About Winixx

Winixx Inc. is a New York-based technology holding company operating a portfolio of over 35 SaaS platforms across freight, fleet management, financial infrastructure, and market intelligence. We are now building WinixxOS — a distinctive, AOSP-based operating system powering a full lineup of consumer hardware including phones, tablets, smartwatches, POS devices, and gaming consoles. Founded with a mission to modernize fragmented and underserved industries, Winixx builds technology that removes inefficiencies, creates transparency, and puts more value in the hands of the people doing the actual work.

This is early-stage, high-ownership platform engineering — you would be shaping foundational decisions for a new OS, not implementing someone else's spec.
