Software Engineer (m/w/d)

Reltix is a technology-driven company aiming to revolutionize the real estate industry through a unified operating system for property management. The Software Engineer will design and develop backend services and APIs, ensuring that property data is accurate and accessible, while also collaborating closely with founders and the operations team to drive product development.

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:

• 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
• IaaS & IaC: AWS (or equivalent cloud), Terraform (or Pulumi), and comfort working on platform/infrastructure when needed
• AI-powered product features, event-driven architectures, third-party API integrations, or early-stage experience
