Job Overview
If you are a developer who enjoys both coding and solving real-world production issues, this Software Engineer – Application Support (.NET / SQL) role is a strong career opportunity. This position focuses on supporting and improving enterprise logistics applications in a fast-paced, SLA-driven environment.
Unlike traditional developer roles that focus only on building new features, this job combines production support (50%) and development (50%). That means you will not only fix issues in live systems but also implement improvements and enhancements. This type of experience is highly valuable because it teaches you how real systems behave in production.
You will work on critical applications used in logistics operations, where system stability and performance are very important. This role is ideal for developers who want to improve their debugging skills, understand system architecture, and gain experience with enterprise-level workflows.
For Sri Lankan developers, this is a great opportunity to gain experience in support + development roles, which are highly demanded in global IT companies.
About the Role
This role focuses on application support engineering, which involves maintaining and improving live systems used by businesses.
You will work in an SLA (Service Level Agreement) environment, meaning issues must be resolved within specific time limits. This helps you develop speed, accuracy, and responsibility in your work.
The role requires strong technical skills in .NET, C#, and SQL, along with the ability to debug issues in production systems. You will also interact with business users and technical teams to ensure smooth operations.
You will handle around 10–12 support tickets per day, making this a dynamic and active role. There is also an on-call rotation (once per month), where you may need to respond to critical issues.
Key Responsibilities
As a Software Engineer – Application Support, your work will involve both technical problem-solving and development tasks.
- You will provide L2/L3 production support for enterprise applications. This means handling complex issues that require deeper technical knowledge.
- You will investigate and resolve production incidents. This involves analyzing logs, identifying root causes, and fixing problems quickly.
- Debugging is a major part of your role. You will work with .NET and SQL to find and fix issues in the code and database.
- You will implement bug fixes and minor enhancements. This helps improve system performance and user experience.
- Root cause analysis is another key responsibility. You will identify recurring issues and find long-term solutions.
- You will manage incidents using ITIL-based processes and tools like ServiceNow. This ensures structured and efficient handling of issues.
- Tracking tasks using Azure DevOps is also part of your work. This helps manage development and support activities.
- You will communicate with both technical teams and business users. Clear communication is important to understand problems and provide solutions.
- You will also participate in major incident handling and on-call rotations, ensuring system stability at all times.
