Backend Software Engineer
Pubblicato il 10-09-2026 - Casavo in Balgano
The Company
Casavo is a next-generation digital real estate agency that leverages technology to simplify and expedite the process of buying and selling real estate. Our platform is used daily by hundreds of agents across Italy and France - and what you build will be at the core of how they work.
The Role: Learn by Building on a Real System
We are rebuilding Casavo’s technology foundation: a cleaner, modular architecture with clear domain boundaries and robust, predictable APIs. This is what enables AI agents and automations to work reliably across the stack.
You’ll help build the platform that powers Casavo AI.
To get there, we are migrating our core systems from a legacy Scala monolith to a modern Kotlin modular monolith.
You won’t be working on toy projects. From day one, you’ll contribute to production software, supported by a senior team that values mentorship, thoughtful code reviews, and blameless engineering.
If you’re early in your career, curious about backend systems, and motivated to write clean Kotlin on a product that matters, this role is for you.

What You’ll Do

- Write SQL queries and learn how indexing and pagination impact real production systems
- Help migrate business logic from our legacy Scala system
- Write automated tests as a natural part of your development workflow
- Participate in code reviews, architecture discussions, and team rituals
