At Intraway, we build Symphonica, a cloud-native, AI-powered platform that helps telecom companies orchestrate and automate complex services at scale.

We're looking for a Senior Backend Engineer to design, build, and operate Symphonica's backend microservices (Java, Spring Boot, event-driven architectures). You'll own your work from design to production — and this is an AI-native role: AI-assisted development is part of the regular workflow, while you stay fully accountable for quality, security, and maintainability.

What You'll Do

- Design, build, test, deploy, and operate scalable microservices with Java, Spring Boot, and event-driven architectures.
- Own changes end to end: analysis, design, implementation, production, and operation.
- Use AI coding assistants and agents to accelerate development — critically reviewing and validating every output.
- Build and maintain automated tests (unit, integration, contract, smoke).
- Troubleshoot production issues and improve performance, reliability, and observability.




- Refactor and modernize components while managing compatibility and operational risk.
- Collaborate with Product, QA, Architecture, SRE, and frontend teams; contribute to code reviews and engineering standards.

What You'll Bring

- 5+ years building backend applications with Spring Boot and microservices.
- Experience designing and operating distributed systems and REST APIs.
- Event-driven architectures and streaming platforms (e.g., Apache Kafka).
- Relational databases, SQL, JPA/Hibernate, and NoSQL (e.g., MongoDB).
- Linux, Git, Maven/Gradle, and basic scripting (Bash, Python, or similar).
- Strong automated testing, troubleshooting, and reliability practices.
- Hands-on use of AI coding assistants or agents in professional workflows, with the judgment to review and validate AI-generated output.
- Intermediate
