You will be expected to translate ambiguous product goals into reliable, scalable solutions, contribute directly to core platform architecture, and collaborate closely with product, design, and leadership to deliver real-world AI capabilities used in production by customers. Job requirements Hands-on implementation of LLM-powered systems (applications, agents, workflows). Experience with RAG, embeddings, vector search, or evaluation methodologies. Familiarity with tool/agent orchestration frameworks (LangChain, LangGraph, LlamaIndex, custom frameworks, etc.). Understanding of model behaviour, prompting strategies, and practical guardrail patterns. Strong programming ability in TypeScript, React, Node.js Experience building user-facing and backend systems end-to-end. Ability to contribute across the entire stack without needing months of ramp-up. 5–10+ years professional engineering experience (typically senior-level).

Build full-stack product features using TypeScript, React, Node.js, and modern tooling. Contribute to the development of our observability and AI-tracing systems Build internal frameworks and reusable components that accelerate GenAI feature delivery. Take end-to-end ownership of features—from requirements shaping through implementation, testing, release, and iteration. Operate autonomously in ambiguity, making pragmatic engineering decisions aligned with product goals. Diagnose and improve performance, reliability, and quality of AI-driven systems. Partner closely with Product, Design, and other Engineers to shape solutions. Participate actively in code reviews, architectural discussions, and internal technical debates.
