Java Developer

---

Hello and good vibes to everyone reading this!

We’re currently looking for a Middle+ Java Developer to join our team in a full-time collaboration format.

About Us

Mind Studios specializes in mobile and web app development, helping businesses unlock their potential and turn ideas into profitable products. Our key domains include: Real Estate, Logistics, Healthcare, Fitness, and Mental Health.

About the Project

The project is a large-scale digital platform from scratch designed to support the administration of various social benefits in a Western European country through a modular and scalable architecture. The system is structured around two key layers:

• Horizontal functions: Shared core services used across all benefits (e.g., application review, eligibility checks, document management, communication, payment processing, appeals).
• Vertical functions: Individual benefit flows, each with its own set of rules, data requirements, and validation logic.

At the heart of the project is the User Profile, which serves as a central data repository. It collects and stores key personal and household information in a reusable way, allowing different benefit applications to retrieve data without asking the user to re-enter the same information.

Responsibilities

• Clear and effective communication skills, both verbal and written, ability to convey ideas, information, and messages accurately and efficiently.
• Experience in managing diverse project activities (not just coding, but also requirements analysis, preparing estimations).
• Ability to analyze information, assess situations, and make decisions based on sound reasoning and logical evaluation.
• Analytical thinking, problem-solving abilities, and strategic approach to technical challenges.

Requirements

Must-have requirements

• Advanced English, both spoken and written. The developer must communicate confidently with native English-speaking colleagues, participate actively in meetings, clarify requirements, explain technical decisions, and write clear PR descriptions and documentation.
• Experience with Java, including modern Java features; the project currently uses Java 21.
• Strong commercial experience with Spring Boot, Spring Web/MVC, Spring Data JPA, and Hibernate.
• Solid understanding of:
  • Transactions and entity lifecycle
  • Database constraints and data integrity
  • Concurrency and idempotency
  • Date/time handling
  • Validation and error handling
• Strong SQL and relational-database skills. The candidate must be able to investigate existing data, diagnose duplicates and inconsistent states, and design safe schema or query changes.
• Experience maintaining and debugging a large existing codebase or multi-module system, including tracing behavior across services and shared libraries.
• Ability to understand complicated business rules and translate incomplete or changing requirements into predictable implementation.
• Strong REST API design and integration experience, including request/response contracts, backward compatibility, and OpenAPI.
• Experience writing meaningful unit and integration tests with JUnit and Mockito. Regression tests should accompany bug fixes.
• Good Git and pull-request practices: focused changes, readable commits, careful reviews, and constructive technical discussion.
• Demonstrated ownership: independently reproducing problems, finding root causes, considering edge cases, and communicating risks before implementation.
• Willingness to question ambiguous requirements instead of silently making assumptions.
• Ability to work effectively in a distributed, highly communicative team.

Nice-to-have requirements

• Commercial experience with Oracle Database and Oracle-specific SQL behavior.
• Experience with Flyway database migrations.
• Experience with Kafka or another event-driven messaging platform.
• Knowledge of Spring Security, OAuth2/JWT, and Keycloak.
• Experience with Camunda/Zeebe or BPMN-based workflows.
• Experience with caching, particularly Caffeine.
• Familiarity with Azure DevOps, Maven multi-module builds, Sonar, PMD, Checkstyle, and dependency/security upgrades.
• Knowledge of audit logging, personal-data protection, and security-sensitive applications.
