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. Du übernimmst eigene Features von der Schnittstelle bis zur Oberfläche, erfahrene Kolleginnen und Kollegen sind ansprechbar.\nFullstack-Entwicklung mit Java/Spring Boot und Angular\nFeatures eigenständig umsetzen, testen und ausliefern\nCode generieren, reviewen und refactoren mit Claude Code, Copilot oder Cursor\nCode Reviews geben und bekommen\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: Großkonzerne wie Deutsche Bahn / DB Systel, öffentlicher Sektor und Behörden, Enterprise- und Mittelstands-Kunden aus verschiedensten Branchen. Unsere Kunden besetzen diese Projekte fast nur mit Festangestellten. Deshalb suchen wir dich in Festanstellung.\nWas du mitbringst\nMindestens drei Jahre Berufserfahrung als Entwickler, gezählt nach Ausbildung oder Studium.\nDas erwarten wir:\nJava (17+) und Spring Boot\nAngular mit TypeScript\nREST-Schnittstellen und relationale Datenbanken, vor allem PostgreSQL\nTests mit JUnit als Teil der Definition of Done\nGit, CI/CD, agiles Arbeiten\nVon Vorteil (kein Muss):\nLLM-Integration in Anwendungen (RAG, Tool-Calling, Agenten), auch aus einem Nebenprojekt\nDocker und Kubernetes, Kafka\nKotlin, Camunda (BPMN-Prozessautomatisierung), Keycloak/OAuth 2.0\nAWS oder Azure, JPA/Hibernate\nFrontend-Tests (Jest, Playwright, Cypress), Barrierefreiheit (BITV 2.0 / WCAG AA)\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. Unsere Kunden erwarten das, und wir arbeiten auch so. 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":2723,"description_truncated":false,"requirements":{"experience_years_min":3,"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-fullstack-entwickler-java-angular-mwd-mid-level","json_url":"https://alion.io/job/rockstardevelopers-fullstack-entwickler-java-angular-mwd-mid-level.json","meta":{"generated_at":"2026-10-28T22:20:16Z","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":30222,"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-fullstack-entwickler-java-angular-mwd-mid-level"},{"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-fullstack-entwickler-java-angular-mwd-mid-level"},{"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-fullstack-entwickler-java-angular-mwd-mid-level"},{"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-fullstack-entwickler-java-angular-mwd-mid-level\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Frockstardevelopers-fullstack-entwickler-java-angular-mwd-mid-level"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3348132}},{"tool":"search_jobs","arguments":{"company":"rockstardevelopers.de","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3348132},"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.
