Job description

About the role

We are looking for a Full Stack Engineer to build backend services with Java and Spring Boot, supported by an Angular frontend, for an enterprise platform.

The mandatory requirements are 4+ years of experience with Java, Spring Boot, and Angular, transactional SQL expertise with Oracle or PostgreSQL, and an upper-intermediate English level. Experience with spec-driven development is a plus.

Must haves

• Advanced proficiency in Java (Spring Boot) and a solid working knowledge of Angular, of at least 4 years
• A strong grasp of Object-Oriented Design (OOD) and software design patterns.
• Deep experience building and consuming RESTful services with a clear understanding of standard API protocols.
• Experience working with relational databases (PostgreSQL, Oracle) and JPA/Hibernate. Candidates must have robust transactional database experience (Oracle, Postgres), strong SQL skills to navigate and optimize very complex SQL in KALC, and a thorough understanding of enterprise-level, high-transactional platforms. Lacking this specific database proficiency will be a direct reason for rejection
• A passion for server-side logic, performance, and architecture.
• Upper-intermediate English level.

Nice to haves

• Highly desirable: Experience working with spec-driven development or related (AI-Driven Software Development Life Cycle)
• Previous experience in the Loyalty or Fintech sectors.
• Experience with cloud platforms (AWS or Azure) and containerization (Docker).
• Knowledge of CI/CD pipelines (Jenkins, GitLab CI).
• Experience refactoring legacy structures into modern, domain-driven architectures.

What you will do

• Core Development: Spend the majority of your time (approx. 70-80%) designing and implementing robust backend services using Java and Spring Boot.
• Frontend Integration: Build and maintain the supporting Angular frontend, ensuring a seamless connection between the UI and your backend logic.
• Modernizing Architecture: Lead the transition from traditional database-centric designs toward a domain-driven structure (DDD).
• API Excellence: Architect RESTful APIs that prioritize proper HTTP verbs and clean, scalable patterns over legacy RPC styles.
• Collaboration: Work within cross-functional squads to deliver high-quality features while maintaining the "cohesive and proactive" spirit of the team.

Perks

• Growth without limits: build your skills through mentorship, internal TechTalks, challenging projects, and a dedicated annual learning budget
• Competitive compensation: get recognition that reflects your skills and impact, with regular performance and compensation reviews
• Flexibility: work 100% remotely with flexible hours that support focus, autonomy, and a healthy work rhythm
• Meaningful, modern projects: build impactful products using modern technologies alongside global teams and leading brands
• Collaborative culture: join a supportive environment with zero micromanagement where ideas are welcomed and contributions are recognized
• Well-being & support: access local well-being programs and people-focused support tailored to your location
