Experience:

• 2–4 years of professional experience with a backend focus and solid full-stack instincts

Role Focus:

• Design, build & maintain scalable backend services and APIs that power GenAI features across the VWO platform
• Develop GenAI applications end-to-end — agents, copilots, and automations — from early prototype through production
• Orchestrate agentic workflows using frameworks like CrewAI, Autogen, or LangGraph, and integrate them seamlessly into product surfaces
• Implement retrieval and memory patterns (RAG, session and long-term memory, summarisation) backed by vector and graph stores
• Own quality in production: observability, cost and latency optimisation, evaluation frameworks, and safety guardrails
• Collaborate cross-functionally with design and frontend (React) and with product to shape the GenAI roadmap
• Partner with internal business owners across sales, marketing, and operations — understand their workflows and translate requirements into GenAI solutions that drive measurable impact
• Improve sales efficiency and business processes by identifying automation opportunities and delivering agentic workflows tailored to GTM stakeholder needs

Nice to have:

• Experience with LangSmith, Langfuse, Weights & Biases, prompt management systems, and evaluation frameworks
• Experience with vector and graph databases such as pgvector, Pinecone, Weaviate, Neo4j, or similar
• Deep understanding of retrieval optimization, hybrid search, and context-window management
• Experience hosting and serving open-source models alongside commercial APIs such as OpenAI and Anthropic
• Familiarity with embeddings pipelines, AI safety tooling, and guardrail frameworks
• Experience building products from 0→1
• Strong product intuition and customer-centric thinking

More skills:

Node.js/TypeScript, REST/GraphQL, LangChain/LangGraph, graph stores, React

Other:

• Operate with startup agility inside a successful global SaaS company
• Own problems end-to-end and see your work reach customers quickly
• Work alongside experienced engineers and product leaders while gaining exposure to cutting-edge GenAI technologies and real-world AI deployment challenges
• Join a highly collaborative, low-ego engineering culture that values craftsmanship, curiosity, and impact
