Full Stack Engineer

Role Overview We are hiring a frontend-leaning Full Stack Engineer to own production features across our customer web application, company website, internal admin tools, and Android kiosk/device software. You will partner closely with the Technical Lead, take day-to-day ownership of frontend and device-facing delivery, and contribute to the backend services that connect physical machines to the platform. Your initial priority will be the company website rebuild from architecture decision through launch: reusable components, CMS and content migration, analytics, technical SEO, redirects, performance, release validation, and post-launch monitoring. Over time, the role will focus primarily on product and admin frontends, kiosk/device-screen experiences, and machine-related service integration. This is a hands-on software role, not an electrical or mechanical engineering position. You are not expected to be an expert in every technology below; we value depth in React and TypeScript, strong full-stack fundamentals, practical troubleshooting, and the ability to learn unfamiliar systems independently.
