Summary
A middle-level full stack developer (TypeScript/Node.js) builds AI-powered applications at Viseven, a MarTech provider for pharma companies: developing AI agents with LangChain/LangGraph/LangSmith, integrating LLMs with external tools and enterprise systems, and building RAG retrieval layers (hybrid/vector search), with guidance from senior engineers.
We are looking for a Middle Full Stack Developer to join our team and contribute to the development of AI-powered solutions.
In this role, you’ll work on well-defined tasks of moderate complexity, collaborating with experienced engineers and receiving guidance and code reviews. You’ll contribute to larger AI initiatives and help build reliable, scalable applications powered by modern Generative AI technologies.

- Integrate LLMs with external tools, APIs, knowledge sources, and enterprise systems.
- Contribute to building retrieval layers (e.g., hybrid search, vector search, metadata filtering) optimized for LLM consumption.
- Stay up to date with modern technologies and best practices for building Gen AI-based applications.
Required skills & knowledge:
- Proficiency in TypeScript and Node.js.
- Good understanding of software design principles, design patterns, and modern development best practices.
- Experience with NoSQL databases; familiarity with vector databases (OpenSearch a plus).
- Familiarity with AI agent workflows (tool-use, memory, and context management), or a strong interest in building them.
- Basic understanding of agentic behaviors and patterns, such as planning, retrieval, and self-correction.
- Exposure to LangChain and/or LangGraph libraries (or a strong willingness to ramp up quickly).
- Understanding of RAG workflows; hands-on experience is a plus.
- Familiarity with evaluation and testing approaches for AI systems.
Nice to have:
