Kaputte Prozesse, zusammengeklebte Tools, null Skalierbarkeit.\nCapitalFlow ist die Plattform, die Berater live im Kundengespräch nutzen - ein durchgängiges System von der Datenerfassung bis zum fertigen Gutachten. Kein Konzept. Ein Produkt in täglicher Anwendung.\nÜber 800 zahlende Nutzer. 400% Wachstum im letzten Jahr. 100% bootstrapped. Und wir fangen gerade erst an.\nAufgaben\nDu arbeitest direkt mit dem CTO - nicht als Ticket-Abarbeiter, sondern als jemand, der Features eigenständig end-to-end umsetzt. Von der Konzeption bis zum Production Deployment.\nWas das konkret bedeutet: Du übernimmst Verantwortung für ganze Feature-Bereiche, arbeitest an Architekturentscheidungen mit und siehst, was du gebaut hast, am nächsten Tag in echten Kundengesprächen\nQualifikation\nMind. 4 Jahre Erfahrung als Fullstack-Entwickler im Node.js-Ökosystem\nFundierte TypeScript-Kenntnisse\nErfahrung mit PostgreSQL\nNext.js und/oder NestJS - idealerweise beides, eines davon ist Pflicht\nDu kannst Features eigenständig end-to-end umsetzen - von Konzeption bis Production Deployment\nGrundkenntnisse in AWS\nBonus: Erfahrung mit Monorepos (Turborepo), Testing mit Jest und/oder Playwright\nDu brauchst kein Finanzwissen. Du brauchst Lust, ein komplexes Produkt zu bauen, das eine ganze Branche verändert.\nBenefits\nEchtes Produkt, echte Nutzer. Was du baust, nutzen Menschen am nächsten Tag in echten Kundengesprächen. Kein Feature-Friedhof.\nOwnership. Kleines Team, kurze Wege, große Hebel. Keine fünf Hierarchieebenen zwischen dir und einer Entscheidung.\nWachstum. 400% im letzten Jahr - und das ist erst der Anfang. Wer früh Verantwortung übernimmt, wächst mit. Inklusive der Möglichkeit auf Unternehmensanteile.\nOffice. Altbau-Stadtvilla nahe dem Hölderlinplatz in Stuttgart. Hybrid - aber ein Büro, in dem man gerne ist.\nAusstattung. MacBook, alles was du brauchst.\nTeam. Gemeinsame Events, Reisen, ein Team das zusammen baut und zusammen feiert.\nUnser Prozess ist kurz und direkt:\nKennenlernen - kurzes Gespräch, ob die Richtung passt\nTechnisches Interview - Architektur und Code\nProbetag im Stuttgarter Office - gemeinsam arbeiten, Team kennenlernen\nAngebot & Start\nWenn du bereit bist, an einem Produkt zu arbeiten, das wirklich genutzt wird - bewirb dich jetzt.","description_format":"text","description_chars":2447,"description_truncated":false,"requirements":{"experience_years_min":4,"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":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Financial Services","Financial Software & Embedded Finance"],"lifecycle":[{"event":"open","at":"2026-09-14T00:51:38Z"}],"visa":[],"liveness":{"score":6,"band":"cold","label":"Long shot","p_open":1,"p_active":0.212,"p_room":0.28,"age_days":203,"expected_fill_days":29,"reasons":["conf:2","win:tail","crowd:"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/capital-flow-full-stack-engineer-mwd-typescriptnode-js-fintech-start-up-stuttgart","json_url":"https://alion.io/job/capital-flow-full-stack-engineer-mwd-typescriptnode-js-fintech-start-up-stuttgart.json","meta":{"generated_at":"2026-10-31T04:19:41Z","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":5985,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":672745},"rest":"https://alion.io/mcp/rest/get_company?id=672745"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcapital-flow-full-stack-engineer-mwd-typescriptnode-js-fintech-start-up-stuttgart"},{"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%2Fcapital-flow-full-stack-engineer-mwd-typescriptnode-js-fintech-start-up-stuttgart"},{"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%2Fcapital-flow-full-stack-engineer-mwd-typescriptnode-js-fintech-start-up-stuttgart"},{"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/capital-flow-full-stack-engineer-mwd-typescriptnode-js-fintech-start-up-stuttgart\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcapital-flow-full-stack-engineer-mwd-typescriptnode-js-fintech-start-up-stuttgart"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":881171}},{"tool":"search_jobs","arguments":{"company":"capital-flow.de","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":881171},"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.
