This role is responsible for ongoing support, enhancement, and maintenance of both current and legacy applications, websites, and supporting infrastructure using Microsoft-based technologies.

In addition to legacy support, this role will play a key role in modernizing and consolidating existing GST software applications into a unified, modular platform built on a modern technology stack. The engineer will help evolve current systems toward a configuration-driven model that allows functionality to be enabled or disabled based on client needs while maintaining continuity of service for existing customers.

The ideal candidate is a senior-level engineer who is comfortable working across the full software lifecycle, balancing operational support responsibilities with forward-looking modernization and architectural improvement.

Key Responsibilities

• Provide application support, troubleshooting, and user training for legacy systems to provide continuity of service for mission-critical applications, such as responding to incidents, conducting root cause analysis, identifying application issues and/or data fixes, and working with end-users to address application questions and issues.
• Maintain and update reports associated with GST applications, using tools such as Crystal Reports.
• Develop and maintain databases, including design, implementation, optimization, and administration.
• Administer and support websites, including permissions, ownership, indexing services, logs, usage statistics, and content management (website platforms include both ASP.NET and WYSIWYG editors such as Wix).
• Produce and maintain comprehensive technical documentation such as requirements, design specifications, and user guides.
• Identify, document, and prioritize technical debt and make trade‑off recommendations to stakeholders.
• Design, develop, enhance, and maintain Windows‑based and web applications using Microsoft development technologies.
• Provide mentoring and direction to junior software developers.
• Provide Windows desktop, server, and printer support as required to end users.

Required Qualifications

• Bachelor’s degree in Computer Engineering, Computer Science, or a related technical field (or equivalent experience).
• Proven experience developing applications using C#, ASP.NET, VB6, and VB.NET.
• Strong experience with Microsoft SQL Server and Microsoft Access.
• Experience working with legacy applications, including report development and maintenance using Crystal Reports.
• Experience with secure coding and development practices.
• Experience administering and supporting IIS‑hosted applications and services.
• Working knowledge of virtualized environments and Virtual Machines (VMs).
• Proficiency using SQL Server Management Studio (SSMS) for querying, troubleshooting, and database administration.
• Experience using GitHub for source control, collaboration, and version management.
• Working knowledge of Windows system administration.
• Ability to work independently and collaboratively in a client-facing, government-supported environment.
• Strong analytical, documentation, and communication skills.
• Demonstrated ability to communicate complex technical concepts clearly to non-technical users, including government and public-sector stakeholders.

Security & Eligibility Requirements

• Ability to successfully pass a government background investigation.
• Must meet eligibility requirements associated with government-supported projects.
