• Write clean, testable, production-grade Java code following Clean Architecture and SOLID principles
• Enforce engineering best practices: code reviews, architecture standards, CI/CD discipline
• Collaborate in an Agile environment with clearly defined monthly delivery milestones
• Take responsibility for system reliability, scalability, performance, and security
• Mentor other engineers and raise the overall engineering bar
• Work closely with product and business to ship real business outcomes, not just features.
