WHAT YOU WILL DO - Spend the majority of your time (approx. 70-80%) designing and implementing robust backend services using Java and Spring Boot; - Build and maintain the supporting Angular frontend, ensuring a seamless connection between the UI and your backend logic; - Lead the transition from traditional database-centric designs toward a domain-driven structure (DDD); - Architect RESTful APIs that prioritize proper HTTP verbs and clean, scalable patterns over legacy RPC styles; - Work within cross-functional squads to deliver high-quality features while maintaining the cohesive and proactive spirit of the team. 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, and a thorough understanding of enterprise-level, high-transactional platforms; - A passion for server-side logic, performance, and architecture; - Upper-intermediate English level. NICE TO HAVES - 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. PERKS AND BENEFITS - Professional growth: Mentorship, TechTalks, and personalized growth roadmaps. - Competitive compensation: USD-based pay with education, fitness, and team activity budgets. - Exciting projects: Modern solutions with Fortune 500 and top product companies. - Flextime: Flexible schedule with remote and office options.
