Senior Developer

Keith Zars Pools (KZP) is hiring a Senior Developer. KZP runs its business on a homegrown line-of-business application backed by SQL Server, alongside a fleet of internal desktop and reporting applications, a growing set of internal web applications, and a mobile app. Our web and mobile front-end work spans Vue, Framework7, and Flutter. We manage our Windows desktops and servers with PowerShell. We're bringing development in-house and consolidating this work into a single senior engineering role reporting to the IT Director. We hire for coding ability and judgment first - the stack is learnable - but Windows-centric development is preferred, and Windows Server and desktop management are a plus. We use modern development tooling, including AI-assisted tools, day to day. What you'll do

• Pair with the IT Director on the modernization roadmap - write code, review code, and own pieces of it as trust is earned.
• Maintain and triage our legacy VB.NET desktop application fleet. Keep it running, and pull pieces forward into modern web replacements as they come online.
• Build and maintain our internal web and mobile applications.
• Own integration work between SQL Server, accounting systems, supplier systems, and internal tooling.
• Provide emergency support for the production database application when it's needed.
• Backstop desktop support during high-volume weeks - new-hire setups, VPN, Microsoft 365 administration, printers.
• Manage vendor escalations with clear, written communication.

Do you have experience in Windows?, * Comfortable reading and writing across the Microsoft language set - C#, T-SQL, PowerShell, and VB.NET - with real fluency in at least one.

• You read code confidently, including in unfamiliar codebases, and spot plausible-looking-but-wrong output before it reaches production.
• You turn vague business asks into concrete, written plans, break them into tractable steps, and ship without hand-holding.

Platform fluency A working grounding across several of these, with real depth in some:

• Active Directory and Microsoft 365 administration
• IIS on Windows Server
• SQL Server administration
• Azure / Entra ID and certificate management

Nice to have

• Experience modernizing legacy desktop and database codebases
• PowerShell automation against business productivity systems
• Experience integrating systems via APIs
• Open-source contributions or a real personal project portfolio
