Principal Software Engineer at Point of Rental Software in Fort Worth, Texas

Job description

• Position at Point of Rental Software
• Our software runs rental operations on six continents, so the systems you touch here have real weight behind them. This role gives you a rare combination: a modernization effort big enough to be genuinely interesting, the autonomy to decide how it gets done, and a team small enough that your technical judgment actually shapes the product. If you want to be the person who decides how a legacy platform becomes a modern one, this is that job.

Responsibilities

• Own the technical direction of the WinForms-to-web modernization: decide what gets rewritten, what gets wrapped, what gets left alone, and in what order, then make those calls stick
• Build and ship full stack, from Angular front ends through C#/.NET services to SQL Server. This is a hands-on role, not an architecture-diagram role
• Work confidently in large, long-lived legacy code, and make it safer and better as you go rather than working around it
• Use AI coding tools as a daily part of how you ship, including getting oriented in unfamiliar code fast and accelerating the modernization work
• Set the bar for how the team uses AI tooling: shared standards, context, and a clear view of where we deliberately don't rely on it
• Design and hand-write the complex SQL behind features that have to perform at enterprise scale
• Raise the level of the engineers around you through design review, pairing, and mentorship
• Operate with real autonomy on ambiguous problems, and bring the team along with a clear written case for your approach
• Partner with Product to turn business problems into technical plans that survive contact with reality

Requirements

• 8+ years as a professional software engineer, with several of those years owning significant systems end to end
• 5+ years with C# and .NET, building production applications
• 5+ years building production applications in a component-based SPA framework, Angular strongly preferred. We're on Angular 19 with Nx, and you'll need to get productive there quickly
• 5+ years with SQL Server or another major RDBMS, including writing complex SQL by hand
• A track record of setting technical direction that other engineers actually followed, and of being right often enough that they kept following it
• Comfort reading and safely modifying large legacy code. You don't need to love it, but you do need to be undaunted by it
• Fluent, everyday use of AI coding assistants (GitHub Copilot, Cursor, Claude Code, or similar) as part of your real workflow, not as an experiment
• Sound judgment about where AI helps and where it doesn't. You review what it produces, catch what it gets wrong, and don't ship code you can't explain
• Real depth in algorithms, data structures, and design patterns, whether that came from a CS/Math/CE degree or from doing the work
• Preferred: RESTful API development, porting desktop functionality to the web, microservices/serverless, Azure DevOps, Scrum with short sprints, and automated testing at multiple levels (Jest, NUnit).
