Working through real production problems, translating operational needs into product improvements, and filling a role that matters to both sides? This combination is rare.At Open-Xchange (OX), we develop open-source communication and collaboration software used by public sector organizations, telcos, and hosting providers to keep data secure and under their control. Our products cover email, collaboration, DNS security, and related services, and are used by millions of people worldwide.\nDiscover what OX offers you:\nWe work in a non-hierarchical organization that empowers everyone to take responsibility, stay focused, and contribute directly to the company’s success and customer value.\nWe value expertise and continuous professional development. Our professionals work closely with experienced colleagues, take ownership of their work, and continuously expand their skills.\nOpenness and diversity are core to OX. Different perspectives, backgrounds, and ways of thinking strengthen our collaboration and help us see the bigger picture.\nYour team:\nYou'll work in a dedicated cell built around one of our largest hosting customers - a provider running multiple brands on OX App Suite 8. Your closest collaborators are the Account Manager and Development Engineers, with Support looped in as needed. It's a largely independent seat, but you're one of several engineers across the company running the same model for other large accounts.Your new job:\nBe present in the customer relationship - regular calls, occasional on-site visits, and persistent continuity that the customer's technical teams know you by name and trust your word.\nBuild reference labs and generate reference configurations from them.\nParticipate in OX-internal development of those frameworks.\nAnalyze and resolve technical issues across the OX App Suite 8 stack. As L1/L2 is sitting with our customer your role is escalation-facing (L2/L3) taking ownership from escalation through to resolution and keeping the customer informed throughout.\nTranslate customer feature requests and operational requirements into clear input for internal product and development teams, and feedback internal constraints to the customer in terms they can act on.\nSupport the customer through upgrades, configuration changes, and new feature rollouts. Document solutions, workarounds, and deployment specifics - both for the customer and internally - and leave things better documented than you found them.Formal on-call is not part of this role.\n\nA typical day mixes customer and internal calls, hands-on lab and reference-configuration work, and technical documentation - with occasional escalation support when a customer integration needs deeper troubleshooting.\nLimited travel is required for customer-facing meetings (~1-2 per quarter) and company-internal meetings (~1 per quarter).\nThis is the tech stack you'll be working with:\nScale 1-5 where 5 means “hands-on depth expected on day one” and 1 means “we expect nothing and train it on the job”:OX App Suite 8 | 1 |\nKubernetes (Helm-based deployments) | 5 |\nMail infrastructure: Dovecot (CE / Pro), Postfix, IMAP/SMTP) | 2 |\nData layer: MariaDB, Redis | 3 |\nStorage: Object storage (S3-compatible), Rook Ceph | 2 |\nIdentity: Keycloak, LDAP | 2 |\nObservability: Prometheus, Grafana (or comparable stack) | 3 |\nTooling: Linux, Bash/Python, kubectl, Helm | 5 |\nNetworking: Istio (operational awareness, not configuration ownership) | 2 |\nYour background:\nProven ability to hold your ground in a technical disagreement with a customer or partner, and to stay composed and credible when a large account escalates - you can point to specific situations where you did this.\nSolid hands-on experience with Linux-based server environments.\nWorking knowledge of several core stack components -\nmail infrastructure (IMAP/SMTP, Dovecot or equivalent).\nrelational databases (MariaDB/MySQL).\ncontainerized deployments on Kubernetes.\nFamiliarity with monitoring and alerting (Prometheus/Grafana or equivalent) is part of staying ahead of issues rather than just reacting to them.\nWe don't expect OX App Suite or Dovecot experience, we train it.\nPractical experience troubleshooting distributed systems in production: reading logs across multiple services, correlating symptoms, and working through problems with a clear method.\nComfortable writing scripts to automate operational tasks or reproduce issues.\nExperience in a customer-facing technical role - support engineering, professional services, or similar - where you have taken ownership of an issue or requirement from first contact through to resolution.\nFamiliarity with Helm-based deployments and the operational patterns that come with running multi-brand or multi-tenant hosting environments.\nAble to work across teams and communicate technical details to people with different backgrounds: you can represent a customer's operational reality in an internal engineering discussion and translate an internal constraint back to the customer without losing either side.\nClear written communication is a requirement. Documentation and knowledge transfer are part of the job.\nGood written and spoken English is required as is fluency in German for this particular customer relationship.\nThis is what you get at OX:\nThe flexibility to work 100% remotely ensures a work environment that suits you best.\nFlexible working hours that allow you to successfully combine your home and family responsibilities with work. \nGetting together in-person for workshops and fun team events. \nTime off to volunteer - and mental health support when you need it.\nWe provide financial relief through corporate benefits and a subsidy for ergonomic chairs and desks.\nWe can discuss further location-related benefits together in an initial talk.\nJoin the team:\nJoin us in our fight for an open internet and deliver added value!

She will be able to discuss current opportunities and tell you more about our exciting vision and mission @OX.","description_format":"text","description_chars":6238,"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":"German","level":"Advanced (C1)","optional":false},{"language":"English","level":"All levels","optional":false}]},"benefits":["Flexible schedule","Professional development"],"hiring_locations":[{"name":"Germany","iso":"DE","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Office & Productivity Software","Email Hosting & Delivery","DNS Services"],"lifecycle":[{"event":"open","at":"2026-09-29T06:46:03Z"}],"visa":[],"liveness":{"score":61,"band":"ok","label":"Likely open","p_open":1,"p_active":0.818,"p_room":0.75,"age_days":29,"expected_fill_days":35,"reasons":["conf:1","win:late"],"computed_at":"2026-10-21T05:46:15Z"},"pay":null,"html_url":"https://alion.io/job/ox-senior-professional-services-engineer-ox-app-suite-mfd","json_url":"https://alion.io/job/ox-senior-professional-services-engineer-ox-app-suite-mfd.json","meta":{"generated_at":"2026-10-21T10:38:30Z","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_verified","counted_by":"address","units_charged":1,"used_today":15029,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"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":52356},"rest":"https://alion.io/mcp/rest/get_company?id=52356"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fox-senior-professional-services-engineer-ox-app-suite-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%2Fox-senior-professional-services-engineer-ox-app-suite-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%2Fox-senior-professional-services-engineer-ox-app-suite-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/ox-senior-professional-services-engineer-ox-app-suite-mfd\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fox-senior-professional-services-engineer-ox-app-suite-mfd"}]}
