Using a structured and engineering-focused approach, you will build robust and maintainable solutions that support both current business needs and the platform’s long-term development.

Working closely with colleagues across technology and business, you will analyze and improve application workflows, strengthen system integrations and drive performance enhancements across the platform. A significant part of the role involves investigating and resolving complex production issues, supporting platform upgrades and identifying opportunities to improve operational stability through monitoring, automation and continuous improvement.

You will play an important role in ensuring the reliability, scalability and performance of the platform while working with technologies such as PostgreSQL, Linux and modern DevOps practices.
