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.
- 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
- 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
- Experience with Angular
