LLM Engineer - Web Platform AI Agent

We’re looking for a passionate and experienced LLM Engineer to join our Innovation Lab team in building intelligent agents for the web. This role focuses on designing, developing, and integrating Large Language Model (LLM) powered agents directly into our web platform, enabling dynamic, context-aware, and autonomous experiences for end users and developers alike.

You’ll be at the forefront of AI / UX platform innovation, creating agents that can assist, automate, and enhance workflows across a range of web applications—from developer tools and dashboards to customer-facing UIs.

What You’ll Do

• Design and implement AI agents powered by LLMs for our web platform, supporting rich interaction patterns, autonomy, and contextual intelligence.
• Build agentic workflows that can plan, reason, and take actions within the browser or across platform APIs.
• Work with product and UX teams to define intelligent behaviors and assistive features inside web apps.
• Fine-tune, prompt-engineer, or integrate LLMs (e.g., OpenAI, Anthropic, open-source models) for platform-specific use cases.
• Collaborate with frontend engineers to embed agents into modern web apps using technologies like WebComponents, Event Sourcing or custom design systems.
• Develop and maintain infrastructure for prompt orchestration, memory, context management, and tools integration.
• Explore and implement retrieval-augmented generation (RAG), tool use, and multimodal interfaces.
• Evaluate performance, safety, and user experience of deployed agents, and iterate based on feedback.

Requirements

• Strong experience with LLMs (e.g., OpenAI, Claude, Mistral, Llama) and their ecosystem (prompting, tooling, APIs, embeddings).
• Solid engineering background in Python or TypeScript/JavaScript.
• Experience building agent frameworks or working with open-source ones (LangChain, Semantic Kernel, AutoGen, etc.)
• Familiarity with web platform architecture, including CQRS and Event Sourcing methodologies, service APIs, authentication, and browser automation.
• Passion for UX and creating intuitive, human-centered AI interactions.
• Strong problem-solving skills and ability to work in cross-functional teams.
• Bonus: Experience with multi-agent systems, memory architectures, or AI planning/reasoning techniques.
