About the role

We’re looking for a Java Developer with an interest in enterprise integrations to join our growing team — or a Junior MuleSoft Developer who wants to grow fast and work on real-world business-critical APIs.

This is a great opportunity to either deepen your MuleSoft skills or transition from Java to a booming integration stack in the API-led world.

You will work in cross-functional teams of architects, project managers, and developers to design, build, and deliver integration solutions for our clients across fintech, e-commerce, and digital platforms.

Responsibilities

• Develop and support enterprise integration solutions using MuleSoft and/or Java.
• Participate in the design of APIs and integration flows based on business requirements.
• Build and maintain API contracts using RAML and RESTful design principles.
• Collaborate with architects and QA engineers to ensure scalable, reliable solutions.
• Configure and manage APIs through the Anypoint Platform.
• Participate in deployment automation, CI/CD pipelines, and environment management.

Requirements

For Java Developers transitioning to MuleSoft

• 1+ years of experience in backend development (Java).
• Understanding of RESTful services, HTTP, JSON/XML.
• Strong OOP and clean code principles.
• Interest in enterprise integration and API-first development.
• Confident spoken and written English (B2 level or higher).

For Junior MuleSoft Developers

• Experience with Anypoint Studio and basic MuleSoft components.
• Knowledge of RAML, DataWeave, and flow design.
• Basic understanding of APIs and integration layers.
• Strong desire to learn and grow in integration architecture.
• Confident spoken and written English (B2 level or higher).

Nice to have (for both)

• Experience with integration platforms such as MuleSoft, Dell Boomi, Oracle ESB, or Apigee.
• Hands-on experience with workflow automation tools: n8n, Make (Integromat), Camunda, or similar.
• Familiarity with CI/CD, Git, and containerization tools like Docker.
• Knowledge of message brokers (Kafka, RabbitMQ) or API security (OAuth2, SSO).
• Interest in building scalable, reusable integration patterns.

We offer

• An exciting project with on-the-edge technology in one of the most dynamic industries.
• A community of professionals to work and have fun together.
• Flexibility in terms of location to work from: we consider applicants from all locations.
• Flexible work schedule.
