Job Description

We are looking for a highly skilled Full Stack JavaScript Engineer to help us build a cutting-edge AI-powered automation platform. This system will act as a smart assistant, capable of continuously monitoring and processing various data streams, providing real-time assistance, and automating key workflows.

The ideal candidate has experience developing scalable AI-driven web applications, integrating real-time data processing, and working with LLMs (e.g., OpenAI API). This role involves architecting a secure, self-hosted AI system that leverages microservices, voice interaction, OCR, NLP, and multimodal AI to provide users with a truly intelligent assistant.

As part of our hiring process, we will assign a short test task to evaluate technical proficiency. Candidates who successfully complete this will be considered for a long-term role on our team.

Key Responsibilities:

- Develop and scale an AI-driven automation assistant using React.js, Node.js (Express), and Cursor AI.

- Build a real-time web application with seamless voice, text, and multimodal AI interaction.

- Integrate with third-party APIs (email, messaging, calendar, etc.) to create a context-aware AI assistant.

- Optimize system performance, scalability, and security for enterprise-grade deployment.

- Collaborate with AI/ML engineers, DevOps, and backend developers to ensure a seamless user experience.

Primary Skills & Requirements:

- React.js & Tailwind CSS – Experience in modern UI development with component-driven architecture.

- Node.js (Express) & RESTful APIs – Proficiency in backend development and handling real-time data streams.

- Cursor AI & AI/LLM Integration – Familiarity with Cursor AI for AI-assisted development and experience with OpenAI API or similar.

- Microservices & Scalable Architecture – Ability to design distributed systems with secure API communication.

- Data Handling & Real-Time Processing – Experience working with event-driven architectures, WebSockets, and streaming data.

Why Join Us?

- Work on next-gen AI automation with a highly skilled team.

- Opportunity to build a truly intelligent, context-aware assistant that goes beyond basic chatbots.

- Long-term full-time role for the right candidate.

- Competitive compensation & a chance to work on high-impact AI projects.

How to Apply:

- Submit your resume and GitHub/portfolio showcasing relevant work.

- Briefly describe your experience with AI assistants, real-time data processing, and automation.

- Complete a short test task (a lightweight AI chat interface) to demonstrate technical skills.
