Senior Full Stack Engineer with AI

We are looking for a highly skilled Senior Full Stack Engineer with deep TypeScript and Node.js expertise and hands-on experience building AI-driven, agentic systems. You will help shape next-generation digital experiences as we evolve toward a fully AI-native architecture - spanning intelligent agents, dynamic user interfaces, and the supporting infrastructure required to run them at scale.

This is a client-facing role that requires close collaboration with engineering leadership, balanced work across the frontend and backend, and a passion for delivering production-ready AI experiences. You will contribute to new feature development while ensuring stability and support for live systems.

Please note that hybrid work, 3 days from Gdansk or Krakow, is required.

Responsibilities

• Architect, build, and maintain scalable backend services using Node.js and TypeScript
• Design, extend, and operationalize agentic systems with LangGraph (Node.js) or similar frameworks
• Manage and evolve core agent infrastructure components: memory and context management, session lifecycle management, file spaces, document handling, and retrieval pipelines, evaluation frameworks (e.g., Morpheus or comparable tools)
• Develop AI-powered user experiences, including transitioning native web interfaces toward AI-native patterns, building an AI Center, and creating AI-driven dashboards (e.g., Digital Advisor for Client Assist use cases)
• Build reusable Stencil web components and integrate them into Angular-based applications (e.g., EAA)
• Contribute across the full stack with balanced frontend and backend ownership
• Provide 24/7 production support coverage, including participation in on-call rotations, incident handling, and timely resolution of production issues
• Collaborate directly with client engineering leads and distributed teams to align on technical direction and delivery milestones

Requirements

• 5+ years of professional software development experience, with demonstrated TypeScript expertise and a proven track record across both frontend and backend applications
• Significant backend development experience with Node.js and modern tooling
• Demonstrated experience building full-stack solutions with component-based frontend architectures
• Strong grounding in system design, scalability, performance optimization, and production operations
• Hands-on experience developing AI/agentic systems, including agent orchestration (LangGraph or equivalent frameworks), LLM integration (OpenAI, Anthropic, etc.), memory/context management for conversational or task-oriented agents, and evaluation and validation pipelines for AI models and workflows
• Familiarity with Stencil web components and their integration into Angular applications
• Experience building AI-enabled products or dashboards and understanding emerging AI-native UX patterns
• Comfortable providing production support, including participating in on-call rotations

Nice to have

• Experience with Angular
