Role Description

We are seeking an experienced Senior Backend Java Developer with extensive expertise in Java and Spring Boot to design and implement modern, scalable, API-first backend solutions. The successful candidate will transform functional and architectural specifications into high-quality technical designs while contributing to the evolution of a robust, cloud-native platform. This role requires a strong technical leader capable of mentoring a small engineering squad, driving backend architecture decisions, and delivering secure, maintainable, and highly scalable services within an international Agile environment.

Key Responsibilities

• Design and implement scalable, API-first backend solutions using Java and Spring Boot.
• Translate functional and architectural requirements into robust technical designs.
• Lead and mentor a squad of 2–3 backend engineers, promoting engineering best practices and code quality.
• Contribute to architecture decisions, ensuring clear separation of concerns, bounded contexts, maintainability, and operational simplicity.
• Develop high-quality, well-tested code through unit, integration, and contract testing.
• Design and build RESTful APIs and event-driven services aligned with OpenAPI and AsyncAPI specifications.
• Enforce API governance standards and backend development best practices.
• Develop and maintain integrations with third-party systems using JSON, XML, and XSD.
• Design, model, and optimize MongoDB schemas while managing database migrations and transactional consistency patterns.
• Apply secure development practices, including OAuth2, OpenID Connect (OIDC), and JWT authentication mechanisms.
• Support CI/CD pipelines, trunk-based development, and cloud-native deployment practices using Docker, Kubernetes, and Helm.
• Collaborate closely with architects, business analysts, UX designers, QA engineers, DevOps, and frontend developers in an international environment.
• Participate actively in Agile/Scrum ceremonies and contribute to continuous improvement initiatives.

Qualifications

• Extensive professional experience developing backend applications with Java and Spring Boot.
• Strong experience designing scalable, API-first architectures.
• Proven ability to lead technical initiatives and mentor engineering teams.
• Solid understanding of software architecture principles, including separation of concerns and domain-driven design concepts such as bounded contexts.
• Experience developing RESTful APIs and event-driven architectures.
• Strong knowledge of OpenAPI and AsyncAPI specifications.
• Experience working with JSON, XML, and XSD, including resilient integrations with third-party systems.
• Hands-on experience modelling and optimizing MongoDB databases.
• Knowledge of database migrations and transactional consistency patterns.
• Strong understanding of application security, including OAuth2, OpenID Connect (OIDC), and JWT.
• Experience working with automated testing frameworks, including unit, integration, and contract testing.
• Experience supporting CI/CD pipelines and modern software delivery practices.
• Hands-on experience with Docker, Kubernetes, Helm, and cloud-native application deployment.
• Experience working within Agile/Scrum environments.
• Strong communication and collaboration skills within cross-functional international teams.
• English proficiency at B2 level or higher.

Preferred Skills

• Experience working in distributed, international engineering teams.
• Passion for clean architecture, software craftsmanship, and continuous improvement.
• Experience with trunk-based development methodologies.

Location Requirements

• Candidates must be based anywhere within Europe.
• Ability to work remotely while collaborating with international teams across European time zones.
