Java Fullstack Developer

This contract role in Gothenburg will develop customer-facing portal features, with end-to-end ownership from design and implementation through testing, deployment, and production operation. The core requirements are strong Java and Spring Boot, JavaScript, TypeScript, React, API development and integration, relational databases, AWS, CI/CD, Git, and automated testing. The successful developer will also bring production experience and an understanding of secure, scalable, reliable software, while collaborating in an Agile product team. Event-driven technologies, observability, AI-assisted development tools, and UX collaboration are additional merits rather than core requirements. The structured input specifies 5–10 years of experience and contract employment; work mode is not specified, and fluent English is required.
