**🚀 React Native + TypeScript Developer (Equity-Based)About UsWe’re an early-stage startup building PanPalz — a new kind of social platform.**

We spend hours connected to everyone—and still feel like we’re talking to no one. When the noise fades, most of us just want one person who gets it. That’s where PanPalz comes in. Real, 1-on-1 conversations—where your voice matters and your privacy is never up for sale. We’re not here to replace other platforms. We’re here for the moments they weren’t built for: the quiet ones, the curious ones, the real ones.

**This role:**

*   Part-time (~20 hrs/week)
*   Equity-based while we raise seed funding
*   Potential to transition into a full-time salaried position
*   Work directly with the founding team to build and iterate on the mobile app

If you’re excited about building from scratch, shaping the tech, and leaving your mark—we’d love to hear from you.
