What your new challenge will look like

• In this role, you will design and develop backend components that form the backbone of our digital products, using Java and Spring Boot as your primary toolkit. You will implement and maintain well‑structured RESTful APIs, following best practices in API design to ensure reliability, clarity, and long-term maintainability.

• You will be involved in the full software development lifecycle—from ideation and implementation to testing and deployment—taking ownership of clean, efficient, and maintainable code. Working closely with our frontend, DevOps, and QA teams, you will help ensure seamless integration across our systems and contribute to delivering a smooth, high-quality user experience.

• As part of our commitment to continuous improvement, you will participate in code reviews, share ideas, and help us evolve our engineering practices. This is a great opportunity to deepen your backend expertise while working with modern tools and a supportive team.

Why you belong at 4flow

• You bring at least 3 years of experience in backend development and a solid academic foundation with a degree in computer science, software engineering or a related field.

• You feel confident working with Java, Spring Boot, and modern API design principles, and you are eager to grow your expertise even further.

• It’s a plus if you’ve already gained experience with technologies like Docker, AWS, SQL or NoSQL databases, Domain‑Driven Design, CI/CD pipelines, Python, microservices, or even AI/ML integration—though none of these are mandatory. What matters most is your curiosity, your willingness to learn, and your drive to develop impactful backend solutions.
