rotations; continuously improve MTTA/MTTR with automation, better runbooks, and robust failure testing.
• Continuous Improvement: Instrument reliability KPIs; run chaos experiments/game days; turn production learnings into preventative engineering.

Your Profile

• 8-10+ years in SRE/Production Engineering/DevOps or equivalent software engineering roles with ownership of high-availability systems.
• Strong software engineering fundamentals (one or more: Python, Go, Java, TypeScript) and proven automation mindset.
• Deep experience with Kubernetes (or container orchestration), cloud platforms (Azure/AWS/GCP), service meshes, and networking (DNS, TLS, HTTP, gRPC).
• Proficiency with IaC (Terraform, Helm) and CI/CD (Azure DevOps, GitHub Actions, Jenkins).
• Hands-on with observability stacks (Prometheus/Grafana, Open Telemetry, ELK/Elastic, Loki, Tempo, Sentry, Datadog, Splunk, New Relic) and alert design.
• Demonstrated leadership in incident response and postmortems, translating findings into systemic fixes.
• Solid understanding of resilient architectures: horizontal scaling, sharding/partitioning, caching, queues/streams (Kafka), backpressure, and graceful degradation.
• Excellent communication and collaboration skills; ability to influence and coach across squads.
• Good English, both written and spoken; German is a plus

We offer many benefits

• Company pension plan, capital-building offers, free Deutschlandticket & bicycle leasING, company restaurant
• Hybrid working: In addition to working in the office, you can also work remotely - within operational, regulatory and legal requirements.
