ABOUT THE ROLE
We are looking for a Senior Backend Engineer to maintain, improve, and expand an internal Node.js platform that has evolved from an API proxy into a broader operational system supporting multiple business areas. You will build and maintain backend services and API integrations, improve application reliability and scalability, troubleshoot production issues, and provide React frontend support when needed.

- Improve application reliability, scalability, and maintainability;
- Investigate production issues, reduce downtime risk, and support operational stability;
- Work with existing codebases, identify improvement areas, and refactor where needed;
- Contribute to frontend web tasks using React when backend work has lower demand or when product priorities require support;
- Collaborate with product, engineering, and business stakeholders to understand requirements and deliver practical solutions;
- Own technical tasks from analysis through implementation, testing, and delivery;
- Self-test work thoroughly before QA and proactively identify edge cases, bugs, and performance risks;
- Document key technical decisions, setup steps, and implementation details when needed;
- Work with Git, deployment workflows, and development best practices to support reliable releases.
