Senior Full-Stack Engineer (React + AI)
Location: Remote (North America or Latin America) Experience Level: Senior/Staff (8+ years) Employment Type: Full-time
About the Role
This is a rare chance to build cutting-edge, AI-native business software from the ground up and to help define what it looks like. We're looking for a Senior Full-Stack Engineer who can move fast, ship real product, and work shoulder-to-shoulder with senior leadership to turn ambitious ideas into working systems. You'll be at the center of building production applications, with direct influence over the technical direction we take. This is primarily a product engineering role. Much of your time will be spent building polished, production-grade React applications with a meaningful and growing component focused on integrating real AI capabilities: modern AI APIs and SDKs, retrieval-augmented generation (RAG), and protocols like MCP. It's fast-paced, high-ownership work for someone who wants their fingerprints on both the product and the architecture.

Direction: Make pragmatic architecture decisions and help shape the technical roadmap alongside senior leadership
- Technical Leadership: Collaborate with DevOps on CI/CD pipelines and build processes;
mentor team members on best practices AI Integration
- AI Feature Development: Integrate AI provider APIs and SDKs (e.g., OpenAI, Anthropic,
Google) into production applications to build reliable, user-facing AI features
- RAG & Retrieval: Build retrieval-augmented generation features that let AI work over
data and content
- AI Tooling &
Integrations: Connect AI systems to internal tools, APIs, and data sources using MCP and similar frameworks
- Quality & Performance: Help keep AI features accurate, fast, and cost-effective in
production
