We are looking for a Senior Fullstack Developer with strong experience in Node.js and React.js to build scalable, real-time web applications and AI-powered products.
This role is ideal for an AI-native engineer who actively uses AI to improve the way they design, develop, debug, and deliver software - not simply delegate coding to AI.
You will work closely with international clients and internal teams, so strong English communication, ownership, and agency mindset are essential.
What You’ll Do:
Design, develop, and maintain scalable fullstack applications using Node.js and React.js.
Build and integrate real-time features and services using WebSocket.
Work across both frontend and backend, taking ownership of features from concept to production.
Design APIs, system architecture, and integrations with third-party services.
Leverage AI orchestration and AI-native development workflows to improve engineering productivity and product delivery.
Collaborate directly with international clients to understand requirements, discuss technical solutions, and provide clear updates.
Identify technical challenges proactively and propose practical solutions.
Work independently with a high level of ownership while collaborating effectively with distributed teams.
Review code, improve system quality, and contribute to technical decisions and best practices.
What you bring
What We’re Looking For:
7+ years of professional experience in full-stack software development.
Strong hands-on experience with: Node.js, React.js, JavaScript / TypeScript
Solid experience building real-time applications with WebSockets.
Strong understanding of backend architecture, APIs, databases, and scalable web applications.
Solid experience with AI-native development and AI orchestration - such as integrating LLMs, AI agents, workflows, or orchestration frameworks into software products.
Fluent English with strong verbal and written communication skills (C1/Ielts 7.0)
Comfortable working directly with international clients in an agency/service environment.
Strong ownership and agency mindset - able to understand problems, make decisions, communicate proactively, and drive work forward without constant supervision.
Comfortable working remotely and independently across different teams and time zones.
Nice to Have:
Experience with AI agents, LLM applications, RAG, or agentic workflows.
Experience with event-driven or distributed systems.
Experience with WebRTC or other real-time communication technologies.
Experience working with international clients or software agencies.
Experience designing and evolving systems at scale.
What we offer
What You’ll Get:
Work on modern AI-native and real-time products.
Direct collaboration with international clients.
High level of ownership and autonomy.
Opportunity to work with experienced engineers and modern technologies.
A collaborative environment where initiative, clear communication, and practical problem-solving are highly valued.
