A stable, established SaaS company in the logistics/transportation technology space is hiring a Senior Full Stack Engineer to help lead a major platform consolidation unifying several large-scale web applications into one modern platform processing millions of data points daily.

This is a hands-on architecture role, not just feature work. You'll start front-end-heavy and grow toward a genuine 50/50 full-stack split over the next few years as you take on more of the C#/.NET back end, owning real decisions around state management, performant architecture, and systems design along the way.

What you'll bring:

• 5+ years building modern front-end applications, with real hands-on back-end experience as well
• Senior-level, subject-matter-expert depth in React, Angular, Vue, or Svelte, with genuine willingness to work primarily in React going forward
• Real command of state management, able to reason through architecture, not just use a library
• Strong systems design instincts and a track record of building performant, scalable architecture
• Genuine openness to growing into C#/.NET on the back end over time (Node.js, Go, or similar backend experience today is fine to start)
• Experience working in large, shared codebases

Nice to have:

• Specific React experience
• Existing C#/.NET experience
• Experience building or consuming REST APIs
