Description
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.
