Wir sind ein Software-Entwickler mit Erfahrung aus hunderten von individuellen Projekten für Enterprise- und Mittelstands-Kunden.\nKurze Wege, ehrliches Feedback, keine politischen Spielchen. Keine Hierarchie-Ebenen zwischen dir und den Leuten, die Entscheidungen treffen.\nDeine Aufgaben\nDu arbeitest in Kundenprojekten bei großen Unternehmen und öffentlichen Auftraggebern, eingebettet in deren Teams, mit voller Verantwortung für deinen Bereich.\nFullstack-Entwicklung in Enterprise- und regulierten Umgebungen\nArchitektur mitgestalten, nicht nur umsetzen\nCode generieren, reviewen und refactoren mit Claude Code, Copilot oder Cursor\nCode Reviews und technisches Mentoring im Team\nAbstimmung mit Product Ownern, UX und DevOps\nDie meisten kommen ein bis zwei Tage die Woche in eins der Büros. Zwang ist das aber keiner. Beim Kunden vor Ort bist du nur für einzelne Termine alle paar Wochen, meist in Frankfurt am Main.\nWo du landest\nJe nach Projekt und deiner Erfahrung:\nGroßkonzerne wie Deutsche Bahn / DB Systel (eisenbahnspezifische Domänen: Fahrplanmanagement, Vertrieb, Leit- und Sicherungstechnik)\nÖffentlicher Sektor / Behörden (z. B. Bundesagentur für Arbeit, ITZBund, Bundesdruckerei) - regulierte Umgebungen, Barrierefreiheit, Security by Design\nEnterprise- und Mittelstands-Kunden aus verschiedensten Branchen\nUnsere Kunden besetzen diese Projekte fast nur mit Festangestellten. Deshalb suchen wir dich in Festanstellung.\nErfahrung in einem dieser Umfelder ist ein starkes Plus - sag uns in den Fragen, wo du herkommst.\nWas du mitbringst\nSenior-Level. Unsere Kunden brauchen Leute, die ab Tag eins liefern und eigenständig arbeiten.\nBackend-Kern (das erwarten wir):\nJava (17+) und Spring Boot (Microservices, Domain Driven Design)\nREST-Schnittstellen und relationale Datenbanken, vor allem PostgreSQL\nDocker und Kubernetes\nTestgetriebene Entwicklung (TDD) mit JUnit - Tests gehören bei uns zur Definition of Done, nicht in die Nacharbeit\nApache Kafka / asynchrone Kommunikation\nCI/CD (Jenkins, GitHub Actions), Git, agiles Arbeiten\nFrontend (das erwarten wir):\nAngular mit TypeScript\nVon Vorteil (kein Muss):\nLLM-Integration in Fachanwendungen (RAG, Tool-Calling/MCP, Agenten), gern mit einem Projektbeispiel\nKotlin, Camunda (BPMN-Prozessautomatisierung)\nAWS oder Azure, JPA/Hibernate\nMonitoring (Grafana, Prometheus), Tests im Frontend (Jest, Playwright, Cypress)\nBarrierefreiheit (BITV 2.0 / WCAG AA), DevSecOps / Security by Design (öffentlicher Sektor)\nDu musst nicht alles können. Wichtig ist, dass du auf beiden Seiten sicher bist und dich schnell in neue Stacks reinfindest.\nAI-Tools sind Pflicht, kein Bonus\nClaude Code, Copilot, Cursor: Damit musst du produktiv arbeiten können. Nicht weil wir hip sein wollen, sondern weil unsere Kunden das erwarten und wir auch so arbeiten. Wenn du AI-Tools für einen Hype hältst und lieber alles selbst tippst: falsche Firma. Intern investieren wir in deine AI-Skills.\nWas wir bieten\nHomeoffice, Büro oder Mix, du entscheidest\nMacBook (außer der Kunde stellt eigene Hardware)\nVerschiedene Kunden, verschiedene Projekte\nDie Gründer sind deine direkten Ansprechpartner\nInternes Upskilling in AI-Entwicklung\nBewerbung\nLebenslauf reicht. Kein Anschreiben nötig. Nach einer kurzen Video-Frage-Runde (2×90 Sekunden) melden wir uns innerhalb weniger Tage.","description_format":"text","description_chars":3405,"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}]},"benefits":["Apple Macbook"],"hiring_locations":[{"name":"Germany","iso":"DE","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-10-27T17:49:55Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":47,"reasons":["conf:0","win:early"],"computed_at":"2026-10-28T05:59:10Z"},"pay":null,"html_url":"https://alion.io/job/rockstardevelopers-senior-fullstack-entwickler-java-angular-mwd-4","json_url":"https://alion.io/job/rockstardevelopers-senior-fullstack-entwickler-java-angular-mwd-4.json","meta":{"generated_at":"2026-10-28T21:03:53Z","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":29013,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-29T00:00:00Z"}},"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":685664},"rest":"https://alion.io/mcp/rest/get_company?id=685664"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Frockstardevelopers-senior-fullstack-entwickler-java-angular-mwd-4"},{"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%2Frockstardevelopers-senior-fullstack-entwickler-java-angular-mwd-4"},{"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%2Frockstardevelopers-senior-fullstack-entwickler-java-angular-mwd-4"},{"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/rockstardevelopers-senior-fullstack-entwickler-java-angular-mwd-4\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Frockstardevelopers-senior-fullstack-entwickler-java-angular-mwd-4"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3348136}},{"tool":"search_jobs","arguments":{"company":"rockstardevelopers.de","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3348136},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
