.NET Support/Development Engineer (ONSITE)

About the role

A seasoned application support and development engineer is needed to maintain, enhance, and modernize a diverse application portfolio spanning legacy systems, Microsoft technologies, SharePoint, Power Platform, and SQL Server.

Responsibilities

• Triage and resolve production incidents across the application portfolio, ranging from legacy to modern technology stacks, with clear root-cause writeups and durable fixes.
• Deliver enhancements and feature work against existing .NET, ASP.NET, and VB.NET codebases while preserving behavioral fidelity and improving maintainability.
• Quickly learn the functionality, architecture, and design intent of existing systems in order to troubleshoot effectively and deliver changes that align with established patterns.
• Build, maintain, and extend solutions across SharePoint Online, SharePoint on-premises, and the Microsoft Power Platform, with a strong focus on Power Apps and Power Automate.
• Maintain and optimize SQL Server databases, including stored procedures, indexes, job schedules, performance diagnostics, and schema changes as code.
• Partner with business analysts and client stakeholders to translate support requests and enhancement needs into well-scoped, testable change items.
• Apply AI-assisted workflows to root-cause analysis, patch drafting, regression test generation, and runbook documentation, while following team standards for review and verification.
• Own post-incident reviews and turn systemic findings into backlog items that reduce recurrence.

Requirements

• 8+ years of professional software engineering experience, including meaningful production support ownership and real accountability during incidents.
• Strong .NET, .NET Core, ASP.NET, C#, and VB.NET experience across Web Forms and MVC/Core applications.
• Confidence reading, debugging, and extending legacy codebases without defaulting to unnecessary rewrites.
• Ability to quickly understand existing system functionality, design, dependencies, and business workflows, then apply that knowledge to support, enhancement, and defect-resolution work.
• Practical understanding of IIS hosting, application configuration, deployment considerations, and application lifecycle behavior.
• Genuine comfort with VB.NET as a first-class requirement, including reading, debugging, and modifying existing code without friction.
• Solid SQL Server and T-SQL depth, including stored procedures, triggers, complex queries, execution plan analysis, index strategy, concurrency and locking, and schema migration practices.
• Hands-on SharePoint Online and/or SharePoint on-premises experience, including site and list administration.
• Production delivery experience with Power Apps, including canvas and model-driven apps, and Power Automate flows.
• A structured support mindset: disciplined incident triage, root-cause analysis, change management, testing, documentation, communication, and composure under production pressure.
• Daily, beyond-autocomplete proficiency with GitHub Copilot agent mode or comparable AI-assisted development tools, applied to investigation, patch generation, test scaffolding, and runbook authorship.
• Strong judgment in verifying AI-generated output before shipping code, documentation, or operational guidance.

Qualifications

• Exposure to electric utility operations, IT/OT operations, or regulated-industry software environments.
• Power BI familiarity.
• Prior exposure to OpenROAD 4GL or Actian Ingres Database, even at a passing familiarity level.
• Curiosity and composure when learning unfamiliar legacy stacks, tracing bugs through them, and delivering reliable fixes.
