  • Build and scale full-stack apps (React, Next.js, Node.js)
  • Integrate AI APIs (Gemini, OpenAI, Anthropic) and agent workflows
  • Work with vector DBs (Pinecone, Weaviate, Qdrant, etc.) for retrieval systems
  • Ship fast, from prototype to production
  • Collaborate with design and product teams to bring ideas to life

Requirements

Must-Have Skills
  • Front-End: React, Next.js, Tailwind, TypeScript
  • Back-End: Node.js, Express, REST/GraphQL APIs
  • Databases: MongoDB, Redis, and at least one Vector DB (Pinecone, Qdrant, Weaviate, Milvus, etc.)
Bonus Points
  • Experience with Puppeteer, Playwright, or large-scale web scraping
  • Experience building RAG systems or multimodal AI tools
  • Familiarity with LangChain, LlamaIndex, or similar agent frameworks
  • Strong sense of product, performance, and UI/UX details
  • AWS, Vercel, or Docker experience

Benefits

  • Cutting-edge work: Learn from the leaders in the high-growth Conversion Rate Optimization sector.
  • Work location: Permanently remote
  • Full-time position with semi-flexible working hours: Must overlap for at least 4 hours each day with ET (usually 8 AM to 12 PM EST), the other 4 hours are up to you!
  • Technological reimbursement: Need a new computer? New software? We will help!
  • Education: You’ll have the opportunity to level up your skills with company-sponsored courses and training.
  • 20 days of paid vacation plus holidays.
