Platform & Reliability Engineer (all genders)

Description

We are hiring a permanent, full-time Platform and Reliability Engineer of any gender, with a start as soon as possible.

The team works remote-first. Because you can reach one of our offices in Berlin, Cologne, Hamburg or Munich, you may choose hybrid or fully on-site work.

You will hold architectural responsibility for the shared infrastructure that several development teams depend on, including API gateway and ingress, persistent storage, secrets and identity, edge security, and observability.

Much of this estate has grown over time and is only partly documented, so you will work through it in depth, find known weak spots, judge aging components by whether to build or buy, and decide what to fix, replace or retire.

The company is still growing and changing. It values direct communication and open feedback.

Responsibilities

• Take ownership of API gateway and ingress (Kong, Nginx Ingress), persistent storage (Ceph, Longhorn), secrets and identity (Vault, Keycloak), edge security and WAF (Cloudflare), and the observability stack.
• Design and set up an on-call process with runbooks for platform and infrastructure incidents, where none exists today.
• Improve observability by introducing distributed tracing, SLOs/SLIs and useful dashboards, building on Prometheus, Grafana, Alloy and OpenTelemetry.
• Bring fundamentals such as load balancing, caching, sharding, replication and consistency trade-offs into system design reviews for new and existing services.
• Act as the technical authority for several teams on shared infrastructure, document what you know and pass it on, so that critical knowledge is not held by one person.
• Resolve known risks and cut single points of failure across the platform.
• Travel occasionally for datacenter visits and team offsites.

Requirements

• 7+ years in platform, infrastructure or SRE roles, ideally with end-to-end responsibility for a private cloud or IaaS platform.
• Hands-on production experience with distributed storage (Ceph) and Kubernetes persistent storage (Longhorn or similar).
• Experience running API gateways or ingress (Kong, Nginx Ingress or similar), including diagnosing CORS and rate limiting problems.
• Experience with CDN and edge security, DDoS mitigation and WAF configuration (for example Cloudflare), and designing firewall rules.
• A solid grasp of system design fundamentals (load balancing, caching, sharding and replication, consistency models, message queues) and the ability to weigh them against real trade-offs.
• Professional English, as it is the working language.
• Ability to work calmly in grown, partly undocumented systems, balancing pragmatism with precision: fix what is broken and retire what is dead instead of rewriting everything.
• Enjoy being the go-to technical person across teams and sharing and documenting what you know.
• Desirable: experience designing or improving observability (tracing, metrics, SLOs/SLIs) with tools such as Prometheus, Grafana and OpenTelemetry.
• Plus: experience with Vault, Keycloak, NATS, and building on-call processes and incident runbooks from scratch.
• Plus: German language skills, certifications (CKA/CKS, Ceph training), and experience with virtualization platforms (Proxmox, OpenStack).

Conditions

Full-time, permanent position.

Remote work in Germany, with optional hybrid or on-site work at Berlin, Cologne, Hamburg or Munich.

The company is an equal opportunity employer and welcomes applicants regardless of background.
