Are you passionate about technology, understanding how things work, and finding ways to make them better? Are you the kind of person who does not wait to be told what needs fixing, but identifies problems, investigates, and proposes solutions? We are looking for a Backend Engineer with a builder mindset, technical curiosity, and a strong desire to take on responsibility to help us build and improve our product's backend architecture. We are looking for talent, initiative, and a desire to build something great from the inside. Задачи:

Backend architecture: Understand, document, and keep the system architecture up to date. Identify opportunities for improvement, review technical designs, and help define how the different components should evolve. API development and maintenance: Work on existing APIs, improve how they function, identify inefficiencies, and ensure they are reliable, maintainable, and scalable. Performance optimization: Analyze latency, response times, database queries, and potential bottlenecks. Identify the slowest endpoints and propose solutions to improve performance. Monitoring and dashboards: Create and maintain dashboards that make it easy to view system health. Work with metrics such as latency, errors, request volume, database performance, and background processes. Code quality: Review and improve features after they are developed, simplify implementations, remove duplicated code, and reduce technical debt. Add tests to protect critical product flows. Reliability and incident resolution: Monitor production errors, work with tools such as Sentry, investigate problems,



and take responsibility for ensuring incidents are resolved and do not happen again. Security: Identify potential vulnerabilities, review permissions and authorizations, ensure data isolation between customers, and maintain good security practices. Infrastructure and optimization: Oversee the operation and costs of infrastructure, databases, and related services. Identify opportunities to improve technical and economic efficiency. Continuous improvement: Proactively identify problems and opportunities for improvement. Do not wait to receive tasks: propose what to change, why to do it, and how to measure whether it worked.
