●     Ownership mindset: You act like a founder-even if you're not one

●     Technical depth: You’ve built things from scratch and understand what’s under the hood

●     Product intuition: You don’t just write code—you ask if it solves the user’s problem

●     Startup muscle: You’re scrappy, resourceful, and don’t need layers of process

●     Bias for action: You unblock yourself and others. You push code and push thinking

Humility and curiosity

: You challenge ideas, accept better ones, and never stop learning

💡 Nice-to-Have

●     Experience with NLP, speech interfaces, or audio processing

Why Join Nexa?

●     Work directly with founders on a product that pushes boundaries in voice AI
