What you’ll do

• Design, develop and maintain backend services and APIs using Java (Spring ecosystem).

• Deliver high-quality, production-ready code and participate in code reviews and technical design sessions.

• Collaborate closely with business analysts, product stakeholders and international teams to translate requirements into reliable software.

• Own features end-to-end: estimate, implement, test, monitor and operate.

• Improve system performance, scalability and reliability through profiling, optimization and refactoring.

• Promote engineering best practices and knowledge sharing.

• Help define and evolve architecture, coding standards, CI/CD pipelines and observability practices.

• Troubleshoot production incidents, perform root cause analysis and implement long-term fixes.

• Keep up to date with industry trends and propose improvements to tools, frameworks and processes.

What we’re looking for

• Bachelor’s degree or above in Computer Science, Software Engineering or a related field.
