Overview

We are hiring a Software Engineer to join an enterprise engineering team within a large, structured corporate environment. This role supports the design, development, and enhancement of internal systems that are critical to business operations.

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.

• Build and maintain frontend components using TypeScript, JavaScript, and React
• Work with MS SQL Server or PostgreSQL databases to support application functionality
• Write clean, maintainable, and testable code aligned with enterprise engineering standards
• Participate in code reviews and collaborative development activities, including pair programming
• Independently troubleshoot issues and implement robust solutions
• Complete coding assignments and project tasks by strictly following documented requirements

Must‑Have Experience

• Minimum 3+ years proven experience developing applications with Java and Kotlin in a corporate or enterprise setting
• Full stack development experience, including React, TypeScript, and JavaScript
• Hands‑on experience with relational databases such as MS SQL Server or PostgreSQL

• Ability to work independently and take ownership of assigned work
• Experience delivering working code under minimal supervision

We regret to inform that only shortlisted candidates will be notified.
