We are looking for a strong Backend Developer to join our SaaS platform development.

This is not a generic Java backend role. Our project is built around Kotlin, and we need someone with real commercial experience working on production backend systems.
 

Project context:
We already have an existing backend, an active development process, and a growing product with multiple modules. The team already includes 2 backend developers, 1 frontend developer, a PM, and a QA engineer. We need another backend developer who can work inside an established codebase, understand business logic, collaborate effectively with the team, and deliver reliable backend features without breaking existing flows.
 

Core stack:
- Kotlin
- Spring Boot 3.x
- JDK 21
- Spring Data JPA / Hibernate
- PostgreSQL
- Flyway
 

Important experience:
- Spring Security + JWT

- improving transactional consistency in sensitive flows
- integrating external services such as storage, notifications, and AI-related features

- ability to read and extend existing code, not only build from scratch
- careful engineering mindset
- understanding of edge cases, security, permissions, and data isolation
- ability to use modern AI-assisted engineering tools effectively as part of a fast and reliable development workflow

Modern workflow:
We strongly prefer developers who are comfortable using modern AI-assisted engineering tools such as ChatGPT, Claude, Cursor, GitHub Copilot, Antigravity, or similar tools in their daily workflow. We value people who can use AI to move faster, while still thinking independently, reviewing generated code critically, and maintaining production-level quality.
 

Please do not apply if:
- your background is mainly Java and Kotlin is only minor
- you mostly worked on simple CRUD apps
- you are not comfortable with existing production codebases
- you do not actively use modern AI-assisted development tools in your workflow
- you need step-by-step supervision for every task
