• Reproduce reported defects, create detailed engineering tickets, and validate fixes before closing.
• Maintain and improve internal runbooks, tooling, and admin interfaces to accelerate investigations.

• Strong knowledge of MongoDB, Mongoose ODM, SQL and PostgreSQL.
• Ability to read, debug, and extend a large production codebase you did not write.
