Senior Full-Stack Engineer (Laravel, React)

We are an established media and publishing organization building and operating our own software platform, with independent Laravel and React applications plugged into a unified dashboard that supports advertising, CRM, and publishing operations. We are bringing several products to market as a commercial multi-tenant SaaS suite, and this role sits at the center of that transition. Our team is small but technically broad, which gives us high ownership, direct access to decision makers, and very little bureaucracy. The engagement starts as a 90-day contract at approximately 30 hours per week during Central Time business hours, with conversion to full-time based on performance. We offer a hybrid remote setup in Plano, TX, along with health, dental, vision, PTO, 401k, remote flexibility, and a compensation range of $50.00 to $80.00 per hour.
