UU WALLET, likely a financial or payment services company, is seeking a Backend Engineer to enhance their existing systems and ensure robust, scalable solutions. The emphasis on payment/financial projects and high-concurrency architecture suggests they operate in a transaction-heavy environment. Their preference for candidates with architecture-from-scratch capability indicates potential expansion or modernization of their tech stack. The benefits package (visa sponsorship, housing allowance) suggests they are targeting top-tier international talent, possibly to support global operations or diverse teams.

As an interviewer for UU WALLET, I would prioritize candidates who demonstrate not only technical proficiency but also a deep understanding of financial systems and scalability challenges. Key areas of evaluation would include hands-on experience with Spring technologies, database optimization, and real-world problem-solving in high-concurrency scenarios. Cultural fit is equally important—candidates should exhibit teamwork, knowledge-sharing attitude, and adaptability to fast-paced fintech environments.
