The problem: 85% of B2B website visitors leave without interaction. Meanwhile, they use ChatGPT and Perplexity to compare solutions before even contacting you.
Our mission: Transform B2B websites into intelligent conversational assistants that engage 100% of traffic, capture quality zero-party data, and increase demo conversions.
Our approach: Unlike traditional chatbots (~5% engagement), Rose achieves 20%+ engagement through an integrated assistant experience, not an intrusive popup.
Our clients: Pennylane, Mayday, AB Tasty are already using Rose in production.
You'll join Rose as the first Founding Engineer to build the platform alongside, Benoit, CTO/Cofounder.
You'll work on cutting-edge technical challenges in an environment where every line of code has a direct impact on the product and users.
Your missionsArchitecture & Development
Co-build the technical architecture with the CTO (backend, frontend, infrastructure)
Develop core features: conversational AI engine, interactive experiences, third-party integrations, back-office
Make technical choices that structure the platform for the next 5 years.
AI & Performance
Participate to the implementation of RAG (Retrieval-Augmented Generation) systems in production with Vector database and knowledge graph
Optimize real-time performance
Develop guardrails and testing mechanisms to ensure AI response quality.
Integrations & Product
Build bidirectional integrations with CRMs (Salesforce, HubSpot)
Orchestrate calendar systems (Calendly, Chili Piper) and analytics (Posthog)
Participate in product decisions and user exchanges.
Backend: Python, Fast API, PostgreSQL, MongoDB Vector Database, Neo4j
Frontend: React, TypeScript AI/ML: LLMs, Vector embeddings, prompt engineering, Langgraph
Infrastructure: GCP, GitHub Actions, monitoring and observability.
- We favor pragmatism over theoretical perfection, iteration velocity over over-engineered architectures, and user impact over technical elegance. You'll work in an environment where we ship quickly, test with real users every week, and learn constantly.
