Fluxon Tech Stack

Custom software studio for web, mobile, and data platforms

Software Development San Francisco, California 201–500 employees Privately Held

Fluxon is a product development studio operating across North America, Europe, and Asia with a polyglot tech foundation (TypeScript, Java, Python, Go, Rust, Rails) spanning frontend (React, Next.js, Angular), backend (Spring, FastAPI, Django), mobile (Swift, Kotlin, Expo), and cloud infrastructure (AWS, GCP, Azure). The hiring mix is heavily weighted toward senior and staff engineers relative to product and design roles—a staffing pattern typical of a high-touch services org scaling delivery capacity rather than building a scaled product.
