They work closely with end users and developers to resolve technical issues, ensure applications run smoothly, and often manage deployments and updates.

Job description

TransCore (TRN), a subsidiary of ST Engineering, is seeking a full-time .NET Application Support Engineer to join our team in Ashburn, Virginia.  

Job Summary:

We are seeking a skilled and solutions-oriented .NET Application Support Engineer to ensure the stability, reliability, and performance of our enterprise applications built on the Microsoft stack. In this role, you will bridge the gap between software development and systems operations. You won’t just be waiting for tickets; you will actively dive into existing C#/.NET codebases to diagnose failures, manage and tune IIS web server environments, and write robust automation scripts to eliminate repetitive manual tasks.

Other locations of consideration are Pennsylvania and New Jersey. 

The ideal candidate possesses a "systems thinker" mindset—someone who enjoys the puzzle of root-cause analysis and loves using scripting to automate deployments and infrastructure setups.

Essential Duties and Responsibilities include but not limited to:  

  • Incident Management & Troubleshooting: Own L2/L3 technical support for high-availability .NET applications, APIs, and Windows Services. Diagnose runtime errors, application crashes, and performance bottlenecks.
  • Code-Level Debugging: Analyze and debug C# source code to identify defects, trace execution flows, and deliver root-cause analysis (RCA) to the core development teams.
  • Environment & Infrastructure Setup: Configure, maintain, and optimize IIS (Internet Information Services) web servers, application pools, and environment variables across staging and production servers.
  • Scripting & Automation: Develop and maintain a library of PowerShell scripts to automate routine operations, application deployments, system health checks, and data fixes.
  • Database Maintenance: Troubleshoot application data faults by writing and optimizing complex T-SQL queries, analyzing stored procedures, and resolving SQL Server bottlenecks.
  • Monitoring & Documentation: Proactively monitor application health logs (Event Viewer, Azure Monitor, or similar) and maintain detailed technical documentation for known errors, environment configurations, and recovery procedures.

Required Technical Skills:

  • The .NET Ecosystem: 3+ years of experience supporting or developing applications using .NET Core, .NET Framework (4.x+), ASP.NET MVC, and Web API.
  • Scripting: Strong proficiency in PowerShell (preferred) for systems automation and configuration management.
  • Web Servers: Solid understanding of IIS architecture, including site bindings, SSL certificate management, and app pool optimization.
  • Databases: Proficient with Microsoft SQL Server, including writing T-SQL queries, joins, and understanding database indexing.
  • Diagnostic Tools: Experience utilizing windows diagnostic utilities, Event Viewer, log parsers (Serilog/Log4Net), or APM tools to isolate infrastructure vs. code issues.

Preferred Qualifications:

  • Three to five years of previous experience.
  • Experience with cloud infrastructure platforms (Azure, Google, AWS).
  • Familiarity with containerization tools like Docker.
  • Experience working with CI/CD tools (Azure DevOps, Jenkins, or GitHub Actions).
  • Experience with ticketing systems like Jira.

Education: Bachelor’s degree from an accredited educational institution or equivalent combination of education and experience.

Soft Skills Desired:

  • The "Detective" Mindset: A persistent, systematic approach to troubleshooting rather than guessing or applying superficial fixes.
  • Strong Communicator: Ability to clearly explain complex technical issues to both non-technical stakeholders and core software developers.
  • Autonomy: Comfortable balancing multiple shifting priorities in a fast-paced production environment.

TransCore provides equal employment opportunities (EEO) to all employees and applicants for employment without regard to race, color, religion, gender, sexual orientation, gender identity or expression, national origin, age, disability, genetic information, marital status, amnesty, or status as a covered veteran in accordance with applicable federal, state and local laws.
