Full-Stack Developer (Node.js + React)

100% Remote, working time zone GMT+4. You will work in an international team, so knowledge of English B2 or above is necessary.

Vallettasoftware - custom mobile/web software developer in the US and Europe. Our teams implement IT projects of varying complexity, including website and mobile app development, enterprise systems, and solutions based on artificial intelligence and machine learning (AI/ML).

We are looking for a strong Full-Stack Developer to boost the client's team with deep expertise in React and Node.js, solid hands-on experience in coding and system architecture, who actively uses AI agents in daily development — for designing, writing, optimizing, and testing code through well-structured prompts.

We are looking for someone who thinks systemically, knows how to build and manage context for AI tools, and can turn them into real, measurable productivity rather than treating them as simple assistants.

Key Responsibilities

• Develop and maintain applications using Node.js (NestJS / Express) and React (including Next.js).
• Actively leverage AI agents to accelerate and automate development tasks: code generation, error analysis, and module design.
• Design system architecture and build environments where AI can effectively support the team (context management, memory, prompts, action chains).
• Develop and evolve internal AI tools, integrating with LLM APIs (OpenAI, Claude, Mistral, Ollama, etc.) as needed.
• Optimize and refactor code, conduct code reviews, and implement engineering best practices.
