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.\nTestsieger 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.\nYou 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.\nTasks\nOwn the operation of our Linux server landscape: on-premise cluster (Proxmox, ZFS) and AWS\nRun and harden network and security: firewalls, VPN, access control, certificates, hardening - including the network link to our largest partner\nAutomate with Ansible and keep infrastructure versioned, reproducible and documented\nMaintain our container platform (Docker, Nomad, Traefik) and CI/CD pipelines (GitHub Actions) so teams ship fast and safely\nAdminister MySQL in production: backups, performance, recovery\nExtend monitoring, logging and alerting (Grafana, New Relic) and drive incidents to root cause\nAct as sparring partner for Engineering, Data and Product - and explain why things are built the way they are\nRequirements\nSeveral years running Linux server environments (Debian/Ubuntu) - you know how to get systems from A to B without assistance\nSolid networking: TCP/IP, routing, DNS, load balancing, firewall and VPN administration\nProven infrastructure security practice: hardening, access control, security best practices\nAnsible in production, container orchestration (Nomad, Kubernetes or similar), CI/CD pipelines\nExperience with AWS or a comparable public cloud\nMySQL administration in production\nBash and Python - for tooling, not just one-liners\nMonitoring, logging and troubleshooting are your craft, not an afterthought\nPlus: Terraform, RabbitMQ, Redis, Zero Trust concepts\nFluent English; German is a plus, not a requirement\nBenefits\nFull technical ownership of a real hybrid stack (on-premise + cloud) - you make the decisions, not an architecture board\nWell funded company, attractive salary\nOwnership culture with short paths: you talk directly to the CEO\nModern stack: Proxmox, AWS, Ansible, Nomad, Docker, MySQL, Python, GitHub Actions, Next.js ecosystem\nRemote from Portugal, with regular visits to Osnabrück and colleagues already based in Portugal\nIf you see infrastructure as your product and want to develop it with real responsibility - apply now. We're looking forward to meeting you.","description_format":"text","description_chars":2698,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":[],"hiring_locations":[{"name":"Portugal","iso":"PT","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Price Comparison","Online Reviews & Ratings"],"lifecycle":[{"event":"open","at":"2026-10-02T15:38:13Z"}],"visa":[],"liveness":{"score":10,"band":"cold","label":"Long shot","p_open":1,"p_active":0.295,"p_room":0.35,"age_days":18,"expected_fill_days":7,"reasons":["conf:0","win:tail"],"computed_at":"2026-10-07T05:47:15Z"},"pay":null,"html_url":"https://alion.io/job/testsieger-senior-system-engineer-platform-security-mfd","json_url":"https://alion.io/job/testsieger-senior-system-engineer-platform-security-mfd.json","meta":{"generated_at":"2026-10-08T01:21:20Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":2448,"day_limit":5000,"remaining_today":2552,"minute_limit":60,"resets_at":"2026-10-09T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":688419},"rest":"https://alion.io/mcp/rest/get_company?id=688419"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftestsieger-senior-system-engineer-platform-security-mfd"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Ftestsieger-senior-system-engineer-platform-security-mfd"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Ftestsieger-senior-system-engineer-platform-security-mfd"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/testsieger-senior-system-engineer-platform-security-mfd\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftestsieger-senior-system-engineer-platform-security-mfd"}]}
