Job description
Software Engineer (m/w/d)
Company Overview
The German property management industry is one of the oldest and least digitalised service sectors in the country. reltix has actively chosen a third path. Inside a single technical infrastructure, we unite operational management and the knowledge that comes from actually offering the service with the digitalisation of data from the properties we manage. That gives us an operating system for property management: the system teams run on, the source of truth for every property, and the platform workflows and partners plug into. Founded in 2025, we've gone from zero to 4,000+ customers and a team of over 30+ people in little more than a year.
Job Summary
We're building the operating system of the real estate industry, and the product is where it all comes together: the software managers work in, the APIs the voice agent and chatbot run on, the logic that turns a messy real-world request into a clean, automated action. This is a backend-first role on a small, senior team that ships fast.
Key Responsibilities
- Design and build the backend services and APIs at the core of the product: data models, business logic, and the integrations everything else depends on.
- Ship features end to end, from schema and API to the behaviour users experience, and grow into the frontend as far as your curiosity takes you.
- Build the systems that power our AI surfaces, with the full context of the property available to the voice agent, the owner chatbot, and the manager software.
- Integrate with third-party systems across the real estate and financial ecosystem.
- Work directly with the founders and operations team to decide what to build, then ship it fast and iterate.
Requirements / Qualifications
- 3+ years of professional engineering experience, with real depth on the backend.
- Strong in a modern backend language (preferably Golang/Python), comfortable designing data models, APIs, and services from scratch.
- Experience shipping in a modern web stack (React + TypeScript).
- Solid with relational databases and a good sense for structuring data well.
- Curiosity about the frontend and a genuine wish to go full-stack.
- A pragmatic, shipping mindset and ownership as a default: you see something broken and you fix it.
Preferred Qualifications
- (IaaS & IaC): AWS (or equivalent cloud), Terraform (or Pulumi), and comfort working on platform/infrastructure when needed.
- Bonus: AI-powered product features, event-driven architectures, third-party API integrations, or early-stage experience.
