TypeFull-time job

Posted1 hour ago
Do you want to own infrastructure rather than just keep it running? Here, the full stack is yours – from the Proxmox cluster in our own data center, through firewalls and VPNs, to AWS and the deployment pipelines.
Testsieger is one of Germany's largest consumer platforms: 4.2 million products, test reviews, customer ratings and an integrated price comparison that guides millions of users to the right purchase. A team of 20 with short decision paths and no corporate overhead – and an established engineering team in Portugal.
You will be the technical owner of our infrastructure – with a colleague at your side whom you'll grow, and an engineering team that counts on you.
Tasks
Own the operation of our Linux server landscape: on-premise cluster (Proxmox, ZFS) and AWS
Run and harden network and security: firewalls, VPN, access control, certificates, hardening – including the network link to our largest partner
Automate with Ansible and keep infrastructure versioned, reproducible and documented
Maintain our container platform (Docker, Nomad, Traefik) and CI/CD pipelines (GitHub Actions) so teams ship fast and safely
Administer MySQL in production: backups, performance, recovery
Extend monitoring, logging and alerting (Grafana, New Relic) and drive incidents to root cause
Act as sparring partner for Engineering, Data and Product – and explain why things are built the way they are
Requirements
Several years running Linux server environments (Debian/Ubuntu) – you know how to get systems from A to B without assistance
Solid networking: TCP/IP, routing, DNS, load balancing, firewall and VPN administration
Proven infrastructure security practice: hardening, access control, security best practices
Ansible in production, container orchestration (Nomad, Kubernetes or similar), CI/CD pipelines
Experience with AWS or a comparable public cloud
MySQL administration in production
Bash and Python – for tooling, not just one-liners
Monitoring, logging and troubleshooting are your craft, not an afterthought
Plus: Terraform, RabbitMQ, Redis, Zero Trust concepts
Fluent English; German is a plus, not a requirement
Benefits
Full technical ownership of a real hybrid stack (on-premise + cloud) – you make the decisions, not an architecture board
Well funded company, attractive salary
Ownership culture with short paths: you talk directly to the CEO
Modern stack: Proxmox, AWS, Ansible, Nomad, Docker, MySQL, Python, GitHub Actions, Next.js ecosystem
Remote from Portugal, with regular visits to Osnabrück and colleagues already based in Portugal
If you see infrastructure as your product and want to develop it with real responsibility – apply now. We're looking forward to meeting you.
