Senior Frontend Engineer

We are building VertoX, an AI-powered real-time voice translation platform that translates speech while preserving the user's original voice, tone, and emotions. The company is incorporated in the USA (Delaware), and we are preparing for a live launch. We need a strong Senior Frontend Engineer to join the core team, take full ownership of our Web/Desktop apps, and grow with us long-term. This is a founding team role, not a temporary contract. You will work directly with: Founder, AI/ML Engineer, and Senior Backend Developer. What you will do: Architect and build production-grade Web (React / Next.js) and Desktop (Electron or Tauri) apps. Implement latency-sensitive, real-time features: live audio, translation UI, and WebSockets/streaming data. Optimize performance for low-latency interactions across Windows, macOS, and Linux. Collaborate closely with Backend & AI/ML engineers on core product UX. What we're looking for: 7+ years of professional frontend experience with deep knowledge of TypeScript, React, and Next.js. Strong production experience with real-time applications (WebSockets, async data flows, state management like Zustand/Redux). Experience building and deploying desktop apps (Electron or Tauri). Solid understanding of auth systems (JWT, OAuth) and clean architectural patterns. Big plus: Experience with WebRTC, audio streaming, or AI products. What we offer: Equity: 1% (become a part-owner of VertoX; salary discussed post-funding). High ownership, zero bureaucracy, and a direct impact on a global AI product. Commitment: This is an early-stage startup. We expect dedication, high responsibility, and long-term involvement. If you are not ready to fully commit, please do not apply.
