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 the architecture evolves toward fully AI-native capabilities, including intelligent agents, dynamic user interfaces, and scalable supporting infrastructure.

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

Hybrid work is required, with 3 days from Gdansk or Krakow.

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, retrieval pipelines, and evaluation frameworks such as 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 such as Digital Advisor for Client Assist use cases.
• Build reusable Stencil web components and integrate them into Angular-based applications.
• Contribute across the full stack with balanced frontend and backend ownership.
• Provide 24/7 production support coverage, including 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 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 with LangGraph or equivalent frameworks, LLM integration with OpenAI, Anthropic, or similar tools, memory and 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.

We offer
