You will work across the full software development lifecycle, taking ownership of backend-heavy solutions that require strong logical thinking, clean design, and the ability to anticipate real-world usage patterns. While the role includes exposure to frontend technologies, success in this position is driven by backend strength, problem-solving ability, and independence.

• Work with MS SQL Server or PostgreSQL databases to support application functionality
• Write clean, maintainable, and testable code aligned with enterprise engineering standards
