Senior Backend-Entwickler - Agents (100% Remote / German-Speaking)
Powerprozesse
Wir suchen Senior Developer, die in unserem vollständig remoten Team an unseren Agenten arbeiten. Wenn du Komplexität magst und willst, dass deine Arbeit wirklich etwas bewegt, passt du zu uns.
Über uns
Hausverwalter.ai ist eine All-in-One-Plattform für Hausverwaltungen, mit Funktionen wie Inbox, CRM, Dokumenten, Telefonie, Video Calls, Team Chat und KI-Agenten. Unsere Mission ist es, alles zu automatisieren, was ein Hausverwalter tut.
Über die Rolle
Unsere Plattform ist von Tag eins an agentisch gedacht. Bevor wir überhaupt die UI geplant haben, haben wir geplant, wie Agenten mit der Software arbeiten. Denk dran – unser Ziel ist, die ganze Branche zu automatisieren, und das meinen wir ernst.
Heute gibt es für fast alles, was der Nutzer in der UI machen kann, ein Agenten-Tool, und der Co-Pilot (der tägliche Assistent des Nutzers) kann alles für ihn übernehmen, sogar den Dark Mode an- und ausschalten.
Aber der Co-Pilot ist erst der Anfang. Die eigentliche Herausforderung sind die autonomen Agenten. Dazu unten mehr.
Woran du arbeiten wirst
Inbox-Agents: Autonome Agenten, die anspringen, sobald in einem Ticket etwas Neues passiert. Kunden trainieren sie selbst ODER nehmen einfach eine der Vorlagen, die du für sie baust. Diese Agenten können heute schon komplette komplexe Abläufe allein übernehmen und sind einer der Hauptgründe, warum sich Kunden für unsere Software interessieren. Aber wann sollte ein Agent an einen Menschen abgeben, statt selbst zu Ende zu machen? Wie stellen wir sicher, dass er sich an den Prozess hält? Das sind deine Fragen.
Harness Engineering: Der Agent hat über 100 Tools. Aber er muss eine Anfrage so verstehen, wie ein Hausverwalter sie versteht, und nicht so, wie die Begriffe außerhalb der Branche klingen. Was gehört in den System Prompt, was in Skills?
Knowledge Base: Unsere Plattform hat eine eigene Knowledge Base, ähnlich wie Notion. Komplett selbst gebaut und gedacht als kollektives Gehirn des Unternehmens. Aber sollte die KI auch von selbst „lernen"? Und wenn ja, wann? Und wie machen wir die Suche in der Knowledge Base besser — über bessere Tools, System Prompts oder Skills?
Voice-Agents: Dieselben Agenten, nur am Telefon — auf LiveKit gebaut, die Anrufe genauso abwickeln wie unsere Text-Agenten Tickets.
LLM Infrastructure. Das richtige Modell für die jeweilige Aufgabe wählen, per Caching und Streaming die Latenz drücken, bei Provider-Ausfällen sauber neu versuchen, Context kompakt halten, die RAG-Suche optimieren, Usage über alle Provider tracken, Kosten senken und mit Evals prüfen, was wirklich besser ist.
Unser minimalistischer Tech Stack
Alles ist TypeScript. Vom Datenbankschema bis ins Frontend.
Backend: Convex (Datenbank & Serverless Functions)
Frontend: Next.js , React, Tailwind, shadcn/ui
Technologien, die dir begegnen werden: Vercel AI SDK, Convex Agent Component
Gehalt
5000 – 6000 Euro brutto, mit Raum für Wachstum und Beförderungen in den kommenden Monaten und Jahren
Benefits
100 % remote
Flexible Arbeitszeiten
So viele KI-Tokens, wie du brauchst
Wir sind eigenfinanziert und profitabel (und verbrennen kein VC-Geld, um zu überleben)
Kleines Team, echte Verantwortung — was du baust, geht auch wirklich live
Schnelle Entscheidungen, keine sinnlosen Meetings und keine Freigabeschleifen, durch die du dich kämpfen musst
Unsere Werte
Dinge fertig machen, jeder Tag zählt
Transparenz und Ehrlichkeit, gerade wenn es unangenehm wird
Nach Großem streben – dich und andere ständig fordern
Wenn du genauer sehen willst, was wir bauen: Schau auf unserem YouTube-Kanal vorbei — kleiner Hinweis, der ist auf Deutsch.
Du bist
fließend in Englisch und Deutsch
ein erfahrener Entwickler mit mehr als 2 Jahren Erfahrung im Bauen von Agenten für den Produktivbetrieb
AI-native. Du hast agentische Features ausgeliefert, auf die sich echte Nutzer verlassen, und du hast eine Meinung zu Retrieval, Evals, Tool-Design und dazu, wo die heutigen Spitzenmodelle an ihre Grenzen kommen.
in erster Linie Builder. Du bringst lieber heute eine grobe v1 raus, als drei Wochen lang die perfekte zu planen.
auf dem neuesten Stand bei neuen KI-Modellen und der Forschung
jemand, der fast seinen gesamten Code mit KI schreibt
es gewohnt, autonom zu arbeiten und volle Verantwortung für deine Aufgaben zu übernehmen
unter Leistungsdruck sogar noch besser
schnell darin, Neues zu lernen, und siehst dich als Generalist, nicht als Spezialist
Dein Techstack :
Ist nicht wichtig, da bei uns KI deinen Code schreiben wird.
