• Core Development: Spend a significant portion of your time 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), ensuring strong domain bounded contexts.
• API Excellence: Architect RESTful APIs that prioritize proper HTTP verbs and clean, scalable patterns over legacy RPC styles.
• Team Mentorship & Agile Practices: Utilize a strong understanding of agile and software development practices to motivate the team, engage junior developers, mentor them, and help them grow.
• Strategic Pushback: Demonstrate the ability to confidently push back and say 'no' to power (be it AI or human) when advocating for best practices and architectural integrity.

• Leadership Experience: Proven experience as a Tech Lead or Squad Lead , with a track record of motivating teams and mentoring junior developers.
• Core Stack: Advanced proficiency in Java (Spring Boot) and a solid working knowledge of Angular, with at least 6 years of experience.

• Design Fundamentals: A strong grasp of Object-Oriented Analysis and Design (OOA/OOD), software design patterns, and architectural pattern awareness.
• Domain-Driven Design: Deep understanding and practical experience with strong domain bounded contexts.
• API Knowledge: Deep experience building and consuming RESTful services with a clear understanding of standard API protocols.
• Database Skills: Experience working with relational databases (PostgreSQL, Oracle) and JPA/Hibernate.
• The "Backend-Heavy" Mindset: A passion for server-side logic, performance, and architecture, coupled with good engineering practices.
• 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.
• Cloud & Infra: Experience with cloud platforms (AWS or Azure) and containerization (Docker).
