Position Overview

We are looking for a Full Stack Engineer with experience building applications across platforms—from mobile to browser to PC.

You’ll work on:

  • Building secure, intelligent, cross-platform assistant interfaces using React Native and modern web technologies
  • Integrating OpenInfer’s runtime into applications on mobile and PC (think: assistant apps, browser extensions, system overlays)
  • Developing local-first UIs that coordinate with AI workflows and memory systems
  • Collaborating with AI infra and systems engineers to close the loop between model reasoning and user experience
  • Prototyping and shipping fast—especially with Vibe coding or similar tools

Must-have experience:

  • 3+ years building full stack applications, ideally in production environments
  • Strong knowledge of React Native, JavaScript/TypeScript, and modern browser APIs
  • Experience shipping cross-platform apps (mobile and desktop)
  • Familiarity with vibe coding workflows and rapid UI development
  • Comfort working in a fast-moving startup environment with ambiguity and evolving requirements

Bonus experience

  • Exposure to Rust or C++
  • Understanding of LLM architectures or AI model deployment
  • Experience integrating with local runtimes or edge compute platforms
  • Contributions to open source projects or past AI-related applications

  • Medical, Dental, and Vision benefits
  • Flexible Paid Time Off
  • Parental Leave
  • 401(k) Plan with company matching
  • Snacks and coffee to keep you energized

These benefits are further detailed in OpenInfer policies and are subject to change at any time, consistent with the terms of any applicable compensation or benefits plans.
