Senior Full Stack Engineer

Senior Full Stack Engineer

We are looking for a Senior Full Stack Developer to build backend services with Java and Spring Boot, support the Angular frontend, and help move the architecture toward domain-driven design.

The mandatory requirements are strong transactional SQL expertise with Oracle or PostgreSQL on high-transaction enterprise platforms, 4+ years with Java (Spring Boot) and Angular, JPA/Hibernate, RESTful API design, object-oriented design and design patterns, and an upper-intermediate English level.

Must haves

• Core Stack: Advanced proficiency in Java (Spring Boot) and a solid working knowledge of Angular, of at least 4 years.
• Design Fundamentals: A strong grasp of Object-Oriented Design (OOD) and software design patterns.
• API Knowledge: Deep experience building and consuming RESTful services with a clear understanding of standard API protocols.
• Database & Advanced SQL (Strict Rejection Criteria): 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.
• The "Backend-Heavy" Mindset: 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).
• Domain

Experience

• 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
