Frontend Engineer

Infatica.io is a global provider of proxy and DaaS solutions. We're building our own high-load web scraping platform: an API where you can submit any URL and receive clean HTML or structured JSON output, without worrying about proxies, CAPTCHAs, or anti-bot systems.

The platform will support both cloud deployment and on-premises deployment in client infrastructure (on-prem, Kubernetes).

• Develop AI-powered UIs (chat, generators, assistants) and ensure real-time or streaming interactions with smooth UX.
• Integrate AI APIs (OpenAI, Claude, Codex, etc.) into the product, with robust error handling, retries, and graceful fallbacks.
• Leverage AI coding tools and agent-like workflows to accelerate development and enable AI-assisted features.
